What is the cause of engine jitter when Jiangling is idling completely?

1, the throttle is too dirty. After the car started, the engine was idling. At this time, air needs to continuously reach the cylinder through the throttle to burn gasoline. If the throttle valve is too dirty, it will reduce the intake volume of the intake manifold, which will not reach the normal air-fuel ratio and will cause engine jitter.

2. There is too much carbon in the engine. Too long service life of the engine will cause too much carbon deposition inside, which will lead to engine jitter.

Engine technical characteristics

1, the engine valve drive mechanism adopts the structure of hydraulic support ball rocker arm.

Compared with the hydraulic tappet valve drive mechanism widely used in general gasoline engines, this new valve drive mechanism has the advantage of relatively small friction torque, so it requires less driving force, which can effectively reduce the power consumption and fuel consumption of the engine.

2. In order to effectively reduce the weight of the whole vehicle, the 1.4 liter gasoline engine adopts aluminum alloy cylinder block, which achieves a very obvious lightweight effect.

3. Replacing the traditional metal intake pipe with the plastic intake pipe made of special materials and technology can not only achieve the effect of lightweight, but also effectively reduce the wall resistance of the intake pipe, improve the intake efficiency and increase the engine power.
