• We model SI engine with methane–hydrogen fuel.
• We examine the effect of induction system on engine performance and emissions.
• The engine performance is affected by equivalence ratio, induction system, H2/CH4 percentage.
• Hydrogen addition in fuel corresponding with BSFC decreasing for both injection systems.
• The addition of some hydrogen to methane produces notable improvements to engine performance and emissions.
Mixtures of hydrogen and methane are considered viable alternative fuels to gasoline due to lower overall pollutant emissions.The basic intent of the present work is to evaluate the effect of using blend hydrogen–methane fuel with varying fuel induction systems for spark ignition engines on its overall performance and emission. Firstly a model of blends hydrogen–methane ICE has been designed and validated by experimental data. The model is used as an engine simulator. Equivalence ratio, fuel injection system, hydrogen–methane ratio, and engine speed are selected as the effective and controllable parameters on engine emissions and performance characteristics. Secondly, the effects of variation parameters on emissions and performance characteristics of the modeled engine are illustrated. Finally, the reasons of the engine behavior and characteristics under variations of these parameters are fully discussed. The analysis of the results shows that the addition of some hydrogen to methane between 0.4 and 0.6 H2 with equivalence ratio near to stoichiometric and engine speed between 2000 and 3000 rpm produces notable improvements to engine performance and emissions.
