R ENVIRONMENTAL AND ECONOMIC EFFECTS OF FUEL ADDITIVES
Today’s public transportation still actively uses buses with outdated diesel engines that require significant investment for renovation and upgrading to facilitate modern filters. Possible solution is found in using additives based on saponified naphthenic acids, aliphatic hydrocarbons and copper. Utilizing these additives accelerates the engine's combustion process, reducing carbon and other exhaust gasses emission, carbon monoxide and particulate matter as well as fuel consumption, resulting in increased fuel economy. Author’s primary goal was to determine effects of additive utilization on fossil fuel combustion, emission of exhaust gases along with possible effects on fuel economy. Research was conducted in two cycles on public transport buses, one of an older type and one of the newer type. Data on fuel consumption was collected without additives for the first cycle and with fuel additives on the second one.
