Application of Real-time Monitoring of Cylinder Pressure in Multi-point Electronic Fuel Injection Gas Engines
This paper introduces the application of real-time monitoring system for cylinder pressure in multi-point electronic fuel injection gas engines.The combustion information(maximum burst pressure,average effec-tive pressure,etc.)of each cylinder collected by the system is used for online real-time closed-loop correction of parameters such as ignition timing and injection duration for each cylinder to optimize the combustion perform-ance and improve the working uniformity of each cylinder.And compare the data with real-time adjustment of in-jection duration and ignition timing according to exhaust temperature and detonation.The results indicate that the application of the real-time monitoring system for cylinder pressure has a better effect on improving the per-formance and optimizing the uniformity of each cylinder.
