What is the jitter of BYD Tang fuel engine?

If the car body slightly wobbles or deviates during driving, it is generally caused by tires. First of all, it may be that the wheel balance is not good, and the owner needs to make a four-wheel positioning and dynamic balance as soon as possible. If the vehicle is not running off, please carry out tire dynamic balance. Reasons for jitter of BYD fuel engine: 1. 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. Engine jitter and vibration refers to the phenomenon that the engine is short of cylinders or one or more cylinders are not working normally, which leads to unstable rotation, jitter and vibration of the engine. There are many specific reasons, which can be judged according to the actual test and debugging of various models.
