Review on Types of Engineering Machinery Engines and their Classifications

Abstract

Engines in any machine represent the cornerstone of operating any machine. Internal combustion engines differ slightly from external combustion engines such as steam engines and Stirling engines, which contain a working fluid that obtains energy from an external source (example: burning coal to heat boilers to obtain the necessary steam (for the engine). The fluid is not part of the combustion products or mixed with them. The working fluid is heated in a boiler, and the working fluid can be air, hot water, pressurized water or even liquid sodium. Internal combustion engines are often powered by high-energy liquid fuels derived from Fossil fuels. Most internal combustion engines are used in mobile applications as well as many stationary applications. The power, quality and efficiency of engines of machines and cars in the world vary according to the purpose of their manufacture, and whether they are intended for sports cars, family cars or four-wheel drives.
