探秘珀金斯1.7柴油機配件
（一）常用配件大盤點
濾清器是保障發動機“呼吸”順暢與“飲食”清潔的關鍵防線。空氣濾清器能有效濾除空氣中的灰塵、雜質，確保進入發動機的空氣純凈，減少氣缸、活塞等部件的磨損。一旦空氣濾清器堵塞，發動機進氣量不足，會導致燃燒不充分，功率下降，油耗增加，就像人戴著堵塞的口罩呼吸，會感到憋悶難受。燃油濾清器則專注于過濾燃油中的雜質和水分，為噴油系統提供清潔的燃油，防止噴油嘴堵塞、磨損，保證發動機的燃油供給穩定，燃燒高效。機油濾清器負責過濾機油中的金屬碎屑、雜質等，維持機油的清潔度，讓機油能充分發揮潤滑、冷卻作用，保護發動機各運動部件。
皮帶在發動機中扮演著動力傳遞的重要角色。常見的有風扇皮帶、發電機皮帶等。風扇皮帶帶動風扇運轉，為發動機散熱，確保發動機在適宜的溫度下工作。若風扇皮帶松弛或斷裂，發動機散熱不良，會出現過熱現象，嚴重時可能導致發動機損壞。發電機皮帶則將發動機的動力傳遞給發電機，使發電機發電，為車輛的電氣系統提供電力。如果發電機皮帶故障，車輛的電池無法充電，電氣設備將無法正常工作。
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，保證發動機的正常壓縮比和燃燒效率。油底殼墊則防止機油泄漏，維持發動機潤滑系統的正常工作。油封用于密封旋轉部件，防止機油泄漏，保證發動機的密封性。這些密封件和墊片雖小，卻對發動機的性能和可靠性有著重要影響。
（二）關鍵大修配件解析
活塞堪稱發動機的“心臟起搏器”，在燃燒室內，柴油燃燒產生的高溫高壓氣體推動活塞向下運動，帶動曲軸轉動，實現熱能到機械能的轉化，驅動設備運行。同時，活塞與氣缸壁之間通過活塞環保持良好的密封性，防止氣缸內氣體泄漏，保證發動機的正常工作壓力。活塞的材質和結構設計需具備足夠的強度和剛度，以承受巨大的壓力和沖擊力。
缸套作為活塞運動的“軌道”，直接與高溫高壓的燃氣接觸，承受著高溫、高壓和摩擦的考驗。它不僅為活塞提供導向，還能幫助活塞散熱，保證活塞的正常工作。優質的缸套材質和精密的加工工藝，能確保缸套的耐磨性和尺寸精度，延長發動機的使用壽命。
曲軸是發動機的“動力輸出軸”，它將活塞的往復直線運動轉化為旋轉運動，輸出動力。曲軸在工作過程中承受著巨大的扭矩和彎曲力，因此需要具備極高的強度和剛度。曲軸的加工精度和動平衡性能對發動機的平穩運行至關重要，哪怕是微小的偏差，都可能導致發動機振動加劇、噪音增大，甚至引發嚴重故障。

（三）原廠與副廠配件的抉擇
原廠配件由珀金斯公司直接生產或授權生產，嚴格遵循發動機的設計規格和制造標準。其質量經過了層層嚴格的把控和檢測，在性能上與發動機完美匹配，能確保發動機發揮出最佳性能，提供更高的安全保障和更長的使用壽命。并且，原廠配件通常能獲得廠家的技術支持和完善的售后服務保障，如質量保修、技術指導等。然而，原廠配件的價格相對較高，供應渠道有時較為有限，可能需要等待較長時間才能到貨。
副廠配件由第三方廠家生產，沒有得到珀金斯公司的授權。部分副廠配件在質量和性能上也能達到一定標準，且價格相對較低，能為用戶節省成本。但副廠配件市場魚龍混雜，部分產品的生產標準和材料選擇可能不符合發動機的規格要求，存在質量參差不齊的問題。這些劣質副廠配件可能無法完全適應發動機的工作環境，導致性能下降、故障頻發，甚至對發動機造成嚴重損壞，而且在售后服務方面也往往難以得到有效保障。
在選擇配件時，如果追求發動機的最佳性能、可靠性和長期穩定運行，對設備的使用安全有較高要求，那么原廠配件無疑是最佳選擇。若預算有限，且能確保選擇的副廠配件質量可靠、來源正規，也可考慮副廠配件，但需謹慎篩選，密切關注使用效果。

珀金斯1.7柴油機維修技術深度剖析
（一）常見故障診斷方法
當珀金斯1.7柴油機出現啟動困難的情況時，我們可以從多個方面進行初步診斷。先聽聲音，啟動時若起動機運轉正常，但發動機無著火跡象，可能是燃油系統故障；若有“噠噠”聲，可能是氣門間隙過大或啟動機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致冷卻水進入氣缸；冒黑煙則可能是燃燒不充分，空氣濾清器堵塞或噴油過多。還需檢查儀表，查看機油壓力、水溫等儀表讀數，若機油壓力過低，可能影響發動機啟動。
若是發動機功率不足，聽聲音時，若發動機運轉聲音沉悶，可能是負荷過大或內部有故障。看排氣，冒黑煙且動力不足，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。檢查儀表，關注機油溫度、冷卻液溫度，若過高，ECU可能進入過熱保護模式，限制發動機功率。
對于發動機異常響聲，不同的聲音往往暗示著不同的故障。若是清脆的“當當”聲，可能是活塞敲缸，原因可能是活塞與氣缸壁間隙過大；若是連續的“嗡嗡”聲，可能是軸承磨損，軸承間隙過大；若是尖銳的“吱吱”聲，可能是皮帶打滑，皮帶過松或磨損嚴重。

（二）針對性維修策略
針對啟動困難，若確定是燃油系統問題，比如燃油濾清器堵塞，需及時更換濾芯；噴油器故障，如噴油嘴積碳、噴油壓力不足，可進行清洗、研磨或更換噴油器。若是啟動電機故障，出現碳刷磨損、轉子卡滯等情況，要維修或更換啟動電機。
當發動機功率不足時，如果是空氣濾清器不清潔，增加了阻力，導致空氣流量減少，充氣效率下降，應定期清洗柴油空氣濾清器芯子，清除積塵，必要時更換濾芯。若是供油提前角過大或過小，造成油泵噴油時間過早或過晚，使燃燒過程不是處于最佳狀態，應檢查噴油傳動軸接合器螺釘是否松動，如果松動，則應重新按照要求調整供油提前角，并擰緊螺釘。要是活塞與缸套拉傷，造成摩擦損失增大，發動機自身的機械損失增大，壓縮比減小，著火困難或燃燒不充分，此時，應更換缸套、活塞和活塞環。
面對發動機異常響聲，若因氣門間隙過大產生異響，可依據維修手冊，使用塞尺等工具，精準調整氣門間隙。要是噴油提前角過大導致的異常響聲，需重新校準噴油提前角，確保噴油時機精準。如果是柴油標號不符合標準引發的問題，應更換符合要求的柴油，保證燃油質量。
（三）維修中的注意事項
維修過程中，安全操作至關重要。維修前，必須關閉柴油機，等待其完全冷卻，防止燙傷。維修人員要佩戴好防護手套、護目鏡等裝備，避免在操作過程中受傷。同時，要在通風良好的環境中進行維修，防止吸入有害氣體。
在工具使用方面，務必選用合適的工具，嚴禁使用損壞或不合適的工具。拆卸和安裝部件時，要嚴格按照規定的扭矩使用扭力扳手，避免因扭矩過大或過小導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，要按照規定的扭矩和順序進行操作，確保氣缸蓋密封良好。
配件安裝規范同樣不可忽視。安裝新配件前，要仔細檢查其型號、規格是否與原配件一致，確保配件質量合格。安裝時，要注意清潔部件表面，涂抹適量的潤滑油，保證安裝位置準確，避免出現錯位、漏裝等情況。像安裝活塞環時，要注意活塞環的開口方向和間隙，確保活塞環的密封性能良好。

日常保養與維護建議
（一）定期保養計劃
為了確保珀金斯1.7柴油機始終保持良好的運行狀態，制定一份科學合理的定期保養計劃至關重要。在新機初次使用時，當累計工作達到60小時，就需要進行一次全面的保養。此時，要及時更換柴油濾芯、機油濾芯和柴油機油，這些關鍵部件的及時更換，能有效清除燃油、機油中的雜質，防止它們對發動機內部精密部件造成磨損，為發動機的穩定運行奠定基礎。
隨著使用時間的增加，在后續的使用過程中，每工作250小時，便要再次更換柴油濾芯、機油濾芯和柴油機油，保持發動機內部的清潔環境。同時，根據機組的使用環境，當工作時長達到300-600小時時，需對空氣濾芯進行更換。在灰塵較多的環境中使用，空氣濾芯的更換頻率應適當提高，確保進入發動機的空氣始終保持清潔，避免因空氣雜質過多導致發動機氣缸、活塞等部件過度磨損。
如果柴油機不經常使用，也不能忽視保養工作。每隔半年，就需要更換一次柴油機油，防止機油因長時間靜置而變質，失去應有的潤滑和保護性能。
（二）正確使用與維護方法
在啟動珀金斯1.7柴油機之前，要進行全面細致的檢查。先查看油底殼中的機油液位，應保持在油標尺上、下標記之間，確保發動機各運動部件有足夠的潤滑。檢查冷卻系統，加滿冷卻水，保證發動機在運行過程中能夠有效散熱，防止過熱損壞。還要檢查燃油箱中的存油量，打開燃油開關，使柴油流向輸油泵，并排除燃油系統內的空氣，避免因空氣進入燃油系統導致啟動困難。同時，檢查蓄電池充電是否充足，確保啟動電機有足夠的電力驅動發動機啟動。
啟動時，若環境溫度較低，帶預熱塞的機器可采用預熱起動方式。將鑰匙開關轉至“預熱”位置，停留40-50秒，讓預熱塞對燃燒室進行預熱，提高燃油的霧化效果和燃燒效率。每次啟動時間不應超過5秒，以保護啟動電機和蓄電池。如需連續啟動，應停歇2分鐘后再行起動。如果連續三次不能起動，就需要排查故障原因，切勿盲目多次啟動，以免損壞設備。
柴油機運行過程中，要密切關注各項儀表參數，如機油壓力、水溫、轉速等。機油壓力過低，可能意味著機油不足、機油泵故障或油路堵塞，會導致發動機潤滑不良，加劇部件磨損；水溫過高，表明發動機散熱出現問題，可能是冷卻系統故障、冷卻液不足或風扇皮帶松弛等原因引起，長時間高溫運行會使發動機零部件變形、損壞；轉速異常則可能暗示著發動機負荷不均、燃油供應不暢或調速器故障等。一旦發現儀表參數異常，應立即停機檢查，排除故障后再繼續運行。
停機時，也不能隨意操作。先逐漸降低柴油機的負荷和轉速，讓發動機在怠速狀態下運行3-5分鐘，使各部件得到充分的冷卻和潤滑，避免因突然停機導致零部件過熱損壞或機油未能充分回流。然后關閉燃油開關，切斷燃油供應，再關閉電源開關，完成停機操作。
在日常維護中，對油液的檢查不容忽視。定期檢查機油的質量和液位，觀察機油的顏色和粘度，若機油顏色變黑、粘度下降，說明機油已變質，需要及時更換。同時，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。還要檢查燃油的質量，避免使用劣質燃油，防止燃油中的雜質和水分對燃油系統造成損害。
濾清器的檢查和維護同樣關鍵。定期清理空氣濾清器的濾芯，可使用壓縮空氣從濾芯內部向外吹，清除灰塵和雜質。若發現濾芯破損或堵塞嚴重，應及時更換。對于燃油濾清器和機油濾清器，也要按照規定的時間和里程進行更換，保證其過濾效果，為發動機提供清潔的燃油和機油。

Since British entrepreneur Frank Perkins founded Perkins in Peterborough in 1932, after nearly a century of trials and tribulations and technological accumulation, Perkins diesel engines have occupied a pivotal position in the global engine market with their outstanding performance, stable reliability, and innovative technological strength.
This diesel engine is widely used in various fields such as industry, agriculture, shipbuilding, and power generation, providing a continuous source of powerful power for numerous devices. In industrial production, industries such as petroleum, chemical, pharmaceutical, and food processing require extremely high stability and reliability of equipment. The Perkins 1.7 diesel engine, with its high efficiency, reliability, and environmental friendliness, injects powerful power support into the production equipment of these industries, ensuring stable and efficient production processes. For example, in oil extraction, the Perkins 1.7 diesel engine drives the drilling equipment, and its stable power output ensures the smooth progress of the extraction work.
In the field of agricultural machinery, the efficient operation of tractors, harvesters, irrigation equipment and other agricultural machinery also relies on the stable power output of Perkins 1.7 diesel engines. Its efficient, reliable, and environmentally friendly characteristics enable agricultural machinery to operate stably in the fields, greatly improving agricultural production efficiency while reducing environmental pollution and contributing to the modernization of agriculture. Just like a large combine harvester, driven by a Perkins 1.7 diesel engine, it can quickly and stably complete harvesting tasks.
In the field of ships, whether it is cargo ships sailing on the waves, passenger ships carrying passengers, or fishing boats going out to sea, Perkins 1.7 diesel engines can provide reliable power support to ensure safe navigation on the water surface and improve transportation efficiency. Imagine an ocean going cargo ship sailing on the vast sea, with the Perkins 1.7 diesel engine as its "heart", steadily beating and outputting powerful power.
In addition, in the fields of power generation and energy, the efficient and stable characteristics of Perkins 1.7 diesel engines enable power generation equipment to continuously and stably output electricity, meeting the needs of industrial, commercial, and residential electricity, and providing solid power security for the normal operation of society. In some emergency power generation scenarios, the Perkins 1.7 diesel engine driven generator set can quickly start and provide power to important places such as hospitals and communication base stations.
It can be said that the Perkins 1.7 diesel engine has become the core power source for stable operation of many devices, and its importance is self-evident. Once this critical power component malfunctions, related equipment may come to a standstill, causing inconvenience and losses to production and daily life. Therefore, it is particularly important to have a deep understanding of Perkins 1.7 diesel engine components and master their maintenance technical support to ensure the normal operation of equipment, improve production efficiency, and reduce operating costs.
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.
