Abstract

In order to provide a real-time simulation environment for diesel engine PHM algorithm verification, the hardware-in-the-loop real-time simulation of high-power supercharged diesel engine failure was conducted based on mean value and equivalent model principle, and the feasibility was verified by setting the air filter clogging fault and the intercooler efficiency degradation fault. The research results show that the average error of fault real-time simulation model is less than 5% with a realtime simulation period of 10 ms, which can meet the needs of real-time simulation verification of PHM algorithm for diesel engine.
