Application of Compressed Natural Gas (CNG) in diesel engines has always been important, especially in the field of automotive engineering. This is due to easy accessibility, better mixing quality and good combustion characteristics of the CNG fuel. In this study the application of CNG fuel along with diesel oil in a heavy duty direct-injection automotive diesel engine is experimentally investi...

according to the global fuel crisis, it seems necessary to use alternative fuel instead of gasoline. since the natural gas is cheaper, have higher frequency than gasoline and less pollution, it is a suitable fuel. many efforts have been done in order to replace gasoline with natural gas. one of the methods is to inject natural gas and gasoline fuel simultaneously and to use the benefits of both...

Objectives • Develop realistic and internally consistent detailed designs for automotive gasoline fuel processor/ proton exchange membrane (PEM) fuel cell systems and direct hydrogen PEM fuel cell systems by using current-year technology. • Apply Design for Manufacture and Assembly (DFMA) design and costing techniques to compare system designs at low, medium, and high annual production rates. •...

Looking forward in 1995, automobile manufacturers identified a potential shift in customer preferences to lighter weight, fuel-efficient automobiles; fuel-cell powered cars; and hybrid gas/electric vehicles. To make existing cars more fuel efficient and to meet the coming needs of alternatively powered vehicles, automobile original equipment manufacturers (OEMs) needed lighter components. These...
