A review on emission analysis of waste vegetable oil methyl ester on IC engine

Biodiesel is to be a solution for future. Biodiesel is produced by transesterificaton the oil or fat with an alcohol (methanol/ethanol) in the presence of a base catalyst. Waste vegetable oil methyl ester is also a major feedstock in the production of biodiesel. Mainly animal fats and vegetable oils are used for the production of biodiesel. The transesterification reaction yields methyl or ethyl esters (biodiesel) and a byproduct of glycerin. Parametric optimization of process parameters viz. reaction time, reaction temperature, methanol/oil molar ratio yields in ecologically friendly properties, having the potential opportunity to be used in biodiesel production process as heterogeneous base catalyst. Optimization adopted by using various optimization techniques such as Taguchi, SRM, genetic algorithms etc. Today with the help of advance technology and the knowledge there is a way to control pollution; use of biofuel can be an alternative to current fuels. Biodiesel may be used in any diesel automotive engine in its pure form or blended with petroleum-based diesel. No further modifications are required, and the results are low cost, renewable source, less exhaust emissions. This work shows how use of biodiesel will affect the emission of pollutants and performance parameters of diesel engine. Diesel Engine is compression ignition engine and use diesel as fuel. Biodiesel can be used in pure form or may be blended with petroleum diesel at any concentration.
