%X This paper reports the computer simulation based theoretical and the test rig based experimental investigations for improving the performance and emission characteristics of a two stroke cycle spark ignition engine. Computer simulation was carried out using a standard software. Models were prepared for the carburettor and gasoline direct injection modes. Using the design and operating data of a standard commercial two stroke cycle spark ignition engine results were generated in the carburettor and gasoline direct injection modes. Different parameters like brake power, BSFC, CO and HC emissions, exhaust and spark plug temperatures, peak cylinder gas pressure and its cyclic variations were studied in the carburettor and GDI modes. There was improvement in engine power and reduction in BSFC in the GDI mode as compared to carburettor mode. The CO and HC emissions were reduced in the GDI mode due to better atomization and reduced scavenging loses.
