Experimental Study of Emissions and Performance of Internal Combustion Engine Fuels

Experimental study of 8 different internal combustion fuels is conducted. The 8 fuels are: octane 90, octane 95, blend of 10% methanol & 90% octane 90, blend of 10% methanol & 90% octane 95, blend of 20% methanol & 80% octane 90, blend of 20% methanol & 80% octane 95, blend of 30% methanol & 70% octane 90 and blend of 30% methanol & 70% octane 95. A dynamometer setup is used to conduct the experiments and the emissions and torque at different speeds were measured. The efficiency, power and specific fuel consumption were calculated. The experimental results are represented graphically from which the advantages and disadvantages of each fuel relevant to environment and performance are extracted. The best fuels for internal combustion engines are recommended.
