奥迪车子专修发动机怠速问题

文章作者:济南京奥奥迪3S店 发布时间:2022-04-12 10
我们的汽车车主有时会遇到发动机空转的情况,这其实是发动机怠速了,很多人会忽略这个情况,以为这并不是什么大问题。但是如果这个问题一直不解决的话,很有可能造成发动机的磨损。下面我们汽车车子专修公司就带大家分析一下发动机怠速问题的原因:
Our car owners sometimes encounter engine idling. In fact, the engine is idling. Many people ignore this situation and think it's not a big problem. However, if this problem is not solved, it is likely to cause engine wear. Next, our auto repair company will take you to analyze the causes of engine idle speed:
(1)进气歧管或各种阀泄漏
(1) Leakage of intake manifold or various valves
当不该进入的空气、汽油蒸汽、燃烧废气进入到进气歧管,造成混合气过浓或过稀,使发动机燃烧不正常。当漏气位置只影响个别汽缸时,发动机会出现较剧烈的抖动,对冷车怠速影响更大。
When the air, gasoline vapor and combustion exhaust gas that should not enter enter enter the intake manifold, the mixture is too rich or too thin, resulting in abnormal combustion of the engine. When the air leakage position only affects individual cylinders, the engine will vibrate violently, which has a greater impact on cold idle speed.
常见原因有:进气总管卡子松动或胶管破裂;进气歧管衬垫漏气;进气歧管破损或其它机件将进气歧管磨出孔洞。
The common causes are: the clamp of the intake manifold is loose or the rubber hose is broken; Air leakage of intake manifold gasket; The intake manifold is damaged or other parts grind holes in the intake manifold.
(2)节气门和进气道积垢过多
(2) Excessive fouling on throttle and intake ports
节气门和周围进气道的积炭、污垢过多,空气通道截面积发生变化,使得控制单元无法准确控制怠速进气量,造成混合气过浓或过稀,使燃烧不正常。
There is too much carbon and dirt on the throttle and the surrounding air inlet, and the cross-sectional area of the air channel changes, which makes the control unit unable to accurately control the idle air intake, resulting in too rich or lean mixture and abnormal combustion.
常见原因有:节气门有油污或积炭;节气门周围的进气道有油污、积炭;怠速步进电机、占空比电磁阀、旋转电磁阀有油污、积炭。
Common causes are: oil stain or carbon deposit on the throttle valve; There is oil stain and carbon deposit in the air inlet around the throttle; The idle stepping motor, duty cycle solenoid valve and rotary solenoid valve have oil stain and carbon deposit.
(3)怠速空气执行元件故障
(3) Idle air actuator failure
怠速空气执行元件故障导致怠速空气控制不准确。
Idle air actuator failure leads to inaccurate idle air control.
常见原因有:节气门电机损坏或发卡;怠速步进电机、占空比电磁阀、旋转电磁阀损坏或发卡。
The common causes are: the throttle motor is damaged or jammed; The idle stepper motor, duty cycle solenoid valve and rotary solenoid valve are damaged or jammed.
(4)进气量失准
(4) Air intake misalignment
控制单元接收错误信号而发出错误的指令,引起发动机怠速进气量控制失准,使发动机燃烧不正常,属于怠速不稳的间接原因。
The control unit receives the wrong signal and sends out the wrong command, which causes the inaccurate control of engine idle air intake and abnormal engine combustion, which belongs to the indirect cause of unstable idle speed.
常见原因有:空气流量计或其线路故障;进气压力传感器或其线路故障;发动机控制单元插头因进水接触不良或电脑内部故障。
Common causes are: air flow meter or its circuit failure; Intake pressure sensor or its circuit fault; The plug of the engine control unit has poor contact due to water ingress or internal failure of the computer.
