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… WebPull-through system — the products of combustion are pulled through the combustion chamber for increased radiant efficiency and greater safety; CSA design certified for vertical or horizontal venting; CSA design certified for maximum 75 ft. horizontal sidewall venting; 4″ O.D. flue connection for LTU40-LTU175; 6″ for LTU180-LTU250 onofre services
