“…As of January 1, 2021, this limit has been lowered to 95 g/km. The reduction in average CO 2 emissions of 95 g/km is the strictest in the world [4]. For comparison -in 2021 this limit in the United States was 125 g/km, in Japan it was 122 g/km and in China it was 117 g/km [5].…”

The article presents the laboratory tests results of the influence of the diesel oil content in a mixture with rapeseed oil on the operating parameters of a diesel engine with the common rail fuel supply system. Fuel mixtures with a rapeseed content of 0, 50, 70, 100% were used. The article presents the results of tests carried out for various configurations of the object. The measurements included tests of exhaust gases: the content of carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides as well as specific fuel consumption and exhaust gas temperature. As a result of the research, it was noticed that the use of rapeseed oil causes a significant increase in fuel consumption and an increase in emissions. At a crankshaft speed of 2500 rpm and a torque generated by the engine crankshaft of 12 Nm, the specific fuel consumption for a 0% rapeseed content is 310 g/kWh. For the same engine operating conditions and the same rapeseed content of the fuel, the fuel consumption for 100% rapeseed content is 330 g/kWh.For the same engine operating parameters, analysis of the carbon dioxide content in the exhaust gas yields a value of 7.8×10 4 ppm for a rapeseed content of 0%. For the same engine operating conditions and for the oilseed rape content in the fuel is 100% 8.4×10 4 ppm. The mathematical models describing the effects of engine operating parameters and rapeseed oil content in the mixture on the observed values were created with the Scilab program. The degree of agreement of the determined mathematical models was checked by calculating the coefficient of determination (R2). The results are shown in 3D figures.

“…The design of structural components should take into account the production process of the material and select materials that produce less pollution [11,12]. Over the years, we have invested heavily in solutions related to electrification in order to improve the efficiency of machinery and equipment [13,14], and we have also made great efforts to improve the performance of engines [15]. To reduce carbon dioxide emissions, new and high-performance materials are used to operate on these mechanical components [16,17].…”

Through the comparison of fatigue properties of components made of composite materials and high-strength structural steel materials, this study proves that composite materials can replace traditional steel materials used in the production of mechanical structural components. The focus of this study was a low-speed, high-torque radial piston motor mounted on a roadheader. According to different theories, the motor block was designed using a composite material made of carbon fiber, a classic high-strength structural steel, and an aluminum alloy. The thickness of the motor cylinder obtained by theoretical calculation was verified by finite-element numerical simulation technology, and the fatigue phenomenon caused by the time change of the piston cylinder pressure was considered. The results showed that the stress results of the numerical simulation verify the rationality of the theoretical calculation of the cylinder size. In terms of safety factors, the motor cylinder made of composite materials was close to the motor cylinder made of high-strength structural steel, and the difference between the static safety factor and fatigue safety factor was only 0.8 and 0.86. The weight of the motor cylinder made of composite material was reduced from 32 N to 7 N compared with steel material, which was about 78% lighter. This is of great significance for improving the use efficiency of equipment and reducing fuel costs.

“…Nevertheless, none of these methods considers the trade-off between the energy efficiency of a vehicle-tailored design against the significant manufacturing cost reduction prompted by designing shared modules serving a whole family of vehicles. The application of product family design concepts to hybrid electric vehicles can be found in one recent paper [33], where the author proposed a tool to compare different topologies and sizes from a predefined set to minimize the costs for the manufacturer. However, the algorithm can only compare a limited number of size values from predefined sets for each component in the powertrain, and the cost model does not consider the savings owing to the EoS effects.…”
