Abstract: This study presents the experimental results from comparison of standard diesel fuel, pure hydrotreated vegetable oil (HVO) and a blend consisting of 30% HVO and 70% standard diesel fuel. The renewable fuel called HVO helps to reduce well to wheel emissions of CO2 and suppresses disadvantages of fatty acid methyl ester (FAME). Experiments have been done on a passenger car size single cylinder compression ignition engine equipped with a contemporary common rail injection system. Tested operating modes and procedure were based on a World Harmonized Stationary Cycle (WHSC). Common gaseous emissions, smoke number, opacity, particulate matter (PM) and particle number (PN) were measured. Weighted average of measured quantities per the test and individual modes of the test were analyzed. Results confirm positive or neutral influence of HVO on the most of measured emission components and performance parameters. The decrease in order of tens of percent was observed in case of emissions of CO, THC, PM and opacity. Emissions of NOx and CO2 decreased and power increased in order of percentage. The effect on PN was not consistent.
