富康电喷发动机的机油蒸气由曲轴箱废气管流出，进入空滤器，再进入进气室，在发动机中燃烧后，可以减少直接排放机油蒸气对大气环境的污染。由于机油蒸气进入进气系统时，温度下降，机油蒸气遇冷凝结，对汽车进气系统造成污染，比如进气压力传感器进油，燃油压调节器脏污，怠速旋转阀脏污，真空管脏污等。这是FK电喷发动机的常见病多发病。 　　有的出租车就把机油蒸汽再燃烧去掉，直接排放到大气中，这种损人利己的行为是错误的。同时，这种做法也不利曲轴箱内部循环换气。 　　进气压力传感器进油，使ECU得不到发动机进气室正确的压力数据，它就不能给出正确的控制动作，发动机工作不正常。最明显的现象是行车中容易熄火，怠速低、不稳定。更换进口的压力传感器，要400元。 　　怠速旋转阀脏污，造成发动机怠速不稳，容易熄火。 　　燃油压调节器脏污，使ECU得不到燃油与进气室压强差，造成燃油喷射压力偏高，供油过多导致混合气偏浓，从而出现加速不良，怠速高、不稳定。 　　对发动机怠速阀、真空管、节气门和曲轴废气管的清洗，是富康TU5JP/K和TU3JP/K电喷发动机的常见保养，可以自己做。做好了这件DIY工作，一些常见的发动机故障就不会出现，还可以丰富用车的层次，你不妨试试。 　　一、怠速阀清洗 　　怠速阀在发动机的后部，它一头通过管道接在空滤上，另一头接在发动机进气室，是由双线圈控制的截止阀，有4个通量不同的导通位置。当它导通时，发动机直接从空滤经怠速阀得到进气，保持发动机怠速运转。由于长期使用，难免有积垢产生，造成怠速阀不通畅，怠速不稳定，或行车中熄火。 　　建议每季度清洗一次，可以DIY。方法如下： 　　1、发动机处于熄火，稍凉，揭开发动机盖，撑好。准备化油器清洗剂一听，塑料签，质量好的纸巾。 　　2、怠速阀在发动机后部，应当站在右轮一侧，先拔掉怠速阀上的驱动线路插头，注意插头的方向，以便正确恢复。不要用蛮力，先把钢丝卡子撬掉，轻轻拔就行。 　　3、用六角扳手松开两个内六角螺钉，卸下怠速阀，用化油器清洗剂清洗，并用干净纸巾将里面的积垢去除，塑料签可以去除手指不能深入的地方之积垢。如果有皮老虎或压缩空气源，可以吹吹怠速阀。 清洗完成后，摇动怠速阀，感受它的柱面阀体是否运动自如。如果有滞卡现象，说明还没有清洗干净，应当给阀体注入清洗剂，再摇晃，反复几次，直到清洗干净为止。 　　4、按照拆开相反顺序，保持清洁，把怠速阀安装好，正确插好怠速阀上的驱动线路插头。启动发动机试试。 　　二、清洗真空管 　　从发动机进气室有一根直径约10mm的橡胶管，通过一个三通连接燃油调节器和进气压力传感器，进气压力传感器在发动机仓右前部。RPC新自由人、RLC等使用TU3JP/K发动机，真空管在进入压力传感器之前，要通过一个白色半透明的小塑料壶，我认为它是为了防止机油蒸汽污染压力传感器而设置的，不要跳过它直接连接压力传感器。而TU5JP/K发动机的真空管直接连接压力传感器，没有沉积机油的塑料壶，因此，TU5JP/K发动机的压力传感器更容易被机油蒸气污染。 　　DIY清洗很容易，方法是： 　　1、把真空管都拔下来，用一根80cm长的细钢丝，钩住一个大小适当的干净布条，从真空管中拉过，把机油擦掉。注意，不要伤着橡胶管，也不能让布的纤维遗留在管道中，可以用压缩空气吹吹。 　　2、用化油器清洗剂清洗压力传感器，用纸巾和小塑料签小心擦拭干净。白色半透明的小塑料壶也可取下，用纸巾擦干净，保证两个出头管畅通。 　　3、再看看燃油调节器与真空管连接处是否被污染，请用纸巾和小塑料签小心擦拭干净。 　　4、按照原来连接的方式，保持清洁，把所有真空管插到位，不能漏气。 　　5、启动发动机，看看怠速运行是否稳定。如果不稳，一般是压力传感器的真空管没有插好，或漏气或不通。不必紧张，熄火后，认真检查一遍，重新插好即可。 　　三、清洗节气门 　　由于长期使用，节气门也会积垢，影响节气门开闭，造成发动机不能正常工作。建议，在清洁空滤时，检查节气门筒内是否有积垢，如果有积垢，可以使用化油器清洗剂清洗。 　　方法是（假设空滤已经拆开）： 　　1、用一字起子松开空滤与节气门体的金属卡子的紧固螺钉，使空滤顶盖与节气门体分离。 　　2、保持节气门处于关闭状态，将化油器清洗剂喷到门周围，再用纸巾和小塑料签小心擦拭干净。 　　3、用手来回掰动节气门扇形*作盘，看看节气门是否擦干净、是否能开闭自如。再把空滤与节气门体接上，要接到位保证密封，旋紧金属卡子的螺钉。 　　4、注意事项：自动档车不要拔掉节气门位置传感器插头，它在节气门体上，否则，需要使用仪器，对油门踏板位置重新初始化；注意不要把化油器清洗剂喷到节气门体的空滤密封橡胶圈上，它会腐蚀橡胶圈，影响密封性。 　　上述清洗节气门体属于部份清洗，要完整清洗，必须拆掉油门拉线，把节气门体从发动机进气室上xx拆下来，用化油器清洗剂清洗。比较麻烦，建议，到维修站做。特别是自动档，节气门体拆下后，要使用专用仪器初始化油门踏板位置，自己不能做。 　　四、清洗曲轴箱废气管和过滤片的方法 　　每月定期清洗曲轴箱废气管和过滤片，能够减少机油废气对节气门、压力传感器真空管、汽油压力调节器真空管的污染。这个定期保养，DIY很容易，建议自己搞。具体的*作方法： 　　1、热车熄火后，待发动机稍凉，揭开发动机盖，撑好。 　　2、准备质量好的纸巾，和一听“化油器清洗剂”。 　　3、站在机舱左侧的左前轮边，左手抓住废气橡胶管，要靠近空滤。右手握拳，打击左手背。废气橡胶管应当与空滤脱开。左手把住废气橡胶管冲上，不然，废机油会流出来，滴到机舱内。 　　4、拿出废气过滤片，用化油器清洗剂冲洗干净，放在清洁纸巾上。 　　5、用纸巾把废气管端的塑料接头的机油xx干净，同样把空滤接头的的机油xx干净。 　　6、把废气过滤片放入废气管端的塑料接头内，使点劲，使废气管与空滤吻合好。

Beverly EFI engine crankcase oil vapor from the exhaust pipe out into the air filter, re-entry into the chamber, after combustion in the engine can reduce the direct discharge of oil vapor on the atmospheric environment pollution. As the oil vapor into the intake system, the temperature dropped, the oil vapor condenses when cooled, the automobile air intake system cause pollution, such as inlet pressure sensor into the oil, fuel pressure regulator dirty, dirty idle rotary valve, vacuum tube dirty and so on. This is a common disease frequently-occurring FK EFI engine. Some took a taxi to remove the oil burning steam and then directly discharged into the atmosphere, this selfish behavior is wrong. At the same time, this inner loop is also detrimental to the crankcase ventilation. Inlet pressure sensor into the oil, not the engine ECU into the right chamber pressure data, it can not give the correct control action, the engine does not work correctly. The most obvious phenomenon is easy to stall in traffic, idling low and unstable. Pressure sensor to replace imports, to 400. Idle speed rotary valve dirty, causing the engine idle speed unstable, easy to stall. Dirty fuel pressure regulator, so that ECU fuel and not the pressure difference between inlet chamber, resulting in high fuel injection pressure, fuel mixture too much lead to partial concentration, which appears to accelerate bad, idle high and unstable. On engine idling valve, vacuum tube, throttle and crankshaft exhaust pipe cleaning, is Beverly TU5JP / K and TU3JP / K common EFI engine maintenance, you can do it yourself. And do it DIY work, some common engine failure will not occur, but also can enrich the level of car, you may wish to try. 1, idle valve cleaning Valve in the rear engine idling, it is an air filter through a pipe connected at one end and then into the air in the engine room, is a two-coil control valves, there are four different conduction flux position. When it turns on, the engine idle speed directly from the air filter through the intake valves are to maintain the engine idle. As the long-term use, it is inevitable that produces fouling, resulting in idle valve is not smooth, stable idling, or traffic in the flame. Recommend cleaning once per quarter, you can DIY. As follows: 1, the engine in the flame, cools, opened the hood, good support. Prepare a carburetor cleaner, plastic sign, good quality paper towels. 2, idle valve in the engine rear wheel should be standing on the right side, first unplug the idle valve plug on the drive line, pay attention to the direction of the plug in order to resume correctly. Do not use brute force, first wire clamp Qiaodiao, gently pull on the line. 3, with a hexagonal wrench loosen the two hex screws, remove the idle valve and clean with carburetor cleaner, and with a clean towel to remove the fouling inside the plastic sign can remove the finger does not get to the place of the fouling . Paper Tiger or if the source of compressed air can blow on idle valve. After cleaning, shake the idle valve, cylinder valve is feeling its movement freely. If there is delay card phenomenon, indicating that no clean, cleaning agents should be injected to the body, then shake, repeated several times until the clean up. 4, according to open the reverse order, kept clean, the idle valve is installed correctly plugged in the drive line idle valve plug. Try to start the engine. Second, wash vacuum Intake from the engine room has a diameter of about 10mm rubber tube, through a three links connecting the fuel pressure regulator and inlet air sensor, intake air pressure sensor in the engine department store right front. RPC new free man, RLC, etc. using TU3JP / K engine valves before entering the pressure sensor, through a small white translucent plastic pots, I think it is to prevent the pollution of oil vapor pressure sensor and the set, do not skip it pressure sensors connected directly. The TU5JP / K engine valves directly connected to pressure sensors, plastic pots do not deposit oil, therefore, TU5JP / K engine oil pressure sensor is more easily contaminated steam. DIY cleaning is easy, is: 1, the vacuum tube is pulled down, with a 80cm length of thin wire, hook a size suitable clean cloth, pulled from the vacuum tubes had to wipe off the oil. Be careful not to hurt the rubber tube, can not let the cloth fibers left in the pipeline, you can use compressed air blow on. 2, wash with carburetor cleaner pressure sensor, a small plastic sign with a tissue and carefully wipe clean. Small white translucent plastic pots can also be removed and cleaned with a paper towel to ensure the smooth management of two speak out. 3, look at the fuel regulator and vacuum-tube junction is contaminated, please use the paper towel and carefully wipe clean small plastic sign. 4, according to the original way to connect, clean, all tubes inserted in place, can not leak. 5, start engine, idle running to see the stability. If unstable, the pressure sensor tube is generally not plugged, or leaking, or unreasonable. No need to fear, flame, serious examination again, you can re-plugged. Third, clean throttle As the long-term use, throttle will fouling, impact throttle opening and closing, causing the engine not working properly. Proposal, in a clean air filter, check whether the throttle barrel fouling, if fouling, you can use carburetor cleaner wash. Is (assuming that air filter has been open): 1, using a slotted screwdriver, loosen the air filter and throttle body of the metal clamp fastening screw, so that air filter cap and throttle body separation. 2, keep the throttle is off, the carburetor cleaner to spray around the door, re-use paper towel and carefully wipe clean small plastic sign. 3, breaking his hand back and forth moving the throttle plate fan * for to see whether the throttle cleaned, if able to open closed with ease. Then air filter and throttle body connected to receive bit which makes the seal, tighten the metal clamp screws. 4 Note: automatic transmission cars do not unplug the throttle position sensor connector, throttle body on it, otherwise, need to use the equipment, re-initialization of the accelerator pedal position; careful not to spray carburetor cleaner to the section Valve body of air filter rubber seal ring, it will corrode the rubber ring, sealing effect. The cleaning is part of the throttle body cleaning, to complete cleaning, pull the throttle to be removed, the throttle body into the chamber from the engine to completely remove, clean with carburetor cleaner. Too much trouble, it is recommended to do the maintenance station. Especially the autopilot, throttle body removed, the use of special instruments to initialize the accelerator pedal position, he could not do. 4, cleaning crankcase exhaust tube and filter method Monthly cleaning crankcase exhaust pipe and filter, to reduce emissions of the oil throttle and pressure sensor tube, gas pressure regulator vacuum tube contamination. The regular maintenance, DIY is easy, make recommendations to their practice. * For the specific method: 1, turn off heat after the car until the engine cools, opened the hood, good support. 2, to prepare good quality paper towels, and a "carburetor cleaner." 3, standing at the cabin on the left side of the left front wheel, left hand exhaust rubber pipe, air filter should be close. Right fist against his left hand back. Exhaust rubber pipe and air filter should be torn off. Seizing the left exhaust pipe rubber washed, otherwise, waste lubricating oil will flow out, dripping cabin. 4 out exhaust filter, rinse with carburetor cleaner and placed on clean paper towels. 5, exhaust pipe end with a tissue to the plastic joint oil clean, as the air filter connector of the oil cleaned. 6, the exhaust filter into the exhaust pipe end of the plastic joints, the, harder to exhaust pipe and air filter a good fit.
