“…By 2050, a 60% reduction in emissions of carbon dioxide in the transport sector in the EU is being promoted and one from more ways is the using of new fuels especially with hydrogen content also in form as the hydrogen is in water. From this reason are important to know if that is possible with water-hydrocarbons fuel mixture [4,5,10,14].…”

The recent development of internal combustion engines (ICE) goes towards the meeting of increasingly stringent requirements imposed to reduce toxic exhaust emissions and fuel consumption and thus to strive for carbon dioxide abatement and against depletion of global natural resources. The research on engines fuelled by water-hydrocarbons emulsions has already a long tradition. So far, tests were based on emulsions obtained in chemical reactions. In this paper, similar analysis results have been presented, but the water-fuel emulsions used for the tests were obtained with making use of the cavitation effect. For this reason a unique cavitator was developed, which was then used to produce water-hydrocarbons emulsions of common, mineral and synthetic diesel fuel. Both of these fuels as well as their water emulsions with 20% water content by volume, were used for tests. The ESC (European Stationary Cycle) test conditions were determined and the engine was tested on engine dynamometer in accordance with the predetermined ESC test conditions. During the tests, under close scrutiny, engine emission and fuel consumption levels were measured . The tests it be more time repeat (with every liquid to engine fuelling was 34 times) to achieve the statistical assessment of the results. By the use of emulsions was found to result in a significant reduction in the consumption of diesel fuels . This result is statistically significant.

“…Automotive industry has a very diverse impact on the environment. You can divide it into beneficial effects, mainly sociological and civilization, and adverse effects such as air pollution from exhaust fumes, effects causing vibration and noise, or leaks [7,8]. Subjects of environmental impact are primarily: motor vehicles (cars, trucks, buses, etc.…”

The largest amount of air pollutants is produced by the combustion of fossil fuels (coal, lignite, petroleum, natural gas, etc.). Such combustion releases huge amounts of greenhouse gases into the atmosphere (including carbon oxides (CO, CO2), sulphur oxides (SO2, SO3), nitrogen oxides (NO, NOx)) and dust, ashes and soot. Transportation is a significant share of the air pollution, mainly wheel-based transportation.The combustion process in diesel engine is very complex physico-chemically and varies in time. The process is accompanied by simultaneous exchange of heat and mass and chemical reactions.The development of internal combustion engines is made towards meeting of the increasingly stringent requirements for toxic exhaust emissions, reduction of fuel consumption, and preservation of Earth's natural resources.The problem to solve in modern diesel engines is the emission of toxic compounds. One way to reduce emissions is to use a catalytic converter positioned directly in the combustion chamber of an internal combustion engine.The aim of this analysis is assessment of toxic emissions of a diesel engine with an internal catalyst. Qualitative assessment of engine emissions was determined by comparing test results of an engine with ceramic-ally coated valves against one with just conventional valves (commercial valves -without a ceramic coating). The study utilized a fourcylinder 1.9 TDI VW engine. It was expected that the use of glow plugs with an active coating would reduce the release of toxic compounds.
