Exhaust emissions created by spark ignition engines result in air pollution, human health risks, and ecological imbalance. The provision of the catalytic converter as a catalyst and then as a result of the air injection system of 60 l/m into the catalytic converter is carried out and evaluated for maximum emission reduction, is secondly. From the results, it was discovered that up to a 5% improvement in brake specific fuel efficiency, an increase of 21% in carbon monoxide, 29 percent in unburnt hydrocarbon, and 29 percent in NOx emissions were all reduced. The catalytic converter alone reduced CO and UHC by 40%, and by the use of air injection it was 60%. At a 7% EGR rate combined with the catalytic converter and air injection device, the CO& UHC emissions dropped by 54% and 52% respectively at 54% and 52% respectively at 7%.
