IMPORTANCE AND ROLE OF ADDITIVES FOR ESTIMATING PERFORMANCE AND EMISSIONS IN C.I ENGINES USING ALCOHOL AS FUELS- A STUDY.
Innovative thinking led to find various techniques by which alcohol can be used as fuel in diesel engine, amongst the fuels alternative proposed, the most favourest ones are methanol and ethanol . so far no established method is available to run a normal diesel engine with a compression ratio from 14:1 to 20:1 by using alcohol as fuel.This is because, the properties of diesel engine fuels differs from the properties of diesel fuels . The specific tendency of alcohols to ignite easily from a hot surface makes it suitable to ignite in a diesel engine by different methods .The advantage of this property of alcohols enables to design and construct a new type of engine called surface ignition engine. In this work it is tried to bring out the advantages of additives to alcohol fuel on the performance of CI Engines. The Additives such as n-butanol,hexanol, 1-octylamino-3octyloxy-2propanol&N-octyl nitramine had been mixed with the blends of diesel & ethy alcohol and experiments are carried out.the present research work is proposed to carry out the experimental investigation on a ceramic hot surface ignition engine by adding Ethylnitrate,Butylnitrate,Diisipropylether and Dimethylether as additives to ethanol/methanol as a fuel with an objective to find the best one interms of performance ,emission and combustion parameters.
