Long - hole and geometrical proportion type of mixing unit is finally adapted in lpg supply system, and power and torque output of lpg engine are improved by increasing compression ratio, and ignition characteristic is tried to adjusted to satisfy engine performance. meantime emission performance and noise level of lpg engine at full - throttle and other various part - throttle operations are tested and compared with former gasoline engine. ( 3 ) it is verified by engine dyno tests that lpg engine has better synthesized performance at aspects of power and torque, fuel economy, as well as emission than former gasoline engine
