Comparative analysis of the energy consumption of cars with different power plants

Abstract

A comparative analysis of the energy costs of cars with different power plants is carried out. The main advantages and disadvantages of comparable vehicles are considered. Problem. To date, economic and social problems remain global in Ukraine. Air pollution by harmful substances is a very serious concern not only for environmentalists, but for the whole of humanity. The significant drawbacks of a conventional internal combustion engine, namely, exhaust emissions, reduced oil and gas reserves, the constant rise in the cost of motor fuel, are forcing vehicle manufacturers to actively pursue alternative clean energy sources. Goal. The purpose of this work is to perform a comparative analysis of the energy performance of cars with different power units. To achieve this goal it is necessary to solve the following tasks: to consider the energy consumption figures of cars with different power units and compare them; to reveal the main advantages and disadvantages of cars with different drive type. Results. The analysis of publications shows that the use of environmentally friendly car is a modern and promising direction for the development of road transport. The most competitive and effective circuit solution for the construction of such a car today is the use of a hybrid power plant and electric drive. This article provides a comparative analysis of the energy performance of cars with different power units. According to the analysis, the most efficient in terms of energy consumption is the Nissan Leaf electric car – 105 kWh, but when using this car over long distances, it reduces its average operating speed due to downtime at charging stations. The Toyota Corolla, with its traditional gasoline engine, has the highest energy consumption rating of the entire journey – 450 kWh. The Toyota Prius hybrid car has a clear advantage over these cars when used over a long distance of 500 km of energy – 160 kWh, he also has the largest range of 1300 km at one gas station and overcomes this path in 21,6 hours.
