可以說(shuō)，珀金斯1.7柴油機(jī)已然成為眾多設(shè)備穩(wěn)定運(yùn)行的核心動(dòng)力源泉，其重要性不言而喻。一旦這一關(guān)鍵動(dòng)力組件出現(xiàn)故障，相關(guān)設(shè)備便可能陷入停滯，給生產(chǎn)生活帶來(lái)諸多不便與損失。正因如此，深入了解珀金斯1.7柴油機(jī)配件以及掌握其維修技術(shù)支持，對(duì)于保障設(shè)備的正常運(yùn)行、提高生產(chǎn)效率、降低運(yùn)營(yíng)成本而言，顯得尤為重要。

探秘珀金斯1.7柴油機(jī)配件
（一）常用配件大盤(pán)點(diǎn)
濾清器是保障發(fā)動(dòng)機(jī)“呼吸”順暢與“飲食”清潔的關(guān)鍵防線(xiàn)。空氣濾清器能有效濾除空氣中的灰塵、雜質(zhì)，確保進(jìn)入發(fā)動(dòng)機(jī)的空氣純凈，減少氣缸、活塞等部件的磨損。一旦空氣濾清器堵塞，發(fā)動(dòng)機(jī)進(jìn)氣量不足，會(huì)導(dǎo)致燃燒不充分，功率下降，油耗增加，就像人戴著堵塞的口罩呼吸，會(huì)感到憋悶難受。燃油濾清器則專(zhuān)注于過(guò)濾燃油中的雜質(zhì)和水分，為噴油系統(tǒng)提供清潔的燃油，防止噴油嘴堵塞、磨損，保證發(fā)動(dòng)機(jī)的燃油供給穩(wěn)定，燃燒高效。機(jī)油濾清器負(fù)責(zé)過(guò)濾機(jī)油中的金屬碎屑、雜質(zhì)等，維持機(jī)油的清潔度，讓機(jī)油能充分發(fā)揮潤(rùn)滑、冷卻作用，保護(hù)發(fā)動(dòng)機(jī)各運(yùn)動(dòng)部件。
皮帶在發(fā)動(dòng)機(jī)中扮演著動(dòng)力傳遞的重要角色。常見(jiàn)的有風(fēng)扇皮帶、發(fā)電機(jī)皮帶等。風(fēng)扇皮帶帶動(dòng)風(fēng)扇運(yùn)轉(zhuǎn)，為發(fā)動(dòng)機(jī)散熱，確保發(fā)動(dòng)機(jī)在適宜的溫度下工作。若風(fēng)扇皮帶松弛或斷裂，發(fā)動(dòng)機(jī)散熱不良，會(huì)出現(xiàn)過(guò)熱現(xiàn)象，嚴(yán)重時(shí)可能導(dǎo)致發(fā)動(dòng)機(jī)損壞。發(fā)電機(jī)皮帶則將發(fā)動(dòng)機(jī)的動(dòng)力傳遞給發(fā)電機(jī)，使發(fā)電機(jī)發(fā)電，為車(chē)輛的電氣系統(tǒng)提供電力。如果發(fā)電機(jī)皮帶故障，車(chē)輛的電池?zé)o法充電，電氣設(shè)備將無(wú)法正常工作。
修理包是包含了多種密封件和墊片的集合，如氣缸墊、油底殼墊、油封等。氣缸墊用于密封氣缸體和氣缸蓋，防止漏氣、漏水和漏油，保證發(fā)動(dòng)機(jī)的正常壓縮比和燃燒效率。油底殼墊則防止機(jī)油泄漏，維持發(fā)動(dòng)機(jī)潤(rùn)滑系統(tǒng)的正常工作。油封用于密封旋轉(zhuǎn)部件，防止機(jī)油泄漏，保證發(fā)動(dòng)機(jī)的密封性。這些密封件和墊片雖小，卻對(duì)發(fā)動(dòng)機(jī)的性能和可靠性有著重要影響。
（二）關(guān)鍵大修配件解析
活塞堪稱(chēng)發(fā)動(dòng)機(jī)的“心臟起搏器”，在燃燒室內(nèi)，柴油燃燒產(chǎn)生的高溫高壓氣體推動(dòng)活塞向下運(yùn)動(dòng)，帶動(dòng)曲軸轉(zhuǎn)動(dòng)，實(shí)現(xiàn)熱能到機(jī)械能的轉(zhuǎn)化，驅(qū)動(dòng)設(shè)備運(yùn)行。同時(shí)，活塞與氣缸壁之間通過(guò)活塞環(huán)保持良好的密封性，防止氣缸內(nèi)氣體泄漏，保證發(fā)動(dòng)機(jī)的正常工作壓力?；钊牟馁|(zhì)和結(jié)構(gòu)設(shè)計(jì)需具備足夠的強(qiáng)度和剛度，以承受巨大的壓力和沖擊力。
缸套作為活塞運(yùn)動(dòng)的“軌道”，直接與高溫高壓的燃?xì)饨佑|，承受著高溫、高壓和摩擦的考驗(yàn)。它不僅為活塞提供導(dǎo)向，還能幫助活塞散熱，保證活塞的正常工作。優(yōu)質(zhì)的缸套材質(zhì)和精密的加工工藝，能確保缸套的耐磨性和尺寸精度，延長(zhǎng)發(fā)動(dòng)機(jī)的使用壽命。
曲軸是發(fā)動(dòng)機(jī)的“動(dòng)力輸出軸”，它將活塞的往復(fù)直線(xiàn)運(yùn)動(dòng)轉(zhuǎn)化為旋轉(zhuǎn)運(yùn)動(dòng)，輸出動(dòng)力。曲軸在工作過(guò)程中承受著巨大的扭矩和彎曲力，因此需要具備極高的強(qiáng)度和剛度。曲軸的加工精度和動(dòng)平衡性能對(duì)發(fā)動(dòng)機(jī)的平穩(wěn)運(yùn)行至關(guān)重要，哪怕是微小的偏差，都可能導(dǎo)致發(fā)動(dòng)機(jī)振動(dòng)加劇、噪音增大，甚至引發(fā)嚴(yán)重故障。

（三）原廠(chǎng)與副廠(chǎng)配件的抉擇
原廠(chǎng)配件由珀金斯公司直接生產(chǎn)或授權(quán)生產(chǎn)，嚴(yán)格遵循發(fā)動(dòng)機(jī)的設(shè)計(jì)規(guī)格和制造標(biāo)準(zhǔn)。其質(zhì)量經(jīng)過(guò)了層層嚴(yán)格的把控和檢測(cè)，在性能上與發(fā)動(dòng)機(jī)完美匹配，能確保發(fā)動(dòng)機(jī)發(fā)揮出最佳性能，提供更高的安全保障和更長(zhǎng)的使用壽命。并且，原廠(chǎng)配件通常能獲得廠(chǎng)家的技術(shù)支持和完善的售后服務(wù)保障，如質(zhì)量保修、技術(shù)指導(dǎo)等。然而，原廠(chǎng)配件的價(jià)格相對(duì)較高，供應(yīng)渠道有時(shí)較為有限，可能需要等待較長(zhǎng)時(shí)間才能到貨。
副廠(chǎng)配件由第三方廠(chǎng)家生產(chǎn)，沒(méi)有得到珀金斯公司的授權(quán)。部分副廠(chǎng)配件在質(zhì)量和性能上也能達(dá)到一定標(biāo)準(zhǔn)，且價(jià)格相對(duì)較低，能為用戶(hù)節(jié)省成本。但副廠(chǎng)配件市場(chǎng)魚(yú)龍混雜，部分產(chǎn)品的生產(chǎn)標(biāo)準(zhǔn)和材料選擇可能不符合發(fā)動(dòng)機(jī)的規(guī)格要求，存在質(zhì)量參差不齊的問(wèn)題。這些劣質(zhì)副廠(chǎng)配件可能無(wú)法完全適應(yīng)發(fā)動(dòng)機(jī)的工作環(huán)境，導(dǎo)致性能下降、故障頻發(fā)，甚至對(duì)發(fā)動(dòng)機(jī)造成嚴(yán)重?fù)p壞，而且在售后服務(wù)方面也往往難以得到有效保障。
在選擇配件時(shí)，如果追求發(fā)動(dòng)機(jī)的最佳性能、可靠性和長(zhǎng)期穩(wěn)定運(yùn)行，對(duì)設(shè)備的使用安全有較高要求，那么原廠(chǎng)配件無(wú)疑是最佳選擇。若預(yù)算有限，且能確保選擇的副廠(chǎng)配件質(zhì)量可靠、來(lái)源正規(guī)，也可考慮副廠(chǎng)配件，但需謹(jǐn)慎篩選，密切關(guān)注使用效果。

珀金斯1.7柴油機(jī)維修技術(shù)深度剖析
（一）常見(jiàn)故障診斷方法
當(dāng)珀金斯1.7柴油機(jī)出現(xiàn)啟動(dòng)困難的情況時(shí)，我們可以從多個(gè)方面進(jìn)行初步診斷。先聽(tīng)聲音，啟動(dòng)時(shí)若起動(dòng)機(jī)運(yùn)轉(zhuǎn)正常，但發(fā)動(dòng)機(jī)無(wú)著火跡象，可能是燃油系統(tǒng)故障；若有“噠噠”聲，可能是氣門(mén)間隙過(guò)大或啟動(dòng)機(jī)齒輪與飛輪齒圈嚙合不良。再看排氣，若排氣口大量冒白煙，可能是柴油中有水或氣缸墊損壞導(dǎo)致冷卻水進(jìn)入氣缸；冒黑煙則可能是燃燒不充分，空氣濾清器堵塞或噴油過(guò)多。還需檢查儀表，查看機(jī)油壓力、水溫等儀表讀數(shù)，若機(jī)油壓力過(guò)低，可能影響發(fā)動(dòng)機(jī)啟動(dòng)。
若是發(fā)動(dòng)機(jī)功率不足，聽(tīng)聲音時(shí)，若發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)聲音沉悶，可能是負(fù)荷過(guò)大或內(nèi)部有故障。看排氣，冒黑煙且動(dòng)力不足，可能是空氣濾清器堵塞、噴油嘴霧化不良或供油提前角不對(duì)。檢查儀表，關(guān)注機(jī)油溫度、冷卻液溫度，若過(guò)高，ECU可能進(jìn)入過(guò)熱保護(hù)模式，限制發(fā)動(dòng)機(jī)功率。
對(duì)于發(fā)動(dòng)機(jī)異常響聲，不同的聲音往往暗示著不同的故障。若是清脆的“當(dāng)當(dāng)”聲，可能是活塞敲缸，原因可能是活塞與氣缸壁間隙過(guò)大；若是連續(xù)的“嗡嗡”聲，可能是軸承磨損，軸承間隙過(guò)大；若是尖銳的“吱吱”聲，可能是皮帶打滑，皮帶過(guò)松或磨損嚴(yán)重。

（二）針對(duì)性維修策略
針對(duì)啟動(dòng)困難，若確定是燃油系統(tǒng)問(wèn)題，比如燃油濾清器堵塞，需及時(shí)更換濾芯；噴油器故障，如噴油嘴積碳、噴油壓力不足，可進(jìn)行清洗、研磨或更換噴油器。若是啟動(dòng)電機(jī)故障，出現(xiàn)碳刷磨損、轉(zhuǎn)子卡滯等情況，要維修或更換啟動(dòng)電機(jī)。
當(dāng)發(fā)動(dòng)機(jī)功率不足時(shí)，如果是空氣濾清器不清潔，增加了阻力，導(dǎo)致空氣流量減少，充氣效率下降，應(yīng)定期清洗柴油空氣濾清器芯子，清除積塵，必要時(shí)更換濾芯。若是供油提前角過(guò)大或過(guò)小，造成油泵噴油時(shí)間過(guò)早或過(guò)晚，使燃燒過(guò)程不是處于最佳狀態(tài)，應(yīng)檢查噴油傳動(dòng)軸接合器螺釘是否松動(dòng)，如果松動(dòng)，則應(yīng)重新按照要求調(diào)整供油提前角，并擰緊螺釘。要是活塞與缸套拉傷，造成摩擦損失增大，發(fā)動(dòng)機(jī)自身的機(jī)械損失增大，壓縮比減小，著火困難或燃燒不充分，此時(shí)，應(yīng)更換缸套、活塞和活塞環(huán)。
面對(duì)發(fā)動(dòng)機(jī)異常響聲，若因氣門(mén)間隙過(guò)大產(chǎn)生異響，可依據(jù)維修手冊(cè)，使用塞尺等工具，精準(zhǔn)調(diào)整氣門(mén)間隙。要是噴油提前角過(guò)大導(dǎo)致的異常響聲，需重新校準(zhǔn)噴油提前角，確保噴油時(shí)機(jī)精準(zhǔn)。如果是柴油標(biāo)號(hào)不符合標(biāo)準(zhǔn)引發(fā)的問(wèn)題，應(yīng)更換符合要求的柴油，保證燃油質(zhì)量。
（三）維修中的注意事項(xiàng)
維修過(guò)程中，安全操作至關(guān)重要。維修前，必須關(guān)閉柴油機(jī)，等待其完全冷卻，防止?fàn)C傷。維修人員要佩戴好防護(hù)手套、護(hù)目鏡等裝備，避免在操作過(guò)程中受傷。同時(shí)，要在通風(fēng)良好的環(huán)境中進(jìn)行維修，防止吸入有害氣體。
在工具使用方面，務(wù)必選用合適的工具，嚴(yán)禁使用損壞或不合適的工具。拆卸和安裝部件時(shí)，要嚴(yán)格按照規(guī)定的扭矩使用扭力扳手，避免因扭矩過(guò)大或過(guò)小導(dǎo)致部件損壞或安裝不牢固。比如，在拆卸和安裝氣缸蓋螺栓時(shí)，要按照規(guī)定的扭矩和順序進(jìn)行操作，確保氣缸蓋密封良好。
配件安裝規(guī)范同樣不可忽視。安裝新配件前，要仔細(xì)檢查其型號(hào)、規(guī)格是否與原配件一致，確保配件質(zhì)量合格。安裝時(shí)，要注意清潔部件表面，涂抹適量的潤(rùn)滑油，保證安裝位置準(zhǔn)確，避免出現(xiàn)錯(cuò)位、漏裝等情況。像安裝活塞環(huán)時(shí)，要注意活塞環(huán)的開(kāi)口方向和間隙，確?；钊h(huán)的密封性能良好。

（一）定期保養(yǎng)計(jì)劃
為了確保珀金斯1.7柴油機(jī)始終保持良好的運(yùn)行狀態(tài)，制定一份科學(xué)合理的定期保養(yǎng)計(jì)劃至關(guān)重要。在新機(jī)初次使用時(shí)，當(dāng)累計(jì)工作達(dá)到60小時(shí)，就需要進(jìn)行一次全面的保養(yǎng)。此時(shí)，要及時(shí)更換柴油濾芯、機(jī)油濾芯和柴油機(jī)油，這些關(guān)鍵部件的及時(shí)更換，能有效清除燃油、機(jī)油中的雜質(zhì)，防止它們對(duì)發(fā)動(dòng)機(jī)內(nèi)部精密部件造成磨損，為發(fā)動(dòng)機(jī)的穩(wěn)定運(yùn)行奠定基礎(chǔ)。
隨著使用時(shí)間的增加，在后續(xù)的使用過(guò)程中，每工作250小時(shí)，便要再次更換柴油濾芯、機(jī)油濾芯和柴油機(jī)油，保持發(fā)動(dòng)機(jī)內(nèi)部的清潔環(huán)境。同時(shí)，根據(jù)機(jī)組的使用環(huán)境，當(dāng)工作時(shí)長(zhǎng)達(dá)到300-600小時(shí)時(shí)，需對(duì)空氣濾芯進(jìn)行更換。在灰塵較多的環(huán)境中使用，空氣濾芯的更換頻率應(yīng)適當(dāng)提高，確保進(jìn)入發(fā)動(dòng)機(jī)的空氣始終保持清潔，避免因空氣雜質(zhì)過(guò)多導(dǎo)致發(fā)動(dòng)機(jī)氣缸、活塞等部件過(guò)度磨損。
如果柴油機(jī)不經(jīng)常使用，也不能忽視保養(yǎng)工作。每隔半年，就需要更換一次柴油機(jī)油，防止機(jī)油因長(zhǎng)時(shí)間靜置而變質(zhì)，失去應(yīng)有的潤(rùn)滑和保護(hù)性能。
（二）正確使用與維護(hù)方法
在啟動(dòng)珀金斯1.7柴油機(jī)之前，要進(jìn)行全面細(xì)致的檢查。先查看油底殼中的機(jī)油液位，應(yīng)保持在油標(biāo)尺上、下標(biāo)記之間，確保發(fā)動(dòng)機(jī)各運(yùn)動(dòng)部件有足夠的潤(rùn)滑。檢查冷卻系統(tǒng)，加滿(mǎn)冷卻水，保證發(fā)動(dòng)機(jī)在運(yùn)行過(guò)程中能夠有效散熱，防止過(guò)熱損壞。還要檢查燃油箱中的存油量，打開(kāi)燃油開(kāi)關(guān)，使柴油流向輸油泵，并排除燃油系統(tǒng)內(nèi)的空氣，避免因空氣進(jìn)入燃油系統(tǒng)導(dǎo)致啟動(dòng)困難。同時(shí)，檢查蓄電池充電是否充足，確保啟動(dòng)電機(jī)有足夠的電力驅(qū)動(dòng)發(fā)動(dòng)機(jī)啟動(dòng)。
啟動(dòng)時(shí)，若環(huán)境溫度較低，帶預(yù)熱塞的機(jī)器可采用預(yù)熱起動(dòng)方式。將鑰匙開(kāi)關(guān)轉(zhuǎn)至“預(yù)熱”位置，停留40-50秒，讓預(yù)熱塞對(duì)燃燒室進(jìn)行預(yù)熱，提高燃油的霧化效果和燃燒效率。每次啟動(dòng)時(shí)間不應(yīng)超過(guò)5秒，以保護(hù)啟動(dòng)電機(jī)和蓄電池。如需連續(xù)啟動(dòng)，應(yīng)停歇2分鐘后再行起動(dòng)。如果連續(xù)三次不能起動(dòng)，就需要排查故障原因，切勿盲目多次啟動(dòng)，以免損壞設(shè)備。
柴油機(jī)運(yùn)行過(guò)程中，要密切關(guān)注各項(xiàng)儀表參數(shù)，如機(jī)油壓力、水溫、轉(zhuǎn)速等。機(jī)油壓力過(guò)低，可能意味著機(jī)油不足、機(jī)油泵故障或油路堵塞，會(huì)導(dǎo)致發(fā)動(dòng)機(jī)潤(rùn)滑不良，加劇部件磨損；水溫過(guò)高，表明發(fā)動(dòng)機(jī)散熱出現(xiàn)問(wèn)題，可能是冷卻系統(tǒng)故障、冷卻液不足或風(fēng)扇皮帶松弛等原因引起，長(zhǎng)時(shí)間高溫運(yùn)行會(huì)使發(fā)動(dòng)機(jī)零部件變形、損壞；轉(zhuǎn)速異常則可能暗示著發(fā)動(dòng)機(jī)負(fù)荷不均、燃油供應(yīng)不暢或調(diào)速器故障等。一旦發(fā)現(xiàn)儀表參數(shù)異常，應(yīng)立即停機(jī)檢查，排除故障后再繼續(xù)運(yùn)行。
停機(jī)時(shí)，也不能隨意操作。先逐漸降低柴油機(jī)的負(fù)荷和轉(zhuǎn)速，讓發(fā)動(dòng)機(jī)在怠速狀態(tài)下運(yùn)行3-5分鐘，使各部件得到充分的冷卻和潤(rùn)滑，避免因突然停機(jī)導(dǎo)致零部件過(guò)熱損壞或機(jī)油未能充分回流。然后關(guān)閉燃油開(kāi)關(guān)，切斷燃油供應(yīng)，再關(guān)閉電源開(kāi)關(guān)，完成停機(jī)操作。
在日常維護(hù)中，對(duì)油液的檢查不容忽視。定期檢查機(jī)油的質(zhì)量和液位，觀(guān)察機(jī)油的顏色和粘度，若機(jī)油顏色變黑、粘度下降，說(shuō)明機(jī)油已變質(zhì)，需要及時(shí)更換。同時(shí)，檢查冷卻液的液位和濃度，確保冷卻液具有良好的防凍、防沸和防腐性能。還要檢查燃油的質(zhì)量，避免使用劣質(zhì)燃油，防止燃油中的雜質(zhì)和水分對(duì)燃油系統(tǒng)造成損害。
濾清器的檢查和維護(hù)同樣關(guān)鍵。定期清理空氣濾清器的濾芯，可使用壓縮空氣從濾芯內(nèi)部向外吹，清除灰塵和雜質(zhì)。若發(fā)現(xiàn)濾芯破損或堵塞嚴(yán)重，應(yīng)及時(shí)更換。對(duì)于燃油濾清器和機(jī)油濾清器，也要按照規(guī)定的時(shí)間和里程進(jìn)行更換，保證其過(guò)濾效果，為發(fā)動(dòng)機(jī)提供清潔的燃油和機(jī)油。

Exploring Perkins 1.7 Diesel Engine Parts
（1） List of commonly used accessories
The filter is a key line of defense to ensure smooth engine breathing and clean diet. Air filters can effectively filter out dust and impurities in the air, ensuring the purity of the air entering the engine and reducing wear on components such as cylinders and pistons. Once the air filter is clogged and the engine intake is insufficient, it will lead to insufficient combustion, decreased power, and increased fuel consumption, just like when a person wears a clogged mask to breathe, they will feel suffocated and uncomfortable. The fuel filter focuses on filtering impurities and moisture in the fuel, providing clean fuel for the fuel injection system, preventing nozzle blockage and wear, ensuring stable fuel supply to the engine, and efficient combustion. The oil filter is responsible for filtering metal debris, impurities, etc. in the engine oil, maintaining the cleanliness of the oil, allowing the oil to fully exert its lubrication and cooling effects, and protecting various moving parts of the engine.
Belts play an important role in power transmission in engines. Common ones include fan belts, generator belts, etc. The fan belt drives the fan to operate, dissipating heat from the engine and ensuring that the engine operates at a suitable temperature. If the fan belt is loose or broken, poor engine heat dissipation may occur, leading to overheating and, in severe cases, engine damage. The generator belt transfers the power of the engine to the generator, causing it to generate electricity and provide power for the vehicle's electrical system. If the generator belt malfunctions, the vehicle's battery cannot be charged and the electrical equipment will not function properly.
A repair kit is a collection of various seals and gaskets, such as cylinder gaskets, oil pan gaskets, oil seals, etc. Cylinder gaskets are used to seal the cylinder block and cylinder head, preventing air, water, and oil leaks, ensuring the normal compression ratio and combustion efficiency of the engine. The oil pan gasket prevents oil leakage and maintains the normal operation of the engine lubrication system. Oil seals are used to seal rotating components, prevent oil leakage, and ensure the sealing of the engine. Although these seals and gaskets are small, they have a significant impact on the performance and reliability of the engine.
（2） Analysis of key overhaul components
The piston can be called the "pacemaker" of the engine. In the combustion chamber, the high-temperature and high-pressure gas generated by diesel combustion pushes the piston downwards, drives the crankshaft to rotate, and converts thermal energy into mechanical energy, driving the equipment to operate. At the same time, the piston and cylinder wall maintain good sealing through the piston ring, preventing gas leakage inside the cylinder and ensuring the normal working pressure of the engine. The material and structural design of the piston need to have sufficient strength and stiffness to withstand enormous pressure and impact forces.
The cylinder liner, as the "track" of piston movement, is in direct contact with high-temperature and high-pressure gas, and is subjected to the test of high temperature, high pressure, and friction. It not only provides guidance for the piston, but also helps to dissipate heat and ensure the normal operation of the piston. High quality cylinder liner material and precision machining technology can ensure the wear resistance and dimensional accuracy of the cylinder liner, extending the service life of the engine.
The crankshaft is the "power output shaft" of the engine, which converts the reciprocating linear motion of the piston into rotational motion and outputs power. The crankshaft bears enormous torque and bending force during operation, thus requiring extremely high strength and stiffness. The machining accuracy and dynamic balance performance of the crankshaft are crucial for the smooth operation of the engine. Even small deviations can lead to increased engine vibration, noise, and even serious malfunctions.
（3） The choice between original and subsidiary accessories
The original accessories are directly produced or authorized for production by Perkins, strictly following the design specifications and manufacturing standards of the engine. Its quality has undergone strict control and testing at every level, perfectly matching the performance of the engine, ensuring that the engine can perform at its best, providing higher safety guarantees and longer service life. Moreover, original accessories usually receive technical support and comprehensive after-sales service guarantees from the manufacturer, such as quality warranty, technical guidance, etc. However, the price of original accessories is relatively high, and the supply channels are sometimes limited, which may require a long wait for delivery.
The auxiliary accessories are produced by third-party manufacturers without authorization from Perkins Inc. Some aftermarket accessories can also meet certain standards in quality and performance, and their prices are relatively low, which can save costs for users. However, the aftermarket parts market is mixed with good and bad products, and the production standards and material selection of some products may not meet the specifications of the engine, resulting in uneven quality. These inferior aftermarket parts may not fully adapt to the working environment of the engine, resulting in decreased performance, frequent malfunctions, and even serious damage to the engine. Moreover, effective after-sales service is often difficult to guarantee.
When choosing accessories, if you pursue the best performance, reliability, and long-term stable operation of the engine, and have high requirements for the safety of equipment use, then original accessories are undoubtedly the best choice. If the budget is limited and it can ensure the reliable quality and legitimate source of the selected secondary factory accessories, secondary factory accessories can also be considered, but careful screening and close attention to their effectiveness should be paid.
In depth Analysis of Perkins 1.7 Diesel Engine Maintenance Technology
（1） Common fault diagnosis methods
When the Perkins 1.7 diesel engine experiences difficulty starting, we can make a preliminary diagnosis from multiple aspects. Listen to the sound first. If the starter motor runs normally during startup but there are no signs of ignition in the engine, it may be a fuel system malfunction; If there is a "click" sound, it may be due to excessive valve clearance or poor meshing between the starter gear and the flywheel ring gear. Looking at the exhaust again, if a large amount of white smoke is emitted from the exhaust port, it may be due to water in the diesel or damage to the cylinder gasket causing cooling water to enter the cylinder; Black smoke may indicate insufficient combustion, clogged air filter, or excessive fuel injection. It is also necessary to check the instruments, such as oil pressure and water temperature readings. If the oil pressure is too low, it may affect the engine starting.
If the engine power is insufficient and the sound is dull when listening, it may be due to excessive load or internal malfunction. Looking at the exhaust, black smoke and insufficient power may be due to clogged air filters, poor atomization of fuel injectors, or incorrect fuel supply timing. Check the instrument panel and pay attention to the oil temperature and coolant temperature. If they are too high, the ECU may enter overheat protection mode and limit engine power.
For abnormal engine noise, different sounds often indicate different faults. If there is a crisp "dang dang" sound, it may be a piston knocking on the cylinder, and the reason may be that the clearance between the piston and the cylinder wall is too large; If there is a continuous buzzing sound, it may be due to bearing wear and excessive bearing clearance; If there is a sharp "squeaking" sound, it may be due to the belt slipping, the belt being too loose or severely worn.
（2） Targeted maintenance strategy
For start-up difficulties, if it is determined to be a fuel system issue, such as a clogged fuel filter, the filter element needs to be replaced in a timely manner; Fuel injector malfunction, such as carbon buildup on the fuel injector nozzle or insufficient fuel injection pressure, can be cleaned, ground, or replaced. If there is a malfunction in the starter motor, such as carbon brush wear, rotor jamming, etc., the starter motor should be repaired or replaced.
When the engine power is insufficient, if the air filter is not clean and increases resistance, resulting in a decrease in air flow and a decrease in inflation efficiency, the diesel air filter element should be cleaned regularly to remove dust and replace the element if necessary. If the fuel supply advance angle is too large or too small, causing the fuel pump to inject too early or too late, resulting in the combustion process not being in the optimal state, the screw of the fuel injection transmission shaft adapter should be checked for looseness. If it is loose, the fuel supply advance angle should be adjusted again according to the requirements and the screw should be tightened. If the piston and cylinder liner are pulled, causing increased friction loss, increased mechanical loss of the engine itself, decreased compression ratio, difficulty in ignition or insufficient combustion, then the cylinder liner, piston, and piston ring should be replaced.
In the face of abnormal engine noise, if the abnormal noise is caused by excessive valve clearance, the valve clearance can be accurately adjusted using tools such as a feeler gauge according to the maintenance manual. If the abnormal noise is caused by excessive fuel injection advance angle, the fuel injection advance angle needs to be recalibrated to ensure accurate fuel injection timing. If the problem is caused by the diesel grade not meeting the standards, it should be replaced with diesel that meets the requirements to ensure fuel quality.
（3） Precautions during maintenance
Safe operation is crucial during the maintenance process. Before maintenance, the diesel engine must be turned off and allowed to cool completely to prevent burns. Maintenance personnel should wear protective gloves, goggles, and other equipment to avoid injury during operation. At the same time, maintenance should be carried out in a well ventilated environment to prevent inhalation of harmful gases.
In terms of tool usage, it is essential to choose appropriate tools and it is strictly prohibited to use damaged or unsuitable tools. When disassembling and installing components, it is necessary to strictly use a torque wrench according to the prescribed torque to avoid component damage or unstable installation caused by excessive or insufficient torque. For example, when disassembling and installing cylinder head bolts, follow the prescribed torque and sequence to ensure good sealing of the cylinder head.
The installation specifications for accessories cannot be ignored. Before installing new accessories, carefully check whether their model and specifications are consistent with the original accessories to ensure that the quality of the accessories is qualified. During installation, attention should be paid to cleaning the surface of the components, applying an appropriate amount of lubricating oil to ensure accurate installation position, and avoiding situations such as misalignment and missing installation. When installing piston rings, pay attention to the opening direction and clearance of the piston rings to ensure good sealing performance.

Daily maintenance and maintenance suggestions
（1） Regular maintenance plan
It is crucial to develop a scientific and reasonable regular maintenance plan to ensure that the Perkins 1.7 diesel engine always operates in good condition. When a new machine is first used and has accumulated 60 hours of operation, a comprehensive maintenance is required. At this time, it is necessary to replace the diesel filter element, engine oil filter element, and diesel engine oil in a timely manner. Timely replacement of these key components can effectively remove impurities from the fuel and engine oil, prevent them from causing wear and tear on the precision components inside the engine, and lay the foundation for the stable operation of the engine.
As the usage time increases, the diesel filter element, oil filter element, and diesel engine oil should be replaced again every 250 hours of operation to maintain a clean environment inside the engine. At the same time, according to the operating environment of the unit, when the working hours reach 300-600 hours, the air filter element needs to be replaced. When used in dusty environments, the frequency of replacing air filters should be appropriately increased to ensure that the air entering the engine is always clean and to avoid excessive wear of engine cylinders, pistons, and other components due to excessive air impurities.
If the diesel engine is not used frequently, maintenance work cannot be ignored. Every six months, it is necessary to replace the diesel engine oil to prevent it from deteriorating and losing its lubrication and protective properties due to prolonged standing.
（2） Correct usage and maintenance methods
Before starting the Perkins 1.7 diesel engine, a comprehensive and detailed inspection should be conducted. First, check the oil level in the oil pan, which should be maintained between the upper and lower marks on the dipstick to ensure that all moving parts of the engine have sufficient lubrication. Check the cooling system, fill it with cooling water, ensure that the engine can effectively dissipate heat during operation, and prevent overheating and damage. Also, check the fuel level in the fuel tank, turn on the fuel switch to allow diesel to flow to the fuel transfer pump, and remove air from the fuel system to avoid difficulty starting due to air entering the fuel system. At the same time, check if the battery is fully charged to ensure that the starter motor has enough power to drive the engine to start.
When starting, if the ambient temperature is low, machines with pre heat plugs can use a preheating start method. Turn the key switch to the "preheating" position and hold for 40-50 seconds to allow the preheating plug to preheat the combustion chamber, improving the atomization effect and combustion efficiency of the fuel. The starting time should not exceed 5 seconds each time to protect the starter motor and battery. If continuous startup is required, it should be stopped for 2 minutes before restarting. If the device cannot be started three times in a row, it is necessary to investigate the cause of the malfunction. Do not blindly start it multiple times to avoid damaging the equipment.
During the operation of a diesel engine, it is important to closely monitor various instrument parameters such as oil pressure, water temperature, and engine speed. Low oil pressure may indicate insufficient oil, oil pump failure, or oil circuit blockage, which can lead to poor engine lubrication and exacerbate component wear; If the water temperature is too high, it indicates that there is a problem with the engine's heat dissipation, which may be caused by cooling system failure, insufficient coolant, or loose fan belts. Prolonged high-temperature operation can cause deformation and damage to engine components; Abnormal engine speed may indicate uneven engine load, poor fuel supply, or governor malfunction. Once abnormal instrument parameters are found, the machine should be stopped immediately for inspection, and the fault should be eliminated before continuing to operate.
When the machine is stopped, it cannot be operated arbitrarily. Gradually reduce the load and speed of the diesel engine first, let the engine run at idle for 3-5 minutes, so that all components receive sufficient cooling and lubrication, and avoid overheating and damage to components or insufficient oil return due to sudden shutdown. Then turn off the fuel switch, cut off the fuel supply, and then turn off the power switch to complete the shutdown operation.
In daily maintenance, the inspection of oil cannot be ignored. Regularly check the quality and level of the engine oil, observe the color and viscosity of the oil. If the oil color turns black and the viscosity decreases, it indicates that the oil has deteriorated and needs to be replaced in a timely manner. At the same time, check the coolant level and concentration to ensure that the coolant has good anti freezing, anti boiling, and anti-corrosion properties. It is also necessary to check the quality of the fuel, avoid using inferior fuel, and prevent impurities and moisture in the fuel from damaging the fuel system.
The inspection and maintenance of filters are equally crucial. Regularly clean the filter element of the air filter, and use compressed air to blow outwards from the inside of the filter element to remove dust and impurities. If the filter element is found to be damaged or severely clogged, it should be replaced in a timely manner. For fuel filters and oil filters, they should also be replaced according to the prescribed time and mileage to ensure their filtering effect and provide clean fuel and oil for the engine.
