Abstract: As everyone is aware, the price of fuel keeps on fluctuating from time to time, therefore, oil conservation and saving on fuel is everybody’s concern. We all know that extensive use of petroleum products has left our environment highly polluted, leading to various health hazards, ozone layer depletion and global warming. Therefore, it has become inevitable to have some solution at our disposal so as to conserve fuel, reduce pollution and save our environment. One way to conserve fuel, reduce pollution and save our environment is the use of fuel catalyst. Fuel catalyst is a mixture of compounds which helps in efficient burning of fuel. We have carried out a test on SI engine with plain petrol and mixture of plain petrol and fuel catalyst. Work also reports evaluation of thermal performance of plain petrol with 0.38% and 0.79% by mass of fuel catalyst and compared with that of plain petrol. Also fuel properties relevant to the fuel were determined for the various concentrations of fuel catalyst, in a mixture of plain petrol and fuel catalyst and also for plain petrol. In this paper it is shown that higher concentration of fuel catalyst in plain petrol leads to effective combustion of supplied fuel which results in lower air fuel ratio for same speed. There is improvement in the thermal performance of engine due to blending of fuel catalyst with plain petrol. Also effect of fuel catalyst on the environment is noted by the measurement of exhaust emission of plain petrol and mixture of plain petrol & fuel catalyst.

Keywords: Plain petrol, Fuel catalyst, Thermal performance, Brake thermal efficiency.
