- It is oblivious, various properties of fuels cause different thermal loads of engines. Question is, how big is this effect and what fuel compound and its property play insignificant part. This paper is focused on problem of quality of diesel commercial fuels in Polish market and it is a challenge to find answer for question mentioned above. The academic staff from Wroclaw University of Technology organized tests with different commercial fuels. Chemical and physical properties of these fuels were studied and used for investigation to define relationships between them and thermal load during simulation process. All researches were done in the lab of Division of Motor Vehicles and Internal Combustion Engines at the Wroclaw University of Technology. Tests have showed differences in chemical and physical properties of fuels, but there is no statistics effect on engine parameters. Results have not also pointed any important differences in thermal loads of engine VW1,9 TDI and its components according to different physical and chemical properties of tested fuels. It is probably because there are differences of calorific values from one side but from other hands various density and specific fuel consumption compensated these differences. To burn unit of fuel contains higher level of oxygen, engine needs lower amount of air, so it gives, for the same fuelling system, lean mixture. It causes higher temperature of exhaust gases and a bit higher exhaust losses
