Emissions of e-mobility
E-mobility is treated as emission-free. Generally, this sentence can only be true in a very small range. Namely, about selected pa-rameters 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 con-cerns 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.</jats:p
Operational energy footprint of vehicle
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.</jats:p
Statistic of fuel consumption in test and in natural operation of vehicles
The lowering of carbon dioxide emission is world pursuit which is written in international agreement. It concerns all economy sections, especially motorization. In this last case the lowering is essential, since almost all fuel used for powering vehicles comes from nonrenewable resources. Using these fuels means a one-way carbon motion from underground lode to earth atmosphere. This process has to be immediately stopped. For several years there have been taken actions in this direction. There are both legislative and technical actions. However, the reports which were published in 2016 shows that despite the efforts and engagement of considerable means, the effects are mediocre. There has been noticed, that, though the lowering of carbon dioxide emission determined in bench tests has been attained, it is impossible to notice this progress in natural operation of vehicles. The causes of such a state are sought mainly in incompatibility of test conditions to the real operation of vehicles conditions. Assuming that the carbon dioxide emission is (quasi) directly proportional to fuel consumption, in the article there has been proposed the method of solving the problem of removing divergence between test and operational data. There has been suggested the different attitude to bench data analysis and implementation of new calculative procedures in a way to reach the correlation between the test and operating fuel consumption.</jats:p

A method for energy consumption assessment by operation of bev’s in different road conditions
For the third time in the history of humankind, it is trying to implement e-mobility. There is a reasonable hope
that this attempt will succeed this time. E-mobility is generally regarded as a zero emission. This sentence can only be
true in a very small scope, as only in relation to selected parameters and in a very limited its dimension. The situation
can change radically. If it will be take into account, the emissions in the production of electricity is necessary for the
movement of this type of vehicles Second problem is the energy use amount. We know today that the energy
consumption of electric cars, especially in long-term operation is too big. This general knowledge is not confirmed by
research results. Both relevant databases and methods of their analysis are missing. This is an unfavourable situation
because it is not possible to verify the effects of various changes introduced e.g. in the construction or technology of
cars. This publication can be included in those in which it is shown how to change this situation.
The analysis of the results of long-term car use can be used as a verification of various development works, especially
in e-mobility, which is only just starting. In the future, it will be need to create the appropriate “big data” databases
and a number of tools to analyse the data collected there

A Method for Energy Consumption Assessment by Operation of BEV’s in Different Road Conditions
Abstract
For the third time in the history of humankind, it is trying to implement e-mobility. There is a reasonable hope that this attempt will succeed this time. E-mobility is generally regarded as a zero emission. This sentence can only be true in a very small scope, as only in relation to selected parameters and in a very limited its dimension. The situation can change radically. If it will be take into account, the emissions in the production of electricity is necessary for the movement of this type of vehicles Second problem is the energy use amount. We know today that the energy consumption of electric cars, especially in long-term operation is too big. This general knowledge is not confirmed by research results. Both relevant databases and methods of their analysis are missing. This is an unfavourable situation because it is not possible to verify the effects of various changes introduced e.g. in the construction or technology of cars. This publication can be included in those in which it is shown how to change this situation.
The analysis of the results of long-term car use can be used as a verification of various development works, especially in e-mobility, which is only just starting. In the future, it will be need to create the appropriate “big data” databases and a number of tools to analyse the data collected there.</jats:p
Application of the Monte Carlo method in the calculation procedure of the internal combustion engine
The aim of the work is to check the possibility of applying the Monte Carlo method to the calculation procedure of internal combus-tion 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.</jats:p
