关键配件大盘点
滤清器类
柴油滤清器是燃油系统的忠诚卫士，肩负着过滤柴油中杂质与水分的重任，确保进入发动机的柴油纯净清洁，维持燃油系统的顺畅运行。要知道，国内柴油的含硫量相对较高，倘若没有柴油滤清器把关，硫元素会与水发生反应生成硫酸，进而腐蚀发动机内部零件。一旦柴油滤清器的滤芯过脏，无法保障燃油进入发动机缸内燃烧时的清洁度，汽车动力就会严重下滑，还可能影响部分零件的使用寿命，届时维修成本相当高昂。
空气滤清器负责过滤进入发动机的空气中的杂质和颗粒物，防止灰尘和颗粒物进入气缸，维持发动机的正常运转。要是使用了非原厂的空气滤清器，过滤效果不佳，灰尘等杂质就会进入气缸，加剧气缸磨损，还可能导致活塞环损坏，影响发动机性能与寿命。
机油滤清器则承担着过滤机油中杂质和颗粒物的任务，保持机油的清洁度，避免机油中的杂质对发动机零件造成磨损和损坏。若使用非原厂的机油滤清器，可能引发机油污染、机油压力不足等问题，同样会对发动机性能产生负面影响。所以，为了确保珀金斯804柴油机的正常运行，务必使用原厂滤清器。原厂滤清器经过严格的质量检测和认证，在设计、制造和测试过程中充分考虑了发动机的工作原理和性能要求，能够与发动机完美匹配，有效提高发动机的燃烧效率和动力输出，降低油耗和排放。

活塞与活塞环
活塞在发动机中扮演着至关重要的角色，它在气缸内做往复直线运动，通过连杆将动力传递给曲轴，进而实现发动机的能量转换。而活塞环作为柴油机中关键的密封元件，有着多重重要作用。它能保证活塞与气缸之间的密封性，防止燃烧过程中产生的气体和杂质进入曲轴箱，将气体泄漏量控制在最低限度，从而提高热效率。漏气不仅会使发动机动力下降，还会导致机油变质。活塞环还能起到导热油冷却的作用，在燃烧过程中，高温高压的燃气会通过活塞环的间隙对活塞进行冷却，同时活塞环上的油槽可以将润滑油带到燃烧室表面，形成油膜，降低燃气与活塞表面的直接接触，减少热量传递，提高活塞的使用寿命。此外，活塞环表面的锯齿状结构有助于将气缸壁上多余的润滑油刮下并带入曲轴箱，避免润滑油过多进入燃烧室造成浪费，同时刮去燃烧过程中产生的炭渣和其他杂质，保持气缸内的清洁。
当活塞和活塞环出现磨损或损坏时，发动机的性能会受到显著影响。可能会导致发动机漏气，使动力下降、油耗增加；还可能引发发动机抖动、启动困难等问题，严重时甚至会造成发动机无法正常工作。

气门组件
气门组件在发动机的进排气过程中起着关键的控制作用。进气门负责将新鲜的空气或空气与燃油的混合气引入气缸，排气门则负责将燃烧后的废气排出气缸，它们按照精确的时序开启和关闭，以确保发动机的正常工作循环。气门的密封性对发动机性能有着至关重要的影响。如果气门密封不严，会导致气体泄漏，使发动机的动力输出下降，加速无力，尤其是在高速行驶时表现更为明显。气门密封不严还会导致燃油燃烧不充分，增加油耗，同时使尾气排放超标，污染环境。长期的气体泄漏还会加剧气门和气门座的磨损，缩短发动机的使用寿命。
为了确保气门的密封性，高质量的气门材料和精密的加工工艺是关键，它们能够保证气门的尺寸精度和表面光洁度，减少气门与气门座之间的间隙。气门座的研磨也十分重要，精细研磨可以使气门座与气门之间达到良好的贴合，形成有效的密封面。定期维护和保养同样不可或缺，及时更换磨损的气门油封，防止机油进入气门室影响气门密封效果；正确安装和调整气门弹簧，避免因气门弹簧弹力不足或安装不当导致气门关闭不严。

维修技术深度剖析
常见故障诊断
在珀金斯804柴油机的长期使用过程中，难免会遭遇一些常见故障。启动困难是较为常见的问题之一，其原因往往是多方面的。从燃油系统来看，低压油道若发生堵塞，油管接头松动导致漏油，高压油管内混入空气，喷油器技术状态不佳，喷油正时角出现偏差，都可能影响燃油的正常供应和喷射，从而造成启动困难。从启动器角度分析，电源问题，如蓄电池电量不足；电磁开关接触不良，开启电机换向器与电刷接触不良，起动机传动机构离合器打滑等，都会使起动机无法正常工作，难以带动柴油机启动。气缸压缩压力欠缺也是关键因素，气缸垫损坏漏气、气门关闭不紧漏气、活塞缸筒磨损漏气，都会导致气缸内无法形成足够的压缩压力，使柴油难以被点燃，进而导致启动困难。
动力不足也是柴油机常见故障。这可能是由燃烧室密封不良、供油量不足、喷油器雾化不良、供气不足、供油正时调整不当等原因，造成燃油不完全燃烧，无法充分释放能量来驱动柴油机。零部件磨损过大、润滑不良、冷却不良、安装不当等，也会使柴油机本身摩擦损失的功率过大，降低了输出功率，导致动力不足。
柴油机在运行时出现异常声响也不容忽视。活塞顶部若有小垫片、螺钉等异物通过进气管或安装喷油器的孔落入气缸，在活塞运动到上止点附近时就会撞击活塞顶部，发出异常噪音。连杆衬套严重磨损或损坏，会导致连杆轴承间隙过大，产生异常响声。气门间隙过大，在柴油机加速时会发出“当当当”的声音；气缸漏气时，运转过程中会发出“咳咳咳”的声音。

维修步骤与技巧
当遇到喷油器故障时，检修工作需要细致且专业。如果喷油器出现喷油雾化不良的情况，可能是喷油压力过低、弹簧端面磨损或弹簧弹力下降导致的。此时，需要检查喷油压力，若压力不足，可通过调整调压螺钉来提高喷油压力；若弹簧有问题，则需更换新的弹簧。要是喷油器密封失效，出现排白烟并伴有放炮声，多是针阀体的密封锥面受到针阀频繁冲击和磨料磨损，出现划痕或点蚀，配合锥面接触宽度增加所致。这时，需拆开喷油器，对密封锥面进行研磨修复，若磨损严重则需更换针阀偶件。若针阀卡死无法喷油，可能是柴油中的水分或酸性物质过量使针阀锈蚀，或者气缸内可燃混合气窜入配合面形成积炭导致的。可将喷油器放入柴油中加热，然后尝试拔出针阀，若针阀损坏则需更换新的喷油嘴偶件。
对于启动困难的故障，如果是燃油系统中有空气，可通过松开油管接头，排净空气来解决；若喷油器喷油时间过早或过晚，就需要重新调整供油提前角，确保喷油时间准确。要是动力不足是因为空气滤清器堵塞，应及时清洁或更换空气滤清器滤芯，保证进气顺畅；若喷油器雾化不良，可清洗喷油器，必要时更换喷油嘴偶件，以改善燃油雾化效果。

维修后的调试与检测
维修后的调试与检测是确保珀金斯804柴油机恢复正常性能的关键环节。调试能够使发动机的各项参数达到最佳状态，检测则可以及时发现潜在问题，保证发动机的可靠性和稳定性。
常用的检测方法包括压缩压力测试，使用专业压缩压力测试仪测量每个气缸的压缩压力，并与标准值对比，确保压力正常。漏气测试也很重要，向气缸注入压缩空气，观察有无漏气现象，以此判断气缸的密封性能。启动测试同样不可或缺，通过观察柴油机启动是否顺畅，运转是否平稳，有无异常噪音和振动，来检验启动性能。负载测试则是逐渐增加负载，检查柴油机在不同负载下的动力输出、燃油消耗和排气情况，确保其在实际工作中的性能符合要求。还需对润滑系统和冷却系统进行检验，检查润滑油的压力、流量、油品温度和粘度，以及水泵、散热器、冷却液等部件是否正常，有无漏油渗油、漏水渗水现象。

Key component inventory
Filter class
Diesel filters are the loyal guardians of the fuel system, responsible for filtering impurities and moisture from diesel, ensuring that the diesel entering the engine is pure and clean, and maintaining the smooth operation of the fuel system. You should know that the sulfur content of domestic diesel is relatively high. If there is no diesel filter to control it, the sulfur element will react with water to generate sulfuric acid, which will corrode the internal parts of the engine. Once the filter element of the diesel filter is too dirty, it cannot guarantee the cleanliness of the fuel when it enters the engine cylinder for combustion, and the power of the car will seriously decline. It may also affect the service life of some parts, and the maintenance cost will be quite high at that time.
The air filter is responsible for filtering impurities and particulate matter from the air entering the engine, preventing dust and particulate matter from entering the cylinder, and maintaining the normal operation of the engine. If non original air filters are used, the filtering effect will be poor, and dust and other impurities will enter the cylinder, exacerbating cylinder wear and possibly causing damage to the piston rings, affecting engine performance and lifespan.
The oil filter is responsible for filtering impurities and particulate matter from the engine oil, maintaining its cleanliness, and preventing impurities from causing wear and damage to engine parts. If non original oil filters are used, it may cause problems such as oil pollution and insufficient oil pressure, which can also have a negative impact on engine performance. So, in order to ensure the normal operation of the Perkins 804 diesel engine, it is necessary to use the original factory filter. The original filter has undergone strict quality testing and certification, fully considering the working principle and performance requirements of the engine in the design, manufacturing, and testing process. It can be perfectly matched with the engine, effectively improving the combustion efficiency and power output of the engine, reducing fuel consumption and emissions.
Pistons and piston rings
The piston plays a crucial role in the engine, as it performs reciprocating linear motion within the cylinder and transmits power to the crankshaft through the connecting rod, thereby achieving energy conversion in the engine. As a key sealing component in diesel engines, piston rings play multiple important roles. It can ensure the sealing between the piston and cylinder, prevent gases and impurities generated during combustion from entering the crankcase, control gas leakage to the minimum, and thus improve thermal efficiency. Leakage not only reduces engine power, but also causes oil deterioration. The piston ring can also play a role in cooling the heat transfer oil. During the combustion process, high-temperature and high-pressure gas will cool the piston through the gap of the piston ring. At the same time, the oil groove on the piston ring can bring lubricating oil to the surface of the combustion chamber, forming an oil film, reducing the direct contact between the gas and the piston surface, reducing heat transfer, and improving the service life of the piston. In addition, the serrated structure on the surface of the piston ring helps to scrape off excess lubricating oil from the cylinder wall and bring it into the crankcase, avoiding waste caused by excessive lubricating oil entering the combustion chamber. At the same time, it scrapes off carbon slag and other impurities generated during the combustion process, keeping the cylinder clean.
When the piston and piston ring are worn or damaged, the performance of the engine will be significantly affected. May cause engine leakage, resulting in decreased power and increased fuel consumption; It may also cause engine shaking, difficulty starting, and in severe cases, even cause the engine to malfunction.
Valve components
Valve components play a critical control role in the intake and exhaust processes of the engine. The intake valve is responsible for introducing fresh air or a mixture of air and fuel into the cylinder, while the exhaust valve is responsible for discharging the burned exhaust gas from the cylinder. They open and close in precise timing to ensure the normal working cycle of the engine. The sealing performance of valves has a crucial impact on engine performance. If the valve seal is not tight, it will cause gas leakage, resulting in a decrease in engine power output and weak acceleration, especially at high speeds. Poor valve sealing can also lead to insufficient fuel combustion, increased fuel consumption, and excessive exhaust emissions, polluting the environment. Long term gas leakage can also exacerbate the wear of valves and valve seats, shortening the service life of the engine.
In order to ensure the sealing of the valve, high-quality valve materials and precise machining processes are key, which can ensure the dimensional accuracy and surface smoothness of the valve, and reduce the gap between the valve and the valve seat. Grinding the valve seat is also very important. Fine grinding can achieve a good fit between the valve seat and the valve, forming an effective sealing surface. Regular maintenance and upkeep are equally essential. Timely replacement of worn valve oil seals is necessary to prevent oil from entering the valve chamber and affecting the valve sealing effect; Correctly install and adjust the valve spring to avoid loose valve closure due to insufficient elasticity or improper installation of the valve spring.
In depth analysis of maintenance technology
Common fault diagnosis
During the long-term use of Perkins 804 diesel engine, it is inevitable to encounter some common faults. Startup difficulty is one of the more common problems, and its reasons are often multifaceted. From the perspective of the fuel system, if the low-pressure oil passage is blocked, the oil pipe joint becomes loose, causing oil leakage, air is mixed into the high-pressure oil pipe, the technical condition of the fuel injector is poor, and the injection timing angle deviates, all of these may affect the normal supply and injection of fuel, resulting in difficulty in starting. From the perspective of the starter, power issues such as insufficient battery power; Poor contact between the electromagnetic switch, poor contact between the motor commutator and the brush, and slipping of the clutch in the starter transmission mechanism can all prevent the starter from working properly and make it difficult to start the diesel engine. Insufficient cylinder compression pressure is also a key factor. Damage to the cylinder gasket, loose valve closure, and worn piston cylinder can all lead to insufficient compression pressure in the cylinder, making it difficult to ignite diesel and resulting in difficulty starting.
Insufficient power is also a common fault of diesel engines. This may be caused by poor sealing of the combustion chamber, insufficient fuel supply, poor atomization of the fuel injector, insufficient gas supply, improper adjustment of fuel supply timing, etc., resulting in incomplete combustion of fuel and inability to fully release energy to drive the diesel engine. Excessive wear of components, poor lubrication, poor cooling, improper installation, etc. can also cause excessive power loss due to friction in the diesel engine itself, reducing output power and leading to insufficient power.
Abnormal noises made by diesel engines during operation cannot be ignored. If there are foreign objects such as small gaskets or screws on the top of the piston that fall into the cylinder through the intake pipe or the hole where the fuel injector is installed, they will collide with the top of the piston when it reaches the top dead center, making abnormal noise. Severe wear or damage to the connecting rod bushing can cause excessive clearance between the connecting rod bearings, resulting in abnormal noise. If the valve clearance is too large, it will make a "dang dang" sound when the diesel engine accelerates; When the cylinder leaks, it will make a "cough cough cough" sound during operation.
Repair steps and techniques
When encountering fuel injector faults, maintenance work needs to be meticulous and professional. If the fuel injector has poor fuel atomization, it may be caused by low fuel injection pressure, worn spring end face, or decreased spring elasticity. At this point, it is necessary to check the fuel injection pressure. If the pressure is insufficient, the fuel injection pressure can be increased by adjusting the pressure regulating screw; If there is a problem with the spring, a new spring needs to be replaced. If the seal of the fuel injector fails, white smoke is emitted and accompanied by a blasting sound, it is mostly caused by frequent impact and abrasive wear of the sealing cone surface of the needle valve body, resulting in scratches or pitting, and an increase in the contact width of the cone surface. At this point, the fuel injector needs to be disassembled and the sealing cone surface needs to be ground and repaired. If the wear is severe, the needle valve assembly needs to be replaced. If the needle valve is stuck and unable to inject fuel, it may be due to excessive moisture or acidic substances in the diesel causing the needle valve to rust, or the combustible mixture in the cylinder entering the mating surface and forming carbon deposits. You can heat the fuel injector by placing it in diesel and then try to remove the needle valve. If the needle valve is damaged, you need to replace it with a new fuel injector.
For start-up difficulties, if there is air in the fuel system, it can be solved by loosening the oil pipe joint and draining the air; If the fuel injector sprays too early or too late, it is necessary to readjust the fuel supply advance angle to ensure accurate injection time. If the lack of power is due to a clogged air filter, the air filter element should be cleaned or replaced in a timely manner to ensure smooth air intake; If the fuel injector has poor atomization, the injector can be cleaned and the fuel injector fittings can be replaced if necessary to improve the fuel atomization effect.
Debugging and testing after maintenance
The debugging and testing after maintenance are key steps to ensure the normal performance of the Perkins 804 diesel engine is restored. Debugging can achieve the optimal state of various parameters of the engine, while testing can promptly detect potential problems, ensuring the reliability and stability of the engine.
The commonly used detection methods include compression pressure testing, using a professional compression pressure tester to measure the compression pressure of each cylinder and comparing it with the standard value to ensure that the pressure is normal. Leakage testing is also important. Inject compressed air into the cylinder and observe for any leakage to determine the sealing performance of the cylinder. The start-up test is also indispensable, by observing whether the diesel engine starts smoothly, runs smoothly, and whether there are any abnormal noises and vibrations, to test the start-up performance. The load test gradually increases the load to check the power output, fuel consumption, and exhaust situation of the diesel engine under different loads, ensuring that its performance meets the requirements in actual operation. It is also necessary to inspect the lubrication system and cooling system, checking the pressure, flow rate, oil temperature, and viscosity of the lubricating oil, as well as whether the components such as the water pump, radiator, and coolant are normal, and whether there is any oil or water leakage.

From the packaging perspective, regular accessory packaging is standardized, with uniform standard specifications and exquisite printing; The packaging printing of counterfeit products is relatively blurry and rough, which is prone to defects. Carefully observe the appearance of the accessories. Poor quality products processed by unscrupulous merchants, even if they appear good in appearance, may have problems such as cracks, sand holes, slag inclusions, burrs, or protrusions due to poor manufacturing processes. Different models of Perkins diesel engines use different accessories, and the same model may also have differences due to factors such as production year and emission standards. When purchasing, it is important to pay attention to the applicability and compatibility of the accessories, confirm the engine model and the name, number, and other information of the required accessories, and ensure that the accessories can be installed correctly and function properly. Attention should also be paid to market price fluctuations, as accessories with excessively low prices are likely to be counterfeit and inferior products.
