In terms of speed regulation mode, EFI machine and electric regulator belong to electronic speed regulation Fantao, which is different from mechanical speed regulation control mode. But there is an essential difference between the injection control mode and the speed control execution mode. The electric regulator is a traditional high-pressure pump that directly injects diesel into the cylinder. Its injection pressure is limited by the pressure valve on the injector, and the oil pressure is not as high as that of the electronic injection; After the fuel pressure in the high-pressure oil pipe reaches the set value of the pressure valve, it will directly open the valve and inject it into the cylinder. The pressure of the pressure valve cannot be very high due to the influence of mechanical manufacturing; In terms of fuel economy, the EFI has sufficient fuel combustion, so it is the most fuel-efficient. EFI is an advanced technology in recent years, which overcomes the main defects of traditional diesel engines. The core of common rail electronically controlled fuel injection technology is a fuel supply mode that completely separates the generation of injection pressure from the injection process in a closed environment composed of high-pressure oil pump, pressure sensor and computer control unit (ECU). Simply put, the high-pressure fuel pump sends the high-pressure fuel into the fuel rail. There is always a constant pressure value in the fuel rail. The computer control unit ECU will determine the proper injection pressure and injection time according to the load speed and other signals, so as to control the opening of the fuel injector. The accelerator for mechanical speed regulation is fixed, so the general fuel consumption is relatively high. There is no module installed. It monitors the voltage, current and frequency, but there is no power display and some protection functions.
