EN Combustion of lean hydrogen-air mixtures in an internal combustion (IC) spark ignited (SI) engine in respect of combustion knock effect is presented in this paper. It is known that making the combustible mixture leaner leads to both decreasing in-cylinder peak temperature of combustion and lengtheni[...]

EN It is known that Exhaust Gas Recirculation (EGR) can be successfully applied not only for reducing NOx content in exhaust gases but also for reduction of combustion knock in SI engines. From this point of view, EGR can be particularly effective for knock elimination in the hydrogen reciprocating eng[...]

EN Combustion knock in a hydrogen fuelled engine has many different characteristic as compared to knock occurring in the gasoline engine. This is a result of differences in the gasoline and hydrogen combustion mechanisms which lead to knock. Hydrogen as the engine fuel is able to produce combustion kno[...]

EN In the US transportation sector uses two-thirds of the country's total oil consumption. In order to minimize the consumption in this sector there is a need to investigate alternate sources of energy. Biodiesel is a possible alternative to conventional diesel. Biodiesel has many characteristics simil[...]

EN Biofuels have the potential to diversify transportation energy sources and reduce dependence on petroleum based fuels. Of these biofuels, Methyl-ester biodiesel holds significant potential as it has many characteristics similar to petroleum based diesel and can be blended with petroleum. However, bi[...]

EN Flammability limits and flame speeds of dilute-lean fuel mixtures of hydrogen (H2) and acetylem premixed with oxygen (02) and nitrogen (N2) were examined with a detailed kinetics model. These mixtures are used in a preburn in a constant volume combustion vessel to create elevated temperatures and pr[...]
