Opis:
One of the many important challenges of the modern world is the greenhouse effect of CO2. It is necessary to implement solutions that will eliminate it. Since the easiest way to eliminate the greenhouse effect is to reduce hydrocarbons fuel consumption, it is important to evaluate the fuel (energy) consumption in long term operation. The article presents a proposal for the use of the so-called vehicle energy footprint. The method of creating such a trace is presented and illustrated with specific results of data analyzes. The data is publicly available, which means that the presented method can be independently verified. It has also been shown that the use of the method not only organizes the analyzes, but also leads to information that cannot be obtained with other methods. It therefore seems that an attractive tool has been developed for future applications.

Opis:
E-mobility is treated as emission-free. Generally, this sentence can only be true in a very small range. Namely, about selected parameters and in a very limited area. An example of this is the measurement of CO2 emissions in the immediate vicinity of BEV (battery electric vehicle). The situation can change dramatically if you take into account the emissions in the energy production necessary for car traffic. This work presents this issue taking into account the energy mix in the various countries of the European Union. Simulation research shows that there are already countries in the EU where the operation of electric vehicles makes sense. Especially when it concerns CO2 emissions. Emissions below the standards for 2025 can be obtained there. Unfortunately, in most EU countries, the operation of BEV is associated with increased (in relation to present-day) CO2 emissions. Without changing the energy policy, and in particular the energy mix, introducing e-mobility is problematic.

Opis:
The aim of the work is to check the possibility of applying the Monte Carlo method to the calculation procedure of internal combustion engines. This has been accomplished by modifying existing algorithms in such a way that the variables responsible for the main parameters of the engine are selected in a random manner using Solver written in Microsoft Excel. It turns out that this method can actually be implied, however, it has some limitations related to the high complexity of calculations.
