Survey of the Electronic Injection and Control of Diesel Engines

The electronic injection and control of gasoline engines has caused a revolution of the conventional four-stroke and two-stroke SI engines. Now, this technique is also playing a more and more important role in the Diesel engine area.

In this paper, we will focus on the electronic injection and control of Diesel engines to discuss injection systems, dynamic models and advanced controls. First, the typical R&D results on first generation and second generation of the electronic Diesel injection systems will be reported. Different design approaches will be described. Then, dynamic submodels of the Diesel fuel injection systems and dynamic models for the whole Diesel engine will be summarized. The main dynamic processes and modelling philosophy will be analyzed. Finally, the advanced Diesel governing techniques and Diesel management systems will be reviewed.

At the end of the paper, some suggestions for further development and a theoretical summarization on the electronic injection and control of Diesel engines will be presented.
