The article describes the processes that take place in an engine. The main terms connected with the compression ratio are explained. Moreover, the relationship between the compression ratio and the engine efficiency is discussed. This paper is a repetition of issues connected with functioning of the engine. In this article, variables that influence the chart are described, along with some examples of the way to increase engine efficiency. This article focuses on selected methods of improving efficiency of internal combustion engines. In order to fully understand processes taking place in the combustion chamber, it is necessary to create theoretical charts of thermal cycles and, then, to compare them with actual charts obtained as a result of measurements. The structure of contemporary engines is influenced by various factors, for example preservation of natural environment or limited fuel resources. These factors are crucial for mechanical engineering and engine design. Therefore, energy consumption and environmental impact of engines are taken into consideration when researching new ways and methods of enhancing engine efficiency. One of the main aims of the researchers and engineers is to reduce the emission of carbon dioxide (CO2), carbon monoxide (CO), hydrocarbons (HC) and oxides of nitrogen (NOx) in exhaust fumes. Improved engine efficiency, lowered fuel consumption and reduced emission of toxic substances are the main advantages of internal combustion engines characterized by variable compression ratio.
