Abstract Recently, a new design of engine combustion that achieves higher efficiency and less NOx emission has been proposed. Some researchers have started studying the concept, which is called Homogeneous Charge Compression Ignition (HCCI), but there have been few reports on investigations using a future prospective alternative fuel, natural gas. In this study, natural gas fueled operation of HCCI using a single cylinder gas engine was conducted. Operating and exhaust characteristics were obtained. Experimental data confirmed the potential of higher efficiency and less NOx emission, though THC and CO were higher. Based on these data, the feasibility of this concept for gas engines is also examined.

The performance of engine fueled with diesel/biodiesel blends was tested. It was indicated from the experimental results that the brake power, torque out and brake specific fuel consumption of engine fueled with diesel/biodiesel caused slight variations, while NOx emission increased significantly compared with engine fueled with diesel. In order to reduce NOx emission of engine fueled with pure biodiesel, retarding fuel delivery advance angle was used, and the NOx emission tests revealed that the NOx emission decreased significantly at different engine speeds.
