10 Facts About Internal combustion

An internal combustion engine is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit.

In 1807, French engineers Nicephore Niepce and Claude Niepce ran a prototype internal combustion engine, using controlled dust explosions, the Pyreolophore, which was granted a patent by Napoleon Bonaparte.

Where high power-to-weight ratios are required, internal combustion engines appear in the form of combustion turbines, or sometimes Wankel engines.

Base of a reciprocating internal combustion engine is the engine block, which is typically made of cast iron or aluminum.

Internal combustion engines require ignition of the mixture, either by spark ignition or compression ignition .

The temperature of the compressed air is further increased by Internal combustion of injected fuel in the Internal combustion chamber which expands the air.

Notably, the Internal combustion takes place at constant pressure, rather than with the Otto cycle, constant volume.

All internal combustion engines depend on combustion of a chemical fuel, typically with oxygen from the air .

Internal combustion engines are considered heat engines and as such their theoretical efficiency can be approximated by idealized thermodynamic cycles.

Internal combustion engines continue to consume fuel and emit pollutants when idling so it is desirable to keep periods of idling to a minimum.
