What is the Decisive Factor in Fuel Injection Quantity?
1 Answers
The decisive factor in fuel injection quantity is the water temperature sensor. Composition of the water temperature sensor: The water temperature and water level sensor consists of a temperature control part and a water level control part. It is also equipped with a pressure reducing device before the electric valve and a rotary muffler heater for heating. Function of the water temperature sensor: The function of the water temperature sensor is to convert the cooling water temperature into an electrical signal, which is input to the ECU to: adjust the fuel injection quantity; increase the fuel injection quantity at low temperatures. Adjust the ignition timing; increase the ignition timing at low temperatures, and delay it at high temperatures to prevent knocking. Affect the idle control valve; at low temperatures, the ECU controls the idle control valve based on the water temperature sensor signal to increase the idle speed, affecting the EGR valve.
