Cheng Jing's cold car began to shake violently and flameout, and the exhaust pipe spewed a lot of water. Was it washed by the cylinder gasket?

Will there be a lot of white smoke from the exhaust pipe? There will be a lot of white smoke, that is, the cylinder pad is washed, otherwise it is not a cylinder pad; It is normal for the exhaust pipe to spray water in a cold car with low temperature. In fact, the chemical composition of our gasoline or diesel oil itself is hydrocarbon (CH) composed of carbon and hydrogen. If it burns completely and cleanly, the products are carbon dioxide (CO2) and water (H2O), and the exhaust pipe will produce water, indicating that the fuel in the engine cylinder is completely burned; It is normal for a cold car to shake and ignite again. Is it usually caused by dirty throttle or carbon deposition in cylinder or valve?
