The blockage of the fuel filter or too much impurities in the fuel tank will cause poor oil flow in the oil line and aggravate the engine shaking. ( 5) Fault of the exhaust system. Failures such as aging of the exhaust pipe and damage to the silencer will lead to poor exhaust effect and engine shaking. Two. Impact (1) Increase the economic burden. Engine shaking will lead to waste of fuel and increase the economic burden of the vehicle. ( 2) The acceleration performance declines.Engine jitter will affect the acceleration performance of the vehicle, which will increase the traffic conditions when the vehicle passes through the intersection, and there may be risks from a safety perspective. ( 3) The engine comfort is reduced. Adhering to the needs of modern people for driving comfort, engine shaking will increase the psychological burden of drivers and reduce driving comfort. 3.
