What are the disadvantages of the traditional diesel fuel supply system?

altitude and ambient temperature have great influence on the oil supply system.

In fact, the advantages of the fuel supply system of electronically controlled diesel engine reflect the disadvantages of the mechanical fuel injection system. The traditional fuel supply system of diesel engine adopts mechanical oil pump. Because this fuel supply system is mechanical, the fuel supply advance angle is a fixed angle, and the fuel supply is controlled according to the mechanical accelerator pedal, so the response is slow, and the fuel supply and fuel supply timing are not necessarily the best values. In addition, because it can provide the best fuel supply and fuel supply timing, the torque is increased. Because the fuel supply system is a traditional mechanical fuel injection, the external environment has a great influence on it, especially the low-speed torque. The electronic control system can be corrected according to the altitude and the external environment temperature, so the power is relatively improved. The electronic control fuel supply system can improve the fuel economy.
