Improving Heavy Duty Vehicles Fuel Consumption with Density and Friction Modifier

  • Máté ZöldyEmail author


With the increasing role of electro mobility it is predictable that for heavy duty sector it would not be able to replace the traditional engines. There are several researches to develop alternative propulsion solutions but in short term the efficiency improvement of diesels both in engine and fuel side is a must. In this research paper the main influencers of diesel fuel composition on combustion is investigated based on literature overview. Our research is focusing as most important parameters the density and friction. Different sample fuels were prepared to show how these parameters influencing fuel consumption in engine bench measurements. Our results showed that both with density and modification of friction are tools to improve fuel.
