“…Paper [55] examined the energy consumption of a PHEV hybrid car in different seasons, which also confirms another important factor, i.e., meteorological conditions, which have a significant impact on the results obtained in real driving conditions. It has been confirmed that the lowest energy consumption occurs in summer, while the highest consumption occurs in winter conditions.…”

Differences between the results obtained in laboratory and road tests of vehicles depend on a number of factors. Among the most important of these are driving cycle and road load. These parameters also affect the hybrid drive control, including the combustion engine operation or driving in electric mode. In most studies, tests carried out on chassis dynamometers concern type approval cycles (NEDC—New European Driving Cycle, WLTC—World-wide harmonized Light duty Test Cycle, FTP— Federal Test Procedure), which differ from real on-road tests. Consequently, the different driving cycles do not allow for results similar to those obtained during on-road driving, especially as the actual cycles on the road are unrepeatable. It is also important to determine the effect of the motion resistance function adopted for chassis dynamometer tests on exhaust emissions and fuel consumption. For this purpose, the authors tested a hybrid car under road and laboratory conditions for the same driving cycle. The analysis was conducted for an example urban road cycle in Rzeszow (URRC). The purpose of the study was to determine the differences in the results of gaseous emissions (THC, CO, CO2, NOx) and fuel consumption (energy) of a hybrid car under road conditions, with the results of tests conducted on a chassis dynamometer, for the same cycle and three functions of resistance.

The aim of the article is to analyze the impact of operation on the life cycle assessment of city buses with diesel and electric drive using neural networks based on source data. Two types of diesel buses and two types of electric buses were tested. As a result of the conducted tests, the following optimal values were obtained for buses: operation time, number of inspections, daily refueling time or battery charging time, general efficiency, emissions. The adopted values of the life cycle assessment criteria are optimal for electric and electric city buses. The presented research and analyzes have a significant impact on the processes related to the organization of public transport.

The aim of the article is to present a computational model to determine the losses generated by the brake discs of rail vehicles. The energy consumption of the disc (energy losses) is divided into inertia losses and fan losses. The article is preceded by a review of the design solutions of brake discs of rail vehicles in terms of their ventilation and cooling after braking. Particular attention was paid to three types of brake disc designs with ventilation blades, bars and other shapes of ventilation bridges, and how the ventilation of these discs affects energy losses. On the one hand, forced ventilation of brake discs shortens the cooling time after intensive braking, on the other hand, it causes energy losses due to forced ventilation when the brakes are not used. The article presents the state of knowledge regarding the cooling efficiency of brake discs as a result of forced ventilation and presents a method for calculating the energy consumption generated by the brake disc in relation to the rotational speed. The energy losses were divided in the article into inertia losses due to the rotating mass and losses on the fan, in which the energy necessary for the rotation of the brake disc was determined from the method of calculating centrifugal fans with known geometric dimensions.
