广汽传祺gs4怠速发动机异响故障原因有哪些

　　1、异响仅在怠速或低速运转时存在。发响的原因有：活塞与气缸壁间隙过大；活塞销装配过紧或连杆轴承装配过紧；挺杆与其导孔间隙过大；配气凸轮轮廓磨损；有时，起动抓松动而使皮带轮发响（在转速改变时明显）。

　　2、维持在某转速时声响紊乱，急减速时相继发出短暂声响。发响的原因有：凸轮轴正时齿轮破裂或其固定螺母松动；曲轴折断；活塞销衬套松旷；凸轮轴轴向间隙过大或其衬套松旷。

　　3、异响在发动机急加速时出现，维持高速运转时声响仍存在。发响的原因有：连杆轴承松旷、轴瓦烧熔或尺寸不符而转动；曲轴轴承松旷或轴瓦烧容；活塞销折断；曲轴折断。

　　【英文介绍/For English】：

　　1. Abnormal noise only exists when idling or running at low speed. The reasons for the noise are: the clearance between the piston and the cylinder wall is too large; the assembly of the piston pin or the connecting rod bearing is too tight; the clearance between the tappet and its guide hole is too large; the profile of the valve cam is worn; Beeping (noticeable at RPM changes).

　　2. The sound is disordered when maintained at a certain speed, and a short sound is successively issued when the speed is decelerated rapidly. The reasons for the sound are: the camshaft timing gear is broken or its fixing nut is loose; the crankshaft is broken; the piston pin bushing is loose; the camshaft axial clearance is too large or its bushing is loose.

　　3. The abnormal sound occurs when the engine is rapidly accelerated, and the sound still exists when the high-speed operation is maintained. The reasons for the noise are: the connecting rod bearing is loose, the bearing bush is burned or the size does not match and rotate; the crankshaft bearing is loose or the bearing bush is burned; the piston pin is broken; the crankshaft is broken.
