“…Thus, the engine power and torque increase did not automatically and always mean an increase of the amount of fuel consumed, too. The reason is that the combustion efficiency is being increased and, thus, the specific fuel consumption is being reduced [19].…”

“…Tables 14, 15 and 16 shows the percentage of fuel consumption change measured before and after data adjustment. Since there were neither any modification of transmission mechanical efficiency nor of the driving speed, the results in percentage are valid for both, a change of fuel consumption needed for driving a certain distance and a change of BSFC [17][18][19]. For better transparency, the results are also shown in the form of graphs, Fig.5.…”

Data stored in the memory of the engine control unit can be adjusted and modified in order to change some vehicle features. The purpose of the article is to determine the impact of such adjustments in the engine control unit on selected vehicle characteristics. These include the engine power and torque depending on the engine speed and fuel consumption. The measurements were performed under laboratory conditions in order to achieve the highest possible accuracy. The results show the possibilities of dynamic vehicle characteristics' improvement without having specific impact on the fuel consumption. ARTICLE HISTORY

Climate change and the associated global warming affect all of us. These changes cause the melting of the glaciers and consequently the increase in sea and ocean levels. This phenomenon threatens the existence of some of the island states. The warming casing all this was brought on by the economic activity of humans, with the greatest responsibility being attributed to the ever-increasing production of greenhouse gases. Transport generates large portion of these gases. When means of transport are in motion, they are affected by certain driving resistances which try to keep vehicle from moving. In order to overcome them, it is necessary to produce certain useful work equivalent to the measurement of driving resistances. An internal combustion motor is the most frequent source of such energy. It generates energy by oxygenating hydrocarbon fuels, and in addition to the useful work, it produces also unfavourable emission. The amount of such emissions equals to the amount of burnt fuel. Thus, levels of emissions can drop by reducing fuel consumption. The most commonly mentioned gas is the CO2. Reduction of CO2 production is essential to affect the high level of CO2. The article focuses on the possibilities of reducing CO2 from road transport. The possibilities of reducing CO2 from road transport are quantified in the form of mathematical model calculations.

“…The use of plastic materials for the production of motor vehicle parts also contributes to the reduction in mass as well as fuel consumption and emissions of harmful gases. Therefore, almost one-third of car parts are made of plastic, which consists of various polymer materials [43,44]. From that aspect, it is very important that the recycling of plastic parts takes place properly in accordance with the standards.…”

Regardless of the increasingly intensive application of vehicles with electric drives, internal combustion engines are still dominant as power units of mobile systems in various sectors of the economy. In order to reduce the emission of exhaust gases and satisfy legal regulations, as a temporary solution, hybrid drives with optimized internal combustion engines and their associated systems are increasingly being used. Application of the variable compression ratio and diesel fuel injection timing, as well as the tribological optimization of parts, contribute to the reduction in fuel consumption, partly due to the reduction in mechanical losses, which, according to test results, also results in the reduction in emissions. This manuscript presents the results of diesel engine testing on a test bench in laboratory conditions at different operating modes (compression ratio, fuel injection timing, engine speed, and load), which were processed using a zero-dimensional model of the combustion process. The test results should contribute to the optimization of the combustion process from the aspect of minimal particulate matter emission. As a special contribution, the results of tribological tests of materials for strengthening the sliding surface of the aluminum alloy piston and cylinder of the internal combustion engine and air compressors, which were obtained using a tribometer, are presented. In this way, tribological optimization should also contribute to the reduction in particulate matter emissions due to the reduction in fuel consumption, and thus emissions due to the reduction in friction, as well as the recorded reduction in the wear of materials that are in sliding contact. In this way, it contributes to the reduction in harmful gases in the air.
