The article analyzes the influence of physicochemical properties of selected hydrocarbon fuels on the injection process in a compression-ignition engine. An attempt was made to determine to what extent the kinematic viscosity index, density, and surface tension of fuels can affect the injection process. A number of fuel injection parameters were determined, such as: maximum injection pressure, start of injection angle, end of injection angle, and injection duration angle. The results of the work are interesting from the point of view of the operation of traction vehicle power units.Stricter standards regarding the emission of toxic exhaust compounds and the unstable situation in the petroleum fuel market force research into new types of fuels for internal combustion engines. With regard to compression-ignition engines, this research is being conducted in three main directions [3]:
• searching for fuels not derived from crude oil, • searching for fuels (diesel additives) that can be used in mixtures with diesel fuel;
• modifying the chemical composition and physicochemical properties of diesel fuel at the production stage.
In the first group of fuels, those derived from oilseeds deserve special attention. In Polish conditions, this is rapeseed oil. In other climatic regions of the world, soybean oil, palm oil, and peanut oil are used. These oils, with certain limitations, can be used as pure fuel or as additives to diesel fuel. (…)
