The electronic fuel injection control system takes the electronic control device as the control center, uses various sensors installed in different parts of the engine to measure various working parameters of the engine. According to the control program set in the computer, the fuel injection quantity is accurately controlled by controlling the fuel injector, so that the engine can obtain the best concentration of mixture under various working conditions.

In most diesel and gasoline injection systems, coated (diamond-like carbon) coated parts are available. In order to meet the standards of environmental vehicles, the injection pressure is increasing. This only applies to coated mechanical parts.
