What are the possible causes of auto-start jitter?
1, serious carbon deposition inside the engine.
Often manifested as throttle carbon deposition, nozzle carbon deposition, spark plug carbon deposition, piston carbon deposition. When these carbon deposits accumulate to a certain extent, they will absorb the heat of combustion and even cause deflagration and detonation. If the nozzle is blocked, it will lead to poor atomization effect, which will not only consume oil, but also pollute the environment.
2, the ignition system problem
Generally, spark plugs have too much carbon deposition and insufficient ignition voltage, which leads to flameout, even single cylinder or multi-cylinder flameout. The engine will shake due to lack of power, and it will be between flameout and fire when the shaking is serious.
3. The fuel pressure is unstable
The fuel system includes fuel tank, gasoline filter, gasoline pump, oil-gas separator, oil pipe and fuel meter. If one of them has problems, blockage or oil leakage, it will lead to unstable oil pressure and intermittent engine power jitter. It is possible that the oil pressure will not shake when oil is supplied, but the present situation of no oil supply has not changed.
4, engine internal parts aging
Usually this will only happen after the vehicle has been used for a certain number of years or mileage. Engine power will shake when it drops seriously. Usually, this kind of car is easy to shake at low speed, and the symptoms are improved to some extent after refueling, but it consumes a lot of fuel.
