Abstract

Fuel efficiency and emission characteristics are two main concerns that must be addressed. Fuelling system is one of the crucial variables that must be focused on. Fuel injection system has a long term potential as a medium to supply suppressed fuel because of its high fuel delivery efficiency, low emission characteristics and fuel economy. Fuel injector angle plays an important role in achieving quality combustion. In this study the influences of the injector angle to engine performances and emission characteristics were investigated. Experimental works comprised one throttle opening position with various dynamometer loads for two angles: 48° and 68°. From this study, the result shows that 68° was the optimum angle, which produced high brake power, high brake mean effective pressure, low brake specific fuel consumption and low hydrocarbon emission.
