　　大众途观着车怠速高的原因，大众途观起步怠速时有异响「一定记住」

　　据和记百科网站「明月踏清风」消息，近日，大众途观着车怠速高的原因，大众途观起步怠速时有异响「一定记住」引发热议，大众途观起步怠速时有异响同样引起许多争议，对此众网友各抒己见。但到底是怎么回事呢？和记百科为您解答。

大众途观着车怠速高的原因

　　发动机积碳过多，节气门过脏或喷油嘴积碳过多。当发动机内部的积碳过多时，冷启动喷油头喷出的汽油会被积碳大量吸收，导致冷启动的混合气过稀，使得启动困难，这种状况下，只有等到积碳吸收的汽油饱和，才容易着车，着车后吸附在积碳上的汽油又会被发动机的真空吸力吸入汽缸内燃烧，又使混合气变浓，发动机的可燃混合气时稀时浓，造成冷启动后怠速抖动。

大众途观起步怠速时有异响

　　1、变速器油缺少或油质变坏。

　　2、变速器轴承磨损、松旷或轴承损坏。

　　3、变速器轴弯曲。

　　4、齿轮啮合不正常，啮合间隙过大或过小。

　　【英文介绍/For English】：

　　Excessive carbon deposition in the engine, dirty throttle valve or excessive carbon deposition in the fuel injector. When there is too much carbon deposition inside the engine, the gasoline ejected from the fuel injection head at the cold start will be absorbed by the carbon deposition, resulting in the mixture of cold start being too lean, making it difficult to start. When it is saturated, it is easy to start the car. After the car is loaded, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the vacuum suction of the engine and burned, which will make the mixture richer. Idle jitter.
