The objective of the work was investigation of possibility of dual fuelling of CI engine with diesel fuel and ethyl alcohol in order to decrease engine emission and increase its thermal efficiency. Alcohol, which is injected to the engine inlet port evaporates quickly, but doesn't ignite (due to low cetane number). After self-ignition of diesel fuel, ignited alcohol would promote further burnin...

Abstract The poppet valve is by far the most widely used in cylinder head design of internal combustion (IC) engines; however, valves themselves create significant flow restrictions during both intake and exhaust strokes, thus causing a reduction volumetric efficiency that affects overall engine performance. By removing restrictive from path air into out allowing to unobstructed, any given IC c...

Internal combustion (IC) engines serve as a viable small-scale and portable option for electricity generation. While there are several aspects of IC engines that limit their efficiency, one of the major detractors is the unrestrained combustion reaction that is the initial step in the conversion of the chemical bond energy of the fuel into useful work. Another viable small-scale electricity gen...

IC engines are considered as major contributors to the deterioration of the environment, therefore there is an increasing demand to go for alternative fuels for both SI and CI engine so as to maintain the ecological balance as well as reduce dependency on petroleum and socio economic aspects. The gaseous fuel such as LPG has been widely used throughout the world in SI engines as it impacts gree...
