Abstract

The aim of this paper was to evaluate the influence of the fuel additive „VIF Super diesel additive winter mixture“ on the observed parameters of a vehicle with a diesel engine. The effect of the additive was investigated on Citroën C4 with a 1.6 HDi engine with a mileage of over 159,000 km. The testing of the effect of the additive took place in laboratory conditions on a cylindrical stool. The test vehicle’s exhaust gas treatment system included an exhaust gas recirculation, an oxidation catalyst, and a particulate filter. The power, energy (fuel consumption), and emission (NOx, k-value, smokiness in %) parameters of the vehicle were monitored without the additive, after adding the additive to the fuel, and then after driving 3600 km with the additive. We found a small increase in vehicle power after driving 3600 km with the additive by 1.86%, a slight reduction in fuel consumption by 4.2%, and a significant decrease in emission parameters. The NOx emissions were reduced by 9.96% after the first measurement with the additive and after the second measurement with the additive by 8.64%. The smokiness expressed by the absorption correction factor decreased after 3600 km with the additive by 35.48%, and the smokiness expressed as a percentage decreased by 33.8%. The overall impact of the additive on the power, energy, and emission parameters of the tested vehicle after analysis is evaluated as positive.
