The addition of additive into fuels for internal combustion engines is a common practice. They were added for various purposes such as to help clean engine deposits and to enhance engine combustion process. The expected benefits of using additives were to reduce the emission of unwanted components and to enhance the power output from the engine. This research is intended in particular to elucidate the effect of additives when blended with petrol on exhaust emission. The effect of various concentrations of STP and Waxco Tech additives at different engine speed on exhaust emission were studied. Presence of CO, RCs, NO, CO2 and excess ~ were monitored. The concentrations by volume of additive in petrol studied were 0"/0, 05%, 1.0%, 1.5% and 2.0%. Presence of additive was generally found to reduce Res emission, signuying improvement in combustion of the fuel, while increasing the emission of NO. Emission of NO was lowest when the concentrations of additives were between 0.5 - 1.0%. This is inline with the recommended concentration of 05% for the use of the additives. STP additive was fuund to be better than Waxco Tech additive. It was also observed that the emission of NO increases at higher engine speed. The effect of additive is similar to that of increasing engine speed suggesting that the combustion of petrol in the presence of additives result in higher combustion temperatures. This study establishes the positive effect of blending additives with petroL It also establishes that the recommended concentration should be observed because if higher concentrations are used the emission of NO will increase substantially.
