An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines , where the valves were located below the combustion chamber in the engine block .
Part of the Hercules DFX series, the DFXE is a naturally aspirated, direct injection,overhead valve, inline six-cylinder engine. [ 1 ] [ 2 ] The engine had a displacement of 855 cu in (14.011 L), with a bore of 5 + 5 ⁄ 8 in (143 mm), a stroke of 6 in (150 mm) and a compression ratio of 14.8:1.
In an overhead valve engine the tappets (on right) are sandwiched between pushrods and the camshaft. In an internal combustion engine, a tappet (also called a 'valve lifter' or 'cam follower') [3] [4] [5] is the component which converts the rotation of the camshaft into vertical motion to open and close an intake or exhaust valve.
There were also four-cylinder engines based on the D-Series six cylinder engine in various capacities using common parts from 2199-2660cc petrol to 2178-2520cc diesel known initially as the 2.2-litre Austin BS1 OHV.
Cutaway of a dual overhead camshaft engine 1969 AMC V8 overhead valve engine. The rocker cover has been removed, so the pushrods, rocker arms, valve springs, and valves are visible. A valvetrain is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. [1]
The most common use of a rocker arm is to transfer the motion of a pushrod in an overhead valve (OHV) internal combustion engine to the corresponding intake/exhaust valve. In an OHV engine the camshaft at the bottom of the engine pushes the pushrod upwards. The top of the pushrod presses upwards on one side of the rocker arm located at the top ...
