Experimental Investigations On Two Stroke Cycle Spark Ignition Gasoline Direct Injection Engine 2005-26-009

This paper describes the experimental investigations on a single cylinder, two stroke spark ignition engine in the carburettor and in-cylinder injection (GDI) modes. The experiments were conducted on the engine in the carburettor mode up to 80% throttle opening and for different combinations of speed and load. The engine was modified and fitted with an in-cylinder injector in the head. Fuel was supplied through injector with the help of a high pressure DC pump. Experiments for varying speed and load were conducted under in-cylinder injection mode up to 80% throttle opening. It was observed that there is a significant reduction in BSFC, unburnt HC and CO emissions. Also, the power output of the engine has shown an improvement.
