Thesis represents the possibility of using pyrolysis oil, produced from waste tires, in a modern turbo charged and intercooled automotive diesel engine with a common rail system. Due to the low cetane number of used fuel, direct use in a diesel engine was until now limited only to high loads. The thesis demonstrated that by changing the fuel injection parameters, introducing the pilot injection and recirculated exhaust gases it is possible to extend the working area of the diesel engine using 100% pyrolysis oil, produced from waste tires. For measurement purposes, an experimental rig was designed to measure thermodynamic parameters and emissions. The results of the measurements indicate that a modern turbo charged and intercooled automotive diesel engine with a common rail system can efficiently operate with the use of direct pyrolysis oil produced from waste tires even at medium and low loads, while ensuring gaseous emissions comparable to level emitted with diesel fuel.
