IMPACT OF USING DIFFERENT TYPES OF GASOLINE ON SELECTED VEHICLE PROPERTIES

The article focuses on determining the impact of using different types of gasoline on selected vehicle properties. To perform the measurements, there were six types of gasoline chosen from different gas stations and they differed in price, octane rating, and in an amount of additives and biocomponents. The immediate effect of petrol on engine performance and torque, exhaust gas composition and fuel purchase costs was examined. The results have shown a relatively low impact of gasoline on a vehicle's dynamic properties. The most visible change was measured when comparing the most expensive fuel to the cheapest one. There was an increase in the engine torque from 156 Nm to 160 Nm measured. Such a difference is lower than the deviation of measuring. The differences measured in the composition of the exhaust gases are low. However, there is a significant impact in choice of gasoline on the costs of fuel purchase.
