초록

This study was performed to find out performance characteristics and develop LNG engine. this system was designed and manufactured by modification of a diesel using the LNgas. The engine was manufactured to be able to change the compression ratio by changing thickness of the gasket. The results are summarized brake power and torque of the engine increased when compression ratio of the engine increased. The engine output showed more power with gasoline by 5-10% then LNG under compression ratio of 9.5.and maximum brake thermal effeiency was noted when air-fuel ratio was 15.5. The concentrations of NOx, CO and HC in the exhaust gas showed lower values with the engine fueled LNG then gasoline.
