Experimental Investigation for Combustion Stability of Semi Direct Electronic Injection in Four Stroke SI Engine 2011-01-0229

This Paper presents the results of experimental work conducted on a four-stroke spark ignited engine to reduce the emissions and to enhance the performance using semi direct electronic fuel injection. A comparative study was carried out with the base engine for finding out the effect of semi direct injection.
The injector is mounted on the inlet manifold in such a way that the fuel is injected on the back of the inlet valve. The in-cylinder pressures were recorded for 1000 continuous cycles using a piezo-electric pressure pickup and PC based data acquisition system.
The results show that the stratified mixture formation achieved by semi-direct injection results in improved engine performance and reduced emission & cycle-to-cycle variations.
