Studies of Engine Performance and Emissions at Full-Load Mode Using HVO, Diesel Fuel, and HVO5

The aim of the study was to determine impact commercially available hydrotreated vegetable oil (HVO) and its mixture (HVO5, where 5% (v/v) HVO 95% FDD) with diesel fuel (FDD) on power, torque, consumption, exhaust gas composition an atmospheric internal combustion engine used in off-road applications. Diesel as comparative fuel. Testing realized a full-load mode KOHLER KDI 1903 M 3-cylinder SIERRA CP-Engineering test bench. AVL SESAM FTIR analytical system emissions, while KMA Mobile consumption measuring device measure consumption. Research showed that lowest power torque readings were obtained FDD, slightly higher result compared fossil At same time, highest hourly observed running HVO5, FDD. Increases carbon monoxide (CO), dioxide (CO2), nitrogen oxide (NOx) emissions for HVO5 those CO content increased by average 3.0% using 36% but NOx 8.8% HVO5. reduction 60% found case hydrocarbons (HC). confirmed physicochemical properties could leave main performance parameters emissions.
