摘  要:
随着经济的不断发展,汽车数量不断增加,汽车尾气对环境污染越来越严重。为此,从进气量、混合气的热值、点火提前角度等方面分析了影响天然气汽车动力性能的因素,并指出天然气燃料汽车动力性能下降的主要原因是发动机进气量的减少及混合气热值的偏低。分析得出:采用天然气加浓混合气对提高天然气发动机的功率是有限的,要大幅度提高天然气发动机的功率,在大负荷时减气加油是比较理想的方案。

摘  要:
With the development of the economy and the automobile's quantity increases continually automobile's tail gas potties the environment more and more serious. Hence, in the paper, the influence factor of natural gas fuel automobile is analyzed. For example, the quantity of inlet air, the heat energy value of mixed gas (natural gas and air), ignition timing and so on. The result show that the main reason result in engine power decreases is inlet air reduce and the heat energy value of mixed gas on the low side. The engine lower can be improved by complementarities gasoline in the case of higher load is a perfect scheme for improving the engine power in large extent.
