燃气汽车功率下降原因分析及防止措施

Problems in Use and Countermeasures of Natural Gas Vehicles

分析了气体燃料发动机功率下降的原因并提出了相应的措施。采用气体加浓、汽油加浓 ,以及提高发动机充气系数 ,适当提高发动机压缩比 ,可以提高气体燃料发动机的功率。

The causes involved in power decrease of natural gas vehicles are described in this paper. The measures can increase the power of natural gas vehicles, ie. gas becoming heavier, gasoline becoming heavier, increasing the air charge coefficent of engine and increasing accordingly the engine compression ratio.
