Internal combustion engine - Wikipedia

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.

Pressure gauge - WIKA

Pressure gauges with open connecting flanges are even suitable for highly viscous and contaminated media, in aggressive environments too. Depending on the instrument model and pressure range, an overload safety of 3x or 5x the full scale value is standard. This overload safety is also possible for 10, 40, 100 or 400 bar special designs.
