Up-to-date Electronic Injection Systems of Locomotive-Type Diesel Engines
The task of improving fuel combustion efficiency and ecological indexes of locomotive-type diesel engines is now rather actual. While addressing this task mechanical fuel handling system conversion to electronic control is necessary. Application of electronic injection control system makes possible flexible lead angle and injection pressure regulation in accord with diesel engine operating condition, thus leading to better fuel combustion efficiency and ecological indexes due to significant quality improvement of diesel engine cycle. Two types of electronically controlled fuel handling system are used with locomotive-type diesel engines. The paper represents structure and functional principle of each of them. It also contains analysis of technical characteristics of home-made and foreign diesel engines, fitted with electronic fuel injection systems. There was performed analysis of the systems’ advantages and drawbacks having in mind their specific design features and operation with locomotive-type diesel engines. Resulting from this analysis there was identified the most suitable for the day type of electronic injection control system of locomotive-type diesel engine.
