Effects of Injection Strategies on Mixture Formation and Combustion in a Spark-Ignition Engine Fueled with Syngas-Biogas-Hydrogen

The paper presents the effects of blend injection and dual strategies on mixture formation combustion syngas-biogas-hydrogen fueling engine working in solar-biomass hybrid renewable energy system. research was performed by simulation method a retrofitted Honda GX200 spark-ignition engine. results show that at end compression process, case 50% syngas-50% biogas, fuel-rich zone positioned top chamber, whereas injection, this found piston. In hydrogen supplied, area observed piston with slightly deflected towards inlet port both cases injection. When shifting from mode to mode, biogas engine, mean temperature exhaust gas decreased 1208 K 1161 NOx concentration 1919 ppm 1288 ppm. decreases 1283 1187 leading decrease 3268 2231 has advantage lower emission, higher efficiency
