TheSI engine could not be operatedefficientlywith neat ethanol fuel due to its high selfignition temperature and latent heat of vaporizationcompared with petrol.The above issues of SI engine is turned to be an objective of this study, where the SI engine was operated with neat ethanol fuel under different inlet air temperatures.The result of this study is indicated that the neat ethanol fuel could be utilized efficiently in SI engine with waste heat recovery system.The specific fuel consumption (SFC) of SI engine has decreased with neat ethanol fuel compared with petrol fuelled engine. It is also found that theSI engine has registered almost same brake thermal efficiency (BTE) values with neat ethanol compared to petrol.The exhaust emissions such as carbon monoxide (CO) and Hydrocarbon (HC)were reduced in SI engine, at the same time there was an increase in oxide of nitrogen (NOx).

Feed stock cost and NOX emission are the major barriers for commercialization of biodiesel. Waste cooking oil is well identified as one of the cheapest feed stocks for biodiesel production. This chapter reduces NOX emission of waste cooking oil biodiesel. Test fuel blends are prepared by mixing diesel (20 to 50 v/v%), butanol (5 v/v%), and waste cooking oil biodiesel (45 to 75 v/v%). Fuel properties of waste cooking oil biodiesel are enhanced due to addition of diesel and butanol. Brake specific energy consumption of the blends is higher than diesel fuel. Harmful emissions like carbon monoxide, nitrous oxide, and smoke opacity are lower for blends than diesel fuel. Increasing biodiesel concentration in blend also reduces hydrocarbon emission to a significant extent. The obtained results justify the suitability of proposed cheap blends for diesel engine emission reduction.
