Diesel Engine Electronic Control Technology

Bulky, noisy, smoky, so many people are poor impression Diesel intuitive, and more complex structure Diesel, and many people lack an understanding of the diesel engine, particularly on modern art diesel lack of understanding. In fact, after many years of research and application of new technologies, the situation has been in modern diesel engine with the same metaphor of the past. Modern diesel vehicles generally use EFI, common rail, turbocharged technology in the cold, the weight, noise, smoke and other major breakthrough has been made to the gasoline engine level. At present foreign Diesel light-duty vehicles has become increasingly popular, Mercedes-Benz, Volkswagen, BMW, Renault, Volvo, and other European brand cars have diesel engine models.

EFI in the area of diesel and petrol are the main differences between gasoline machine EFI system is air-fuel ratio control (the ratio of air and gasoline), diesel EFI system by controlling the fuel injection is time to adjust the size of the output, and the diesel engine fuel injection engine control by the speed and accelerator pedal position (drawbars throttle position) to decide. Thus, the basic principle is the basis of computer speed sensor and throttle position sensor input signals, first calculate the basic fuel injection quantity, and then under water temperature, inlet temperature of the air pressure sensor signal amendment, and again from the control sets Position sensor signal feedback amendment, to determine the optimum amount of fuel injection.
