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 .
SOHC design (for a 1973 Triumph Dolomite Sprint) . The oldest configuration of overhead camshaft engine is the single overhead camshaft (SOHC) design. [1] A SOHC engine has one camshaft per bank of cylinders, therefore a straight engine has a total of one camshaft and a V engine or flat engine has a total of two camshafts (one for each cylinder bank).
OHC 250 cu in (4.1 L) 1-bbl inline-6 (1968) The OHC 230 cu in (3.8 L) was enlarged to 250 cu in (4.1 L) for 1968 to 1969. The base engine produced 175 hp (130 kW; 177 PS) while the 4 bbl Quadrajet Sprint versions were rated up to 215 hp (160 kW; 218 PS) with automatic transmissions.
2.5 L; 152.5 cu in (2,499 cc) straight-four, with two (pushrod-actuated) valves-per-cylinder and indirect fuel injection. 92 mm × 94 mm (3.62 in × 3.70 in), the engine size is variably referred to as either 2,500 or 2,499 cc. This engine too has been called HR 492, signifying four cylinders of 92 mm (3.62 in) bore. Timing gears, not belt.
Though it was designed as a pushrod engine, it was advanced for the time. [1] The pushrod version of the Lancia boxer was only ever used in the Flavia, and its derivatives including the Lancia 2000. In 1976, a new overhead cam engine based on a similar layout was designed and brought into production in 2 and 2.5-litre displacements for the Gamma.
The Mitsubishi Saturn or 4G3 engine is series of overhead camshaft (OHC) straight-four internal combustion engines introduced by Mitsubishi Motors and saw first service in the 1969 Colt Galant. Displacement ranges from 1.2 to 1.8 L (1,239 to 1,755 cc), although there was also a rare 2-litre (1,994 cc) inline-six version built from 1970 until 1976.
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 ...
The location of the camshaft drive in the center made it necessary to have four main bearings instead of the usual three. Tubular connecting rods were also used, which was a very advanced idea for its day. [4] Weidely produced a three main bearing pushrod ohv six that powered the Auburn 6-63 models of 1923 and 1924. Unlike most pushrod designs ...
