WebbThe combustion chamber of the engine was pent-roof shaped with a 42-degree intake to exhaust valve angle and a nearly centrally located spark plug (Fig. 5a). The corresponding finite-difference grid used in the KIVA code is given in Fig. 5b. The procedure for generating the finite-difference grid is summarized in [8]. Table 1 - Pent-Roof Engines 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… Webb28 sep. 1999 · Two-valve pent-roof type combustion chamber was employed for four stroke cycle small utility engine.
