A four-stroke single cylinder Compression Ignition(C I) Engine is converted into a ceramic hot surface ignition ethanol engine to reduce the emission. Ethanol is blended with diesel along with some agro waste coconut oil. In this, the performance and emission characteristics of the modified engine is analysed and compared to the base engine. The glow plug is coated with a Partially Stabilized Zirconium (PSZ), Piston crown is coated with Aluminium Oxide (Al2O3) and 50% of the clearance volume is reduced by grinding the top of the engine block. Due to high auto ignition temperature of ethanol, a pre heater is introduced. This experiment is effective not only in reducing smoke density and fuel consumption but also increase in engine output. Ethanol is renewable and oxygenated bio-based fuel; therefore it has enough potential to reduce emissions when used in compression Ignition Engine. It leads to reduction in the emission of CO2 and other toxic gases which are harmful to the environment. Many researches completed for using ethanol as an alternative fuel but it is not completely achieved in India. This is due to problems in refilling stations, problems in engine while using ethanol and lower rate of ethanol production. Hence this experiment is conducted to troubleshoot the problems while using ethanol as an alternative fuel in CI engines.
