There is nothing wrong with BYD s6 engine, and it often shuts down automatically. What happened?

It may be caused by excessive carbon deposition in throttle, idle motor, air intake and combustion chamber. Due to too much carbon and dirt in the air inlet, the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake air volume, resulting in the mixture being too rich or too thin and the engine unable to start. It is also possible that the electronic control system has poor fuel constant pressure performance and low fuel pressure, which leads to poor fuel injection atomization and difficult start-up. First, check the carbon deposition of the throttle body when the hot car is running. Secondly, the resistance of the crankshaft position sensor itself is abnormal, which leads to the disappearance of the crankshaft speed signal after the hot car, leading to the engine flameout. The gasoline pump itself fails, and the resistance changes after long-term work, which can not provide normal fuel pressure, leading to engine flameout; Ignition system failure, ignition module overheating can not work normally, ignition voltage is invalid, engine flameout; Abnormal throttle signal voltage and abnormal engine computer control will cause the vehicle to stall when driving; There is a virtual connection in the line, which causes the engine to stall occasionally. This kind of fault needs a comprehensive inspection. I hope my answer is helpful to you.
