          汽車發動機怠速抖動是什么原因引起的?

          來源:http://www.webloomafrica.com/ 日期:2023-02-04 發布人:admin
          如果發動機怠速達到正常的工作溫度后,仍然抖動,那就屬于故障了,怠速如果車身抖動明顯,濟南奧迪汽車維修廠家認為可能意味著車輛存在下面4種狀況:
          If the engine still shakes after the idle speed reaches the normal operating temperature, it is a fault. If the body shakes obviously at idle speed, the Jinan Audi auto repair manufacturer believes that it may mean that the vehicle has the following four conditions:
          1、發動機積碳嚴重
          1. The engine has serious carbon deposition
          車輛長時間行駛后,發動機或多或少會產生積碳,積碳主要附著于進排氣門、發動機缸體、噴油嘴、節氣門等位置,如果積碳過多,會顯著影響發動機缸內燃油噴射量、空氣進入量,進而影響發動機缸內燃油空氣混合比,使發動機出現怠速抖動現象。
          After the vehicle has been driving for a long time, the engine will produce more or less carbon deposits, which are mainly attached to the intake and exhaust valves, engine block, fuel injection nozzle, throttle valve and other positions. If the carbon deposits are too much, it will significantly affect the amount of fuel injection and air intake in the engine cylinder, and then affect the fuel-air mixture ratio in the engine cylinder, causing the engine to shake at idle speed.
          2、發動機部件老化
          2. Aging of engine components
          發動機懸置(機腳墊)位于車身和發動機之間,是汽車發動機避震系統的一部分,負責吸收發動機在運轉時候的細微抖動。如果懸置出現問題,其自身的濾震效果便會降低,造成怠速時車身發生抖動。這種抖動通常發生在發動機負荷發生變化的時候,比如踩下剎車掛D檔、開空調、開大燈等。
          The engine mount (foot pad) is located between the vehicle body and the engine. It is a part of the shock absorption system of the vehicle engine and is responsible for absorbing the slight vibration of the engine during operation. If there is a problem with the suspension, its vibration filtering effect will be reduced, causing the body to shake at idle speed. This jitter usually occurs when the engine load changes, such as pressing the brake to shift to D gear, turning on the air conditioner, and turning on the headlights.

          3、點火系統問題
          3. Ignition system problem
          點火系統中某個缸不點火,或者點火弱也會導致怠速抖動,怠速不穩的問題。這里火花塞點火線圈都要檢查,火花塞是否存在電機燒蝕損壞,間隙過大等問題,點火線圈是否有漏電,電壓低,損壞類問題。另外還要注意點火時間是否正確,點火時間不對會出現爆震、發動機無力等問題,一樣會導致發動機運行不穩,抖動。
          If a cylinder in the ignition system does not ignite, or the ignition is weak, it will also cause idle jitter and unstable idle speed. Here, the spark plug ignition coil should be checked to see whether the spark plug has problems such as motor ablation damage, excessive gap, and whether the ignition coil has leakage, low voltage, and damage. In addition, pay attention to whether the ignition time is correct. If the ignition time is not correct, knock, engine weakness and other problems will occur, which will also lead to unstable engine operation and jitter.
          4、油壓不穩
          4. Unstable oil pressure
          造成發動機油壓不穩的因素很多,例如機油缺少、機油臟污、機油變稀、機油油管漏油、機油泵損壞或其零部件磨損超標等等。值得一提的是,如果發動機持續在機油壓力過低的條件下運轉,情況嚴重時可能會造成發動機“燒瓦”,此時發動機將不能啟動,需進行刮瓦或換瓦。
          There are many factors that cause the instability of engine oil pressure, such as lack of oil, oil dirt, oil thinning, oil pipe leakage, oil pump damage or excessive wear of its parts, etc. It is worth mentioning that if the engine continues to operate under the condition of low oil pressure, it may cause the engine to "burn out" when the situation is serious. At this time, the engine will not be able to start, and it needs to be scraped or replaced.
          怠速抖動具體怎么解決?
          How to solve idle jitter?
          1.原地怠速車身抖動,這個需要更換發動機機腳膠。
          1. The vehicle body shakes at idle speed in place, which requires replacing the engine foot glue.
          2.低速高檔急加速時車身抖動,檢查火花塞。
          2. Check the spark plug when the body shakes at low speed and high speed during rapid acceleration.
          3.開空調時剎車抖動,更換電子風扇。
          3. The brake shakes when the air conditioner is turned on. Replace the electronic fan.
          4.高速踩剎車方向盤抖動,更換前輪剎車盤。
          4. Press the brake at high speed and the steering wheel shakes. Replace the front wheel brake disc.
          5.高速踩剎車制動踏板抖動,更換后輪剎車盤。
          5. Press the brake pedal at high speed to shake, and replace the rear wheel brake disc.
          6.跑高速時方向盤抖動,兩前輪需要做動平衡。更多相關汽車維修的事項就來我們網站http://www.webloomafrica.com咨詢吧!
          6. The steering wheel shakes when running at high speed, and the two front wheels need to be dynamically balanced. For more matters related to vehicle maintenance, please visit our website http://www.webloomafrica.com Ask!
