Experimental Study on the Performance of a Natural Gas Engine

Abstract:

Power performance tests of natural gas engine were carried out using a self-dependent developed electronic injection system and ignition system, and a comparative analysis between the natural gas engine and original gasoline engine was conducted. The result shows that if the gasoline engine is fueled with NG torque of the engine decreases and with the throttle opening increases, the decrease amplitude increases. Developing a suitable electronic ignition system can recover engine torque to some extent. Under the conditions that both throttle opening and rotation speed of the engine are constant, MBT angle increases with the decrease of mixture concentration.
