如果發(fā)動(dòng)機(jī)怠速達(dá)到正常的工作溫度后，仍然抖動(dòng)，那就屬于故障了，怠速如果車身抖動(dòng)明顯，
濟(jì)南奧迪汽車維修廠家認(rèn)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(fā)動(dòng)機(jī)積碳嚴(yán)重
1. The engine has serious carbon deposition
車輛長(zhǎng)時(shí)間行駛后，發(fā)動(dòng)機(jī)或多或少會(huì)產(chǎn)生積碳，積碳主要附著于進(jìn)排氣門、發(fā)動(dòng)機(jī)缸體、噴油嘴、節(jié)氣門等位置，如果積碳過多，會(huì)顯著影響發(fā)動(dòng)機(jī)缸內(nèi)燃油噴射量、空氣進(jìn)入量，進(jìn)而影響發(fā)動(dòng)機(jī)缸內(nèi)燃油空氣混合比，使發(fā)動(dòng)機(jī)出現(xiàn)怠速抖動(dòng)現(xiàn)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(fā)動(dòng)機(jī)部件老化
2. Aging of engine components
發(fā)動(dòng)機(jī)懸置(機(jī)腳墊)位于車身和發(fā)動(dòng)機(jī)之間，是汽車發(fā)動(dòng)機(jī)避震系統(tǒng)的一部分，負(fù)責(zé)吸收發(fā)動(dòng)機(jī)在運(yùn)轉(zhuǎn)時(shí)候的細(xì)微抖動(dòng)。如果懸置出現(xiàn)問題，其自身的濾震效果便會(huì)降低，造成怠速時(shí)車身發(fā)生抖動(dòng)。這種抖動(dòng)通常發(fā)生在發(fā)動(dòng)機(jī)負(fù)荷發(fā)生變化的時(shí)候，比如踩下剎車掛D檔、開空調(diào)、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(diǎn)火系統(tǒng)問題
3. Ignition system problem
點(diǎn)火系統(tǒng)中某個(gè)缸不點(diǎn)火，或者點(diǎn)火弱也會(huì)導(dǎo)致怠速抖動(dòng)，怠速不穩(wěn)的問題。這里火花塞點(diǎn)火線圈都要檢查，火花塞是否存在電機(jī)燒蝕損壞，間隙過大等問題，點(diǎn)火線圈是否有漏電，電壓低，損壞類問題。另外還要注意點(diǎn)火時(shí)間是否正確，點(diǎn)火時(shí)間不對(duì)會(huì)出現(xiàn)爆震、發(fā)動(dòng)機(jī)無力等問題，一樣會(huì)導(dǎo)致發(fā)動(dòng)機(jī)運(yùn)行不穩(wěn)，抖動(dòng)。
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(wěn)
4. Unstable oil pressure
造成發(fā)動(dòng)機(jī)油壓不穩(wěn)的因素很多，例如機(jī)油缺少、機(jī)油臟污、機(jī)油變稀、機(jī)油油管漏油、機(jī)油泵損壞或其零部件磨損超標(biāo)等等。值得一提的是，如果發(fā)動(dòng)機(jī)持續(xù)在機(jī)油壓力過低的條件下運(yùn)轉(zhuǎn)，情況嚴(yán)重時(shí)可能會(huì)造成發(fā)動(dòng)機(jī)“燒瓦”，此時(shí)發(fā)動(dòng)機(jī)將不能啟動(dòng)，需進(jìn)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(dòng)具體怎么解決？
How to solve idle jitter?
1.原地怠速車身抖動(dòng)，這個(gè)需要更換發(fā)動(dòng)機(jī)機(jī)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(shí)車身抖動(dòng)，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(diào)時(shí)剎車抖動(dòng)，更換電子風(fēng)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(dòng)，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(dòng)踏板抖動(dòng)，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. 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://m.shguiyong.com Ask!
