The Harley-Davidson Milwaukee-Eight engine is the ninth generation of "big twin" engines developed by the company, but only Harley's fourth all-new Big Twin in 80 years, first introduced in 2016. These engines differ from the traditional Harley Big Twin engines in that there are four valves per cylinder, totaling eight valves, hence the name.
An overhead valve (OHV) engine, 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 engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead ...
The Ford Sidevalve is a side valve ( flathead engine) from the British arm of the Ford Motor Company, often also referred to as the "English Sidevalve". The engine had its origins in the 1930s Ford Model Y, and was made in two sizes, 933 cc (56.9 cu in) or "8 HP", and 1,172 cc (71.5 cu in) or "10 HP". The early engines did not have a water pump ...
Timing belt (camshaft) In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the ...
The Schrader valve (also called American valve [1]) is a type of pneumatic tire valve used on virtually every motor vehicle in the world today. The Schrader company, for which it was named, was founded in 1844 by August Schrader. The original Schrader valve design was invented in 1891, and patented in the United States in 1893.
OHC cylinder head (for a 1987 Honda D15A3 engine) An overhead camshaft ( OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber. [1] [2] This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. [3]
The valves are typically operated by a camshaft rotating at half the speed of the crankshaft. It has a series of cams along its length, each designed to open a valve during the appropriate part of an intake or exhaust stroke. A tappet between valve and cam is a contact surface on which the cam slides to open the valve. Many engines use one or ...
A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers . Camshafts in piston engines are usually made from ...
