Opis:
This paper is focused on problem of quality of diesel commercial fuels in Polish market and an effect of their properties as well on engine parameters as environment The academic staff from Wrocław University of Technology put the own experience to the huge discussion by making research in the Wroclaw-city, where some probes of fuels were taken from six different commercial fuel stations. Chemical and physical properties of fuels were checked. A real diesel engine VW 1,9 TDI was investigated in university lab of Division of Motor Vehicles and Internal Combustion Engines. Typical engine performances were built including power, torque, fuel consumption, toxicity levels due to different fuels. The IC engine on the test bench, oxygen content in fuels, example of full load performance of VW1,9 TDI for fuel Bio D20-type, differences of mean effective pressure for different fuels, differences of carbon monoxide in exhaust for different fuels, differences of nitric oxides in exhaust for different fuels, differences of smog level in exhaust for different fuels, differences of heat release for different fuels, relation between engine torque and oxygen content in fuels vs. engine rotation are presented in the paper.

Opis:
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

Opis:
The issues discussed in the article include exhaust gas emission, purity requirements and standards, methods of reducing the emission of harmful exhaust gas components, and alternative and future traction drive sources having the form of fuel cells. The discussion often refers to the situation of road transport, a subsystem which severely affects the environment and thus is obliged to intensify the search for solutions.
