Study on intelligent equipment for testing electronic control injection system of engine

On the basis of analyzing the special structures of the electronic control system of direct injection gasoline engine, a micro computer controlled equipment is designed. The equipment can measure the sensors' signals, and output signals according to the sensors' characteristic which can be input directly to the ECU. Tests and application showed that the equipment had good precision and could be easily applied to test the performance of the direct gasoline injection engine.
