The invention of IC engines revolutionized the living habits of people to a great extent in particular petrol engines, which offer mode of individual transport. Indeed the petrol engine powered automobile and diesel engine powered buses and trucks are the symbols of our modern technological society. Four stroke engines offer many advantages like higher thermal efficiency, volumetric efficiency than two stroke engines. In the scenario of depletion of fossil fuels, the search for alternative fuels has become inevitable. Alcohols, the renewable fuels are important substitutes of gasoline, as their properties are comparable to gasoline fuels. However, for alcohol engines, aldehyde levels should be checked. These aldehydes are responsible for pungent smell of the engine and affect the human beings when inhaled in the large quantities. The volatile aldehydes are eye and respiratory tract irritants. Though Government legislation has not been pronounced regarding the control of aldehyde emissions, when more and more alcohol engines are coming to existence, severe measures the controlling of aldehydes emitted out through the exhaust of the alcohol run engines will have to be taken as serious view. Aldehyde levels were controlled by selective catalytic reduction technique. CCE showed reduction of aldehyde levels in comparison with CE with test fuels.

Keywords: Alternative fuels, CE, CCE, Selective Catalytic Reduction Technique
