WebThe crossection sketch of the combustion chambers compares the shape of a stock head (dashed lines) and Ricardo head. The Ricardo design employs a small clearance over the piston and a larger cavern around the valves for good air flow. For best results, the clearance above the piston should be 0.050 to 0.080 inches (Huntington, p. 70). WebOct 4, 2010 · The combustion chamber is not only the combustion chamber, it's also the "port" that lets air go from the intake valve to the cylinder, and out to the exhaust valve. To get high compression in a flathead you have to reduce the size of the chamber so much that it impedes flow.

WebThere are really three types of OHV heads: the L-head (also known as the flathead), the I-head, and the F-head. The valves are placed within the engine block alongside the cylinders on flathead engines. The advantage of these heads in comparison to OHC versions is that they are arguably simpler in design. 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 separate …
