The Technical Modification and Performance Analysis of Diesel/LNG Dual Fuel Engines

Abstract:

As the global shortage of oil resource and the rapid increase in car ownership, using gas as the alternative fuel is getting more and more important. Gas fuel, such as LNG (liquefied natural gas), with resource-rich, less pollution and other features, is desirable alternative fuels for cars. In this article, through the engine bench test, a comparative analysis of power performance, fuel economy, emission between diesel/LNG dual engine and diesel engine was done. The result shows that, compared to the original machine , power performance of modified diesel / LNG dual fuel engine decline but isnt obvious. At the same time , fuel economy has a substantial increase. The use of natural gas can relieve shortage of global oil resource and the supply-demand imbalance of oil products. The emission of modified diesel / LNG dual fuel engine has a better state than that of original machines. This kind of modified dual fuel engine is simple, low cost, easily promoted and will be well utilized in future.
