“…In the majority of scientific papers, comparative studies of power systems are carried out by comparison on the basis of full load engine characteristics and performance [31,32], or in the course of tests in accordance with legislative requirements (NEDC, WLTP and RDE) [33,34]. Some publications include regulatory characteristics with varying degrees of control and different choices of analyzed parameters [35].…”

Further restrictions on the use of compression-ignition engines in transportation are prompting the search for adaptations to run on other fuels. One of the most popular alternative fuels is Compressed Natural Gas (CNG), which due to its low carbon content can be competitive with classical fuels. This paper presents the results of testing a Cummins 6BT compression ignition engine that has undergone numerous modifications to convert to CNG power. The sequential gas injection system and the ignition system were installed in this engine. The compression ratio was also lowered from 16.5 to 11.5 by replacing the pistons. Tests conducted on an engine dynamometer were to show the differences in emission and conversion in the catalyst of hydrocarbons contained in the exhaust gases. Two structurally different catalysts operating at different exhaust temperatures (400 and 500)±2.5°C were used. The catalyst operating at 500±2.5°C showed a 23.5% higher conversion rate than the catalyst operating at a lower temperature in the range of the speed range tested. Also the external indicators, such as power and torque for the case of higher operating temperature took values over 70% higher. The research is one of the stages of a comprehensive assessment of the possibility of adaptation of compression ignition engines to CNG-only fueling.

“…Despite the growing interest in electric vehicles, alternative fuels for piston combustion engines are constantly being developed. Gas fuels such as LPG for gasoline [15,16] and diesel engines [17,18], NG [19], CNG and LNG [20][21][22], various biofuels [23,24], and biodiesel from various raw materials [25][26][27][28][29][30] or hydrogenated vegetable oil (HVO) [31,32] are the examples of this progress. Another expanding field of research is related to fuel cells [33,34].…”

The aim of the research presented in the article is to use the Metalog family of probability distributions to assess the technical condition of traction battery packs from electric and hybrid vehicles. The description of the research object, which is a battery pack from a hybrid vehicle, will be provided. Then, a system for controlled charging and discharging of individual cells in a battery pack will be reviewed. It is an essential diagnostic and research device used to determine the capacity of individual cells. The capacity values of all battery cells will then be analyzed using the Metalog probability distribution family. The use of this tool allows us to determine the Probability Density Function for the entire battery pack. Based on this, the diagnostician is able to assess the technical condition of the tested package and decide on its further fate. It can be intended for repair, employed as a stationary energy storage facility, or used for disposal. The algorithm for assessing the technical condition of traction batteries proposed by the authors can be used in all battery packs regardless of the type of cells used and their energy capacity.

“…LPG, as a fuel to power vehicles, is regarded not only as a cheaper alternative to petrol or diesel fuel but also as a more environmentally friendly combustion [2]. It is also the most widely used alternative fuel in Europe, although other alternative fuels are present in the market.…”

The research aims to recognize the potential of adopting the model-based design methodology to the development process of an LPG fuelling system. Changing regulations often force the modern development of internal combustion engines (Euro 7, CO2 reduction measures, etc.). With the definitive ban on new registrations of vehicles powered by internal combustion engines in Europe (planned for 2035), there is still ongoing development of the adaptation of the fuelling system to LPG. There is still market potential in adapting new internal combustion engines, usually equipped with direct injection systems, to reduce customers’ cost of ownership of a vehicle. As the engineering process should be accelerated in the face of the variety of direct injection systems offered by OEMs, the model-based design methodology is proposed to make the development more effective. The article presents the SWOT analysis of this approach in the engineering process and the potential of the method in an LPG system development is concluded.
