The best compression ratio of modified piston for compressed natural gas(CNG)usage

The best compression ratio of modified piston for compressed natural gas(CNG)usage

Compression ratio can be defined as the pressure different between top dead center(TDC)and bottom dead center(BDC)of the piston in the combustion chamber.Compression ratio takes importance element to determine the power of the engine. Therefore,the objective of this study to determine the best compr...
