Abstract :
A common rail and injector is controlled by engine ECU (electrical control unit) with many input sensors in HSDI (high speed direct injection) diesel engine. The engine ECU plays the most important role in controlling the diesel engine. It is important to analyze the operations of engine ECU with a variation of data of input sensors. A simulator is necessary in order to observe easily both the operating conditions and fault situations of engine ECU. In this paper, the characteristics of input sensors and their interface circuits in the engine ECU are analyzed, and the system for generating waveforms of all input sensors is implemented by both the 16-bit DSP TMS320LF2407 and host computer. The simulator of engine ECU is applied to a real vehicle in order to investigate the operations of ECU with a variation of input sensors data.
