“…Regarding fuel, the diesel engine's fuel has the advantage of not aging. It shows the fresh and the aged surface area of the 1 wt.% Pt powder model catalysts and the mean Pt crystalline sizes evidenced by X-ray diffraction (XRD) [2]. The Zr Si, Zr Si W, and Zr Ti Si W are three components that are good for keeping fresh and are also utilized in some diesel engines, which indicates the extraordinary durability of the diesel engines, based on analysis of the lines of clothing and the aged ones.…”

These days, with the appearance and advancement of a variety of energy vehicles on the road, such as new energy vehicles, and trams, they are growing in popularity. The benefits of diesel cars have also grown in importance to individuals due to their development. The diesel engine's properties and proposals for its future development and improvement serve as the foundation for this article. The relevance and uniqueness of the diesel engine are first demonstrated by listing its important advantages. Highlight the special benefits of diesel engines and their significance, primarily by comparing diesel and gasoline engines. Then it leads to its flaws and upgrades or fixes provided by the technology and the fuel. Finally, it was determined that the diesel engine is a necessary engine that would not disappear due to the development of new technologies but rather continue to advance and gain significance through time.

“…There are also some other boundary conditions that need further testing. For example, active regeneration events, different ambient temperatures, and different fuels such as hydrotreated vegetable oil (HVO) and CNG have received high attention over the past few years [47][48][49][50][51]. We are not aware of any other study assessing PEMS for heavy-duty vehicles.…”

A heavy-duty engine is homologated in a test cell. However, starting with Euro VI regulation, the in-service conformity is controlled with the engine installed in the vehicle using portable emission measurement systems (PEMS). In Europe, the application of solid particle number (SPN) PEMS started in 2021 for compression ignition (diesel) vehicles and in 2023 for positive ignition vehicles, thus including those operating with compressed natural gas (CNG). Even though today only particles with sizes > 23 nm are regulated, the Euro 7 proposal includes particles > 10 nm. There are not many studies on the accuracy of the SPN PEMS, especially for heavy-duty applications. In this study, PEMS measuring > 23 and >10 nm from two instrument manufacturers were compared with laboratory-grade instruments. The particle detector of one PEMS was a condensation particle counter (CPC), and of the other a the diffusion charger (DC). The results showed the robustness and good accuracy (40% or 1 × 1011 #/kWh) of the PEMS for ambient temperatures from −7 °C to 35 °C, active regeneration events, different fuels (Diesel B7, HVO, and CNG), different test cycles, cold start or hot engine operations, and high exhaust gas humidity content. Nevertheless, for the DC-based PEMS, sensitivity to pre-charged urea particles was identified, and for the CPC-based PEMS, sensitivity to pressure changes with one vehicle was nnoticed. Nevertheless, the results of this study confirm that the PEMS are accurate enough to measure even the stricter Euro 7 limits.

One of the main indicators of internal combustion engines, tractors and the machine-tractor unit as a whole it's the power. It can change in the process of operation and there comes a time when subsequent use is inadmissible or inexpedient. In such a state, it is appropriate to apply technology to improve this indicator and reduce the fuel or lubricant consumption. The power parameter of an agricultural power machine is essential to achieve high productivity with low operating costs with minimal environmental pollution. The monitoring of changing the power is generally carried out by equipment unbearable and unnecessary for the farmer. The possibility for determining the power of the tractor fitted with the working machine by means of a standard brake performance device is a suitable option for monitoring the technical condition of the machinery. In this way, timely detection of defects and prevention of serious consequences for the engine. Worldwide, various technological options have been developed to improve the power of engines without the need for their disassembly. One of these technological options is the fitting of anamegators (additives) in very small quantities to the engine lubricant oil. In this article is made the experiments to evaluating of the variation of the power performance of a diesel tractor engine treated with anamegators as part of a machine-tractor unit. The acceleration and speed of the machine-tractor unit is recorded through a specialized device ENERGOTEST SM4. On this basis of the experimental results obtained, the driving force and power of the tractor from the machine-tractor unit has been determined by theoretical relationships.
