The Performance Analysis of LPG as the Vehicle Fuel

As the global shortage of oil resources and the rapid increase in car ownership, using gas as the alternative fuel is getting more and more important. Gas fuel, such as CNG (compressed natural gas)/LNG (liquefied natural gas) and LPG (liquefied petroleum gas), with resource-rich, less pollution and other features, are desirable alternative fuels for cars. Through engine bench test, a comparative analysis of power performance between LPG-single fuel engine and gasoline engine was done. The result shows that, by applying LPG injection on single-fuel engine, the power of the LPG engine increases to a higher level than gasoline engines. And combined with the analysis based on the study of domestic development of NGV, predictions could be made that new fuel vehicles will be well utilized in future.
