Analysis and comparison of performance and emissions of compression ignition engine fuelled with diesel and different bio-fuels blended with Methanol

The present fossil fuel crisis and increasing vehicle population made us to think of alternate fuels. The abundance of the fossil fuels is expected to be exhaust in another 30-40 years. The cost of the fossil fuels is day by day increasing and also the emission from these fuels increases the air pollution. With keeping in view of all the above said points, it is made us to think of alternate fuels for all CI Engines. Among alternate fuels, the Mango Seed oil blended with Ethanolwill promise for substituting the diesel. With vegetable oils there is combustion problems and which leads to more emissions in the exhaust.To overcome the above problems we use combustion boosters at the time of combustion. So here we use Mango Seed oil blended with Ethanolas alternative fuels in semi adiabatic diesel Engine and perform various tests and evaluate its performance. The present investigation evaluates Methanol blended with Palma oil, Mahua oil, Coconut oil in CI Engine. A Twin cylinder C I engine adapted to study the brake thermal efficiency, brake specific energy consumption, and emissions. In this study, the diesel engine was tested using Diesel and Methanol blended with Palma oil, Mahua oil,Coconut oil Palma oil, Mahua oil,Coconut oil. From this study the emissions like HC,CO₂,CO,NOx,Aldehydes,Smokehas been reduced and Methanol blended with vegetable oils are substitute to diesel fuel.
