Fuel injection system refers to the fuel supply device that uses the injector to inject a certain amount of fuel into the cylinder or intake port under a certain pressure. According to the different types of fuel injection, it can be divided into gasoline injection system, diesel injection system, gas fuel injection system and so on. According to the different control methods, it can be divided into mechanical control, electronic control and electromechanical hybrid control.

HCVAC coating machine is used for coating and heat treatment of spray parts, which can reduce fuel consumption, improve wear resistance and achieve compact design. Achieve innovative powertrain concepts to save fuel and lubricants and reduce pollutant emissions; improve wear resistance and service life of components, thereby extending maintenance intervals and reducing the need for spare parts; allowing more compact design and using lighter materials to reduce the overall weight. In order to meet the standards of environmental vehicles, the injection pressure is increasing. This only applies to coated mechanical parts.
