The reduction in fossil fuel reserves, in parallel with the world's increasing energy demand, is also a serious problem. Improving these mentioned problems for electric vehicles requires time ( EEA, 2016b). To mitigate the problem, the use of diesel vehicles in urban centres have been restricted at various locations around the world ( EPCA, 2017 TfL, 2016).Ĭurrently, research and development have been accelerated on electric-motor-powered vehicles, but there are still issues such as insufficient battery storage capacity, limited availability of charging stations and excessive charging times in this scenario. This situation causes environmental concerns, especially due to nitrous oxides and particulate matter ( EEA, 2016a). In recent years, not only has the number of diesel vehicles increased, but also the rate of growth has increased in the vehicle park ( EEA, 2017).

A slight reduction in nitrous oxides and carbon monoxide emissions was observed when using methane at full load. Thanks to the high knock resistance of methane, the most suitable ignition advance value was decided for the methane-fuelled simulation by considering the maximum thermal efficiency to limit assumed reductions in indicated thermal efficiency and indicated mean effective pressure compared to previous studies. The theoretical model used a combustion model and a chemical kinetics model to compare the effects of methane and petrol on engine performance and emissions at different engine speeds. The theoretical results for methane and petrol were finally compared for different engine speeds. A theoretical engine model was then verified using experimental data. In this research study, performance and in-cylinder pressure data were collected from petrol- and methane-fuelled SI engines. Using alternative fuels is important for SI engines. This could lead to greater use of low-powered spark-ignition (SI) engines in hybrid electrical cars. Diesel engines using compression ignition are increasingly prohibited in cities due to increased environmental concerns.
