Diesel Engine Electronic Control Technology and the development of the electrical control system similar to gasoline. Since the 1980s, has begun to enter the market Hyundai diesel engine with electronic control system is the growing number of project control, control tasks from simple to complex, until all control. For example, the early electronic-controlled fuel injection system used a "position control," maintaining a traditional pulsed high voltage supply principle, but through a computer control unit at the core of the position servo control and change the fuel adjustment Rack ( inline pump), or fuel adjustment sleeve (VE-distribution pump), the location of the fuel pump to adjust for the cycle (jet) fuel. However, as institutions position servo slow implementation of the frequency response, low frequency control, control precision instability, after nearly a decade of development, 1980s and early 1990s, "Time control" electronically controlled fuel-injection system developed using the powerful new high-speed Electromagnetic valve instead of the traditional oil-conditioning rack (inline pump), or fuel adjustment sleeve (VE-distribution pump), high-pressure fuel directly to a digital high-frequency adjustment, from the closure of the solenoid valve closure time and duration for the decision cycle (spray) and for oil (spray) when the oil is. Nevertheless, this "time control" electronically controlled fuel-injection system remains the traditional principle of pulsed high voltage supply. Until the mid-1990s, a new type of electronically controlled common rail fuel injection system was made to abandon the traditional pulsed high voltage supply principle, the "time - pressure control" of the fuel metering principle, the public through hydraulic oil in the track Continuous control and the process of the cylinder fuel injection control solenoid valve to achieve a combination of the cycle for the (jet) fuel control, and the only diesel engine electronic control of fuel injection technology has entered a new stage of development.
