Head jitter of starter of Opel Astra gtc cold car

Low ignition energy leads to jitter 1, and low ignition energy: the first problem of automobile cold start is that the temperature is low, the temperature in the engine is not enough, and the temperature of fuel and lubricating oil is not enough, so more fuel should be injected to meet the power requirements during cold start. The larger the gap between spark plugs, the smaller the ignition energy. Fuel atomization is not good at low temperature, and fuel needs high ignition energy. When the automobile is used for a long time, the ignition gap of the spark plug is easy to become larger, which leads to the decrease of ignition energy, thus affecting the power performance and making the automobile shake. 2. Valve and air intake caused by carbon deposit jitter If carbon deposit occurs in the valve and air intake of the engine, because carbon deposit can absorb a proper amount of fuel (just like water flows through the river bank and soil absorbs water), ECU makes a wrong judgment. The computer actually controls the injection of 100 parts of oil and gas, but only 90 parts actually enter the cylinder (10 parts are absorbed by carbon deposits), so even if the remaining 90 parts of mixed oil and gas are fully burned, the required power cannot be achieved, and the jitter phenomenon is inevitable.
