Nowadays problem of environment pollution reduction is of current interest. Is- sue connected to environment pollution due to harmful emissions caused by internal combustion engine requires attention. Plane pollutes environment with harmful emissions and noise that are caused by internal combustion engine. Harmful emissions have negative influence on environment that can lead to climate change meanwhile it has a negative impact on vital activity of human beings and fauna. Stages of implementation analysis: a) analysis composition of aviation engines emissions and mechanism of influence on atmosphere and human has been revealed; b) comparison of ecological point of view connected to recent modifications of long-haul jet aircraft Boeing 747 and Airbus A380; c) analysis composition of aviation noise and consequences of living organisms influence. In order to reduce negative influence on atmosphere from aviation sector, IKAO reduction of emission quantity method and emitted noise has been created. Method is based on strengthening of quantitative criteria for new certificated aircrafts in comparison to recommendations that are valid nowadays.

Introduction. The use of an electromechanical transmission in the design of a tracked vehicle allows an increase in the complex indicator of mobility, an increase in the range, fuel efficiency, maximum speed, a decrease in acceleration time, etc. The improvement of these indicators is achieved mainly due to the different performance characteristics of the internal combustion engine and the energy characteristics of electrical machines. The latter fact makes it possible to ensure the operation of the power plant of the tracked vehicle in such a way as to avoid unfavorable operating modes of both the internal combustion engine and the elements of the electromechanical transmission (a generator, a traction electric motor, an energy storage) from the point of view of energy efficiency, and to realize the high efficiency of the entire system.Research methods. To improve the mobility and implement a rational strategy for electromechanical transmission control, it is necessary to have an idea of the effective modes of operation of the main elements of the power plant. As a way to solve this problem it is proposed to study the energy characteristics of the main elements of an electromechanical transmission using the developed mathematical model for various modes of movement of a tracked vehicle.Results. Modeling the motion of a tracked vehicle with an electromechanical transmission makes it possible, in addition to determining the transmission parameters, to formulate preliminary requirements for its characteristics.Discussion and conclusion. To solve these problems, it is necessary to simulate the process of movement of a tracked vehicle, taking into account the initial data that are adequate to real operating conditions.

Abstract The tremendous growth in the transportation sector as a result of changes in our ways of transport and a rise in the level of prosperity was reflected directly by the intensification of energy needs. Thus, electric vehicles (EV) have been produced to minimise the energy consumption of conventional vehicles. Although the EV motor is more efficient than the internal combustion engine, the well to wheel (WTW) efficiency should be investigated in terms of determining the overall energy efficiency. In simple words, this study will try to answer the basic question – is the electric car really energy efficient compared with ICE-powered vehicles? This study investigates the WTW efficiency of conventional internal combustion engine vehicles ICEVs (gasoline, diesel), compressed natural gas vehicles (CNGV) and EVs. The results show that power plant efficiency has a significant consequence on WTW efficiency. The total WTW efficiency of gasoline ICEV ranges between 11–27 %, diesel ICEV ranges from 25 % to 37 % and CNGV ranges from 12 % to 22 %. The EV fed by a natural gas power plant shows the highest WTW efficiency which ranges from 13 % to 31 %. While the EV supplied by coal-fired and diesel power plants have approximately the same WTW efficiency ranging between 13 % to 27 % and 12 % to 25 %, respectively. If renewable energy is used, the losses will drop significantly and the overall efficiency for electric cars will be around 40–70% depending on the source and the location of the renewable energy systems.

Hybrid Power Plant

The problem of control of a hybrid power plant of a car consisting of an internal combustion engine, a synchronous electric motor with permanent magnets and a synchronous generator is considered. The formation of the control effect is carried out taking into account the connection of the above objects with each other with the help of planetary transmission. The mathematical models of the three listed engines are nonlinear with several control channels. In addition, the principle of the hybrid power plant requires the simultaneous operation of these engines and, accordingly, the construction of the necessary interrelated control actions. To synthesize the laws of vector control of a hybrid power plant, the method of analytical construction of aggregated regulators (ADAR) is used. Within the framework of this method, it is possible to work with a complete nonlinear control object model. Unlike the traditional approach of constructing a separate stabilizing control for each control channel, this method uses co-control over all variables to transfer the object to the desired state. In this case,for a number of variants of control algorithms, the communication between the control channels is carried out not indirectly, through the control object, but directly formed in the regulator. In addition, the control law takes into account unknown external disturbances, which were compensated using the principle of integral adaptation. In this paper, one of the modes of operation of a hybrid power plant is shown during the acceleration of the car. First, only the electric motor works, as the car accelerates, the internal combustion engine is connected, and at high speeds only the internal combustion engine works. This mode of operation of the hybrid power plant allows using both engines in the most convenient range of angular speeds, which leads to an economical fuel consumption and a charge of the storage batteries. In addition, the second electric motor operates in the generator mode and transfers a part of the mechanical moment to recharge the batteries.
