Combustion Behaviors of a Compression-Ignition Engine Fueled with Biodiesel at Different Fuel Delivery Advance Angles

Abstract:

The performance of engine fueled with biodiesel was tested. It was indicated from the experimental results that NOx emission of biodiesel reduced significantly with decreasing fuel delivery advance angle BTDC, while soot emission also reduced when the fuel delivery timing was retarded for 2°CA, and the starting position of heat release rate retarded with the delay of fuel delivery timing. It can be concluded that, retarding fuel delivery timing was an effective method to reduce the NOx emission of engine fueled with biodiesel, but led to reduce the brake power output slightly.
