Analysis of Exhaust Emissions from Two Stroke Spark Ignition Engine with Copper Coated Piston Operating with Methyl Alcohol Blended Gasoline
Abstract: Experiments were conducted to evaluate and control the exhaust emissions from two stroke single cylinder, spark ignition (SI) engine, with alcohol blended gasoline (80 % gasoline, 20 % methanol, by volume) having copper coated engine [CCE, copper- (thickness, 300) coated on piston crown] and compared with conventional SI engine (CE) with pure gasoline operation. The exhaust emissions of carbon monoxide (CO) and unburnt hydrocarbons (UBHC) were determined at different values of Brake Mean Effective Pressure (BMEP) with Netel Chromatograph CO/UBHC analyzer. Aldehyde levels were determined by Dinitrophenyl Hydrazine (DNPH) method. Copper coated combustion chamber with alcohol blended gasoline considerably reduced the pollutants in comparison with CE with pure gasoline operation.
