What about Shenbao d50 engine jitter?

1. Oil path problem: The postal path problem is generally that the oil path is blocked, resulting in poor oil supply, which is characterized by engine jitter, unstable waiting speed and flameout during driving; In addition, the engine will shake when the oil pump fails. Determine the problem of the oil pump, disconnect the oil pipe and check the related process. 2. Circuit problem: Check whether the correct ignition is accurate. General abnormal ignition is a normal ignition problem; Check whether the spark plug is aging, whether the gap is the same and whether the gap changes; In addition, the abnormal operation of the distributor will also cause engine jitter; 3. Mechanical reasons: check the running state of the engine, whether there is any abnormal sound and the sound of the valve; Check whether the working condition of the belt is loose. SicBod50: 1。 Causes of engine jitter. The most common reason for car jitter is that the throttle is too dirty or the nozzle has too much carbon. When there is too much carbon deposit in the engine, the gasoline sprayed by the cold start injector will be absorbed by the carbon deposit. 2. The mixture caused by cold start is too thin, making it difficult to start. In this case, only when the gasoline absorbed by carbon deposits is saturated can it easily enter the car. After getting on the bus, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will make the mixture thicker and the combustible mixture of the engine thinner and thinner, resulting in idling jitter after cold start. 3. The lower the temperature, the more oil is needed for cold start, and the existence of carbon deposit will affect the success of cold start. There are many reasons for the abnormal vibration of the engine of this car. If it is really simple, engine vibration, oil quality, cleanliness of oil circuit, injector, intake valve and throttle valve, matching and service life of spark plug and even ignition coil and cylinder pipeline, and even cylinder head have been damaged. These conditions may cause vibration. The best way is to clean the throttle, injector and air intake regularly.
