This study investigates the effect of vehicle mileage, vehicle characteristics and the fuels on exhaust gas performance. In order to research this topic, 1260 vehicles with spark ignition engines and 960 vehicles with compression ignition engines were sampled and surveyed. The exhaust emissions are measured with a CO-hydrocarbon (HC) emission gas analyser and a filter-type smoke analyser. The results show that the amount of emission gas is not directly related to the mileage covered by the vehicle. However, the engine specifications, such as valve train type or air induction type, influence emissions. In addition, the liquid petroleum gas (LPG) vehicles emit more CO and HC than gasoline vehicles, although it is widely known that an LPG engine emits less exhaust. Smaller cars emit a lot of CO and HC compared with a larger car, and 1300 and 1800 cm3 displacement volume vehicles also produce higher exhaust emissions. These results indicate that new legal restrictions are required and more research on reducing emissions is needed.
