WebFig.3 Combustion chamber IV. COMBUSTION PROCESS Air from the engine compressor enters the combustion chamber at a velocity up to 500 feet per second, but because at this velocity the air speed is far too high for combustion, the first thing that the chamber must do is to diffuse it, i.e. decelerate it and raise its static pressure. chinguacousy and bovaird

Combustion-Chamber Design in Theory and Practice

In an internal combustion engine, the pressure caused by the burning air/fuel mixture applies direct force to part of the engine (e.g. for a piston engine, the force is applied to the top of the piston), which converts the gas pressure into mechanical energy (often in the form of a rotating output shaft). This contrasts an external combustion engine, where the combustion takes place in a separat… WebThe engine's main combustion chamber (MCC) receives fuel-rich hot gas from a hot-gas manifold cooling circuit.
