An internal combustion engine is a machine that obtains mechanical energy directly from the chemical energy consumption of fuel burned in a combustion chamber, which is an integral part of an engine.
In 1867, in Germany, the Otto engine with free piston was developed by Nicolaus August Otto (1832-1891) and Eugen Langen (1833-1895), based on the burning of a mixture of air and fuel by a gas flame inside a cylinder. Such an engine achieved a thermal efficiency of 11%. After evolutions in the functional aspect aiming at greater thermal efficiency, Otto, in 1876, managed to develop the engine based on four strokes - admission, compression, expansion or power and discharge. A motor with reduced weight and volume and great thermal efficiency was obtained. This was the advance that effectively founded the internal combustion engine industry, leading to current engines powered by gasoline, alcohol and natural gas for vehicles (CNG).
A few years later, in 1892, Rudolf Diesel (1858-1913) developed a different engine, in which a high compression ratio was used to burn fuel. The fuel was injected towards the end of the compression stage where it was then burned by the highly heated compressed air. The efficiency of this engine was increased due to the high compression ratio and expansion ratios. The current diesel engine is designed on the same operating principle and is developed in four strokes and two strokes.
