| Abstract: | The reasons of the power performances reduction for gasoline/natural gas engine have been analyzed when natural gas is used. Every measurement and their technical states for improving the power performances of the engine have been summarized. It is a workable and economic measure that a mixer is designed optimally and the intake system is matched carefully with engine and the ignition-advanced angle is increased slightly. The measure of boosting and cooling induction gas can increase the performances and worth being studied further. |
