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… Webb20 jan. 2024 · In the modern-day, the most common design for the combustion chamber inside an internal combustion engine is called a "pent-roof combustion chamber."
