The performance and emissions of a spark-ignited, port-injected, gasoline-fuelled, water-cooled, small-size modern motorcycle engine were investigated. For this purpose, an experimental test-rig was built up utilizing a small motorcycle engine for carrying out the practical tests. Experimental tests were performed for a range of engine speeds, various air-fuel ratios with a WOT condition and fi...

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

Often called 'the heart of the engine', the fuel injection system is without any doubt one of the most important systems. It meters the fuel delivery according to engine requirements, it generates the high injection pressure required for fuel atomization, for air-fuel mixing and for combustion and it contributes to the fuel distribution in the combustion system-hence it significantly affects en...

Dual-fuel (DF) operation with methanol-diesel allows to reduce CO2 emissions, increase efficiency and decrease NOx soot. This paper describes the experimental results methanol-water (MeOH-W) blends as a fuel, has three objectives: (1) whether water acts knock suppressant, enabling higher diesel substitution ratios, (2) if can be measure control engine-out emissions given its cooling effect, (3)...

The use of alternative fuels can improve the performance diesel engine in terms pollution, [1], [2], [3].Low-carbon [2] successfully replace conventional modern engines or future [1]. This may be an efficient method to ameliorate exhaust emissions for 2050, especially CO 2 reduction, important issue at internal combustion automotive fleets. liquid petroleum gas, [1-5] which has a low carbon con...
