文摘
- •
Hydrogen/gasoline combined injection method with hydrogen direct injection was proposed.
- •
Cold start performance of combined injection is better than that of pure gasoline.
- •
First effective firing cycle can be realized easily with combined fuel injection.
- •
Combined injection has large adaptive range of ignition timing for engine cold start.
- •
HC and CO emissions during cold start are obviously reduced for combined injection.
