Alternative fuels provide huge rural employment, and reduce the dependency on fossil fuels, which are renewable, eco-friendly and help to preserve the atmosphere. The gaseous forms of alternative fuels are LPG, CNG, H2, biogas and producer gas. The solid fuels are not used in IC engines due to their handling and storage difficulties. This paper aims to reduce the exhaust emissions from spark ignited engines by in-cylinder treatment. Two organic fuel additives, namely substituted formamide (Addt.-I) and substituted ketone with six carbon atoms (Addt.-II) were used in this work. The various percentages of concentration of additives i.e. 0.5%, 1.0%, 1.5%, 2.0% by volume were used in both additives. The experimental work was carried out in a 197CC, single cylinder, four stroke petrol engine of GENSET-HONDA. Carbon monoxide (CO), hydrocarbon (HC) and oxides of nitrogen (NOx) in the exhaust gas have been measured using “KANE” make exhaust gas analyzer. The experimental results show that an appreciable amount of reduction in CO and HC were obtained for all the concentrations of additive-I and additive-II. But in case of NOx emission, additive-I shown an adverse effect and incase of additive-II, during higher loads for additive concentrations of 1.0% & 2.0% by volume, the NOx level was marginally increased compared to neat gasoline.
