Effect of valve timing events on the performance of compressed natural gas direct injection (CNGDI) engine using simulation

The research for Compressed Natural Gas Direct Injection (CNGDI) vehicle has been explored recently. Through DI system there is an area that needs improvement on the performance outcome. The objective of this study is to investigate the influence of valve timing events on Compressed Natural Gas Dire...
