Abstract: The report examines the trends in the development of the internal combustion engine market in the time of growing requirements for the content of pollutant in the exhaust gases. The current EU legislation and its future modifications regulated in EURO 6d TEMP, in order to more accurately take into account the content of pollutant and CO2 is analyzed. On this basis, there are forecasts of the produced vehicles with different propulsion up to 2025.Most serious attention is paid to the place of electric cars in the future market. They are considered not only towards their positive sides - low pollution of the environment and low energy costs. Several of their disadvantages and potential negative consequences from their mass production are pointed out. An analysis of the automotive market in Bulgaria and the environmental problems, which follow from its structure and age is made.
Abstract: The lowering of carbon dioxide emission is world pursuit which is written in international agreement. It concerns all economy sections, especially motorization. In this last case the lowering is essential, since almost all fuel used for powering vehicles comes from non-renewable resources. Using these fuels means a one-way carbon motion from underground lode to earth atmosphere. This process has to be immediately stopped. For several years there have been taken actions in this direction. There are both legislative and technical actions. However, the reports which were published in 2016 shows that despite the efforts and engagement of considerable means, the effects are mediocre. There has been noticed, that, though the lowering of carbon dioxide emission determined in bench tests has been attained, it is impossible to notice this progress in natural operation of vehicles. The causes of such a state are sought mainly in incompatibility of test conditions to the real operation of vehicles conditions. Assuming that the carbon dioxide emission is (quasi) directly proportional to fuel consumption, in the article there has been proposed the method of solving the problem of removing divergence between test and operational data. There has been suggested the different attitude to bench data analysis and implementation of new calculative procedures in a way to reach the correlation between the test and operating fuel consumption.

Abstract: In this article, based on a study analyzes the operation of the 2 cylinder 4-stroke engine 7,2/6 with spark ignition and external mixture formation on gasoline with additives of synthesis gas. Given the indicator diagram when the engine working on a load characteristic with additives of synthesis gas – 25…65%. It has been established that with the amount of synthesis gas added to gasoline in the range 25...65% - the relative heat release rate grow up 7...16%. The feasibility of using synthesis gas additives to gasoline has been economically confirmed. Hourly savings when operating a gasoline engine with synthesis gas additives (25 ... 65%) is 24 ... 48% of the cost of gasoline.
Key words: synthesis gas, bioethanol, gasoline, the indicator diagram, the internal combustion engine, additives synthesis gas.
