Application of the biomass as a construction material of the oil filter and its influence on the performance and emission characteristics

Engine emissions can be reduced by performing suitable modifications to the oil filter. Biomass medium served as the replacement for the standard paper fibres, which are used in common oil filters. The experimental analysis of 4 emission elements showed a moderate increase in the case of 2 emission characteristics, whereby a 10% increase in monoxide was present, and also, an increase of 2.5% of nitrogen oxides was observed. Further, there was a significant reduction of 2 other emission elements, namely the unburned hydrocarbons decreased by 61%, and the amount of particulate matter was reduced by 18%. Measured engine power increased by 1.2% using the modified oil filter, which proves the success of this filter. There was a decrease in oil pressure as well, the value dropped by 0.5 bar during the whole period of the measuring process.
