The paper deals
with the impact assessment of the additives used in diesel and petrol
fuel to improve the power and emission parameters of the vehicle and its consumption. The usage
of additives in engine fuels have an increasing tendency. The manufacturers claim that ad
ditives
have positive impact on engine operating parameters, cleaning the fuel supply system and
decreasing fuel consumption by improving the engine combustion process. Based on the above
statements, measurements were performed to determine change in the e
ngine parameters utilising
additives. Measurements were performed under laboratory conditions on the MAHA MSR 500
test bench (dynamometer) to simulate free driving cycle selected by authors, which were carried
out at constant engine speeds and constant loa
d. Focus have been given on tracking of the
vehicle's external speed characteristic and measurement of selected parameters: CO, HC, O

, fuel
consumption (petrol engine) and smoke, fuel consumption (diesel engine). Resulting values of
the driving cycles mea
sured before and after additives application have been then compared. The
result of experiment confirmed that tested fuel additives improved performance and torque
depending on engine mileage and fuel type. Tested diesel engine with the higher mileage (app

) improvement has not been measured. Emissions were improved in both
engines. Difference has been also measured in fuel economy as in pe

increased while in the diesel engine it decreased. This paper brings new complex
view on energetical and emission changes in internal combustion engines.
