A dual overhead cam, double overhead cam, or twin-cam engine has two camshafts over each bank of the cylinder head, [1] [2] one for the intake valves and another for the exhaust valves. Therefore there are two camshafts for a straight engine and a total of four camshafts for a V engine or a flat engine.
DOHC cylinder head with intake camshaft lobe highlighted in blue. In piston engines, the camshaft is used to operate the intake and exhaust valves. The camshaft consists of a cylindrical rod running the length of the cylinder bank with a number of cams (discs with protruding cam lobes) along its length, one for each valve. As the cam rotates ...
On engines without rocker arms, such as some overhead cam and most dual overhead cam types, [1] they are known as rocker boxes in the United Kingdom. On modern engines without rocker arms they are internationally known as "valve cover" but are sometimes referred to as a "cam cover" or "timing cover" if they also cover the timing gear(s) and ...
In an overhead valve (OHV) or overhead camshaft (OHC) engine, the cylinder head contains several airflow passages called ports; intake ports deliver the fuel+air intake charge from the intake manifold to the combustion chamber, and exhaust ports route combustion waste gases out the combustion chamber to the exhaust manifold.
The dual overhead cam (DOHC) inline four-cylinder engine had 2.4 L; 144.0 cu in (2,360 cc) of displacement with a bore and a stroke of 3.46 in × 3.82 in (88 mm × 97 mm). [3] A 285 hp (213 kW) turbocharged variant of this engine was used in the high-performance SRT-4 version of the Caliber. Applications: 2007–2010 Chrysler Sebring
1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...
Harley-Davidson Twin Cam engine at the Harley-Davidson Museum. The Harley-Davidson Twin Cam are motorcycle engines made by Harley-Davidson from 1998 to 2017. Although these engines differed significantly from the Evolution engine, which in turn was derived from the series of single camshaft, overhead valve motors that were first released in 1936, they share a number of characteristics with ...
A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional ...
