What happened when the elf cold car turned off a few seconds after it started?

Cold start jitter is mostly caused by poor fuel combustion. There is too much colloidal water in the fuel tank and too much carbon in the engine. The cold start is not taken to the combustion chamber, then mixed in the fuel tank and pumped into the combustion chamber. Jitter caused by poor combustion. During cold start, the gasoline sprayed by the fuel injection head will be absorbed by a large amount of carbon deposits, which will lead to too thin mixture during cold start and make the start shake. If there is carbon deposit in the valve and intake of the engine, ECU will make a wrong judgment, because carbon deposit can absorb a proper amount of fuel. If the computer actually controls the ejection of 100 oil and gas, but only 90 oil and gas actually enter the cylinder (10 oil and gas are absorbed by carbon deposits), even if the remaining 90 oil and gas mixtures in the fuel reserve of the brigade are completely burned, the power required for blasting will not be achieved, and the phenomenon of jitter is inevitable. Engine jitter has the following reasons: Duan Meng 1, serious carbon deposition in the engine, serious car caused by jitter, and the most common thing is that the injector is dirty or has too much carbon deposition; 2, ignition system problems, check the working conditions of spark plugs, high-voltage lines and ignition coils; 3. The oil pressure is unstable. If the supply pressure of the pump is abnormal or the intake pressure sensor is wrong or not working well, the body will shake; 4, engine parts aging; Excessive carbon deposits in engine emissions are absorbed by cold start spray [hallo.amcgo.cn/article/840719.html]
