Development of Control Model for Diesel Ignited NG Engine Based on Simulink |
| |
| Abstract: | In order to improve the thermal efficiency of diesel ignited natural gas engine at medium and low load,an electronic control system equipped with electronic throttle valve was introduced.The engine control model with electronic throttle valve control function for the system was developed with Simulink software.Then embedded code was generated with code generation tool and was downloaded to the controller for test use.The results show that the control algorithm of throttle valve is effective. The engine control algorithm can control the air-fuel ratio of mixture effectively at medium and low load so that the engine ther-mal efficiency improves obviously. |
