Adria (motorcycle)
The Adria company were better known for their motor vehicle and boat engines, but between 1912 and 1928 they built a range of 276cc, 282cc, 294cc and 346cc side-valve single-cylinder A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder.

Side-valve
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1950s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-cylinder Engine
A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder. This engine is often used for motorcycles, motor scooters, go-karts, all-terrain vehicles, radio-controlled vehicles, portable tools and garden machinery (such as lawnmowers, cultivators, and string trimmers). Single-cylinder engines are made both as 4-strokes and 2-strokes. Characteristics Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Drawbacks of single-cylinder engines include a more pulsating power delivery through each cycle and higher levels of vibration. The uneven power delivery means that often a single-cylinder engine requires a heavier flywheel than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kevin Ash
Kevin Ash (10 December 1959 – 22 January 2013) was a British motorcycle journalist and author, who contributed to ''The Daily Telegraph'' and to ''Motor Cycle News''. Covering technical as well as topical issues, Ash was described as "one of the key figures of the British motorcycle scene", "one of the world's leading motorcycle journalists", and "the doyen of motorcycle correspondents." Personal life Ash was born in Ilford, a town in north-east London, part of Greater London administrative area. He attended Ipswich School, then studied engineering at Imperial College. In 1990, he married Caroline Quanjer, of the Netherlands, with whom he had three daughters: Laurien, Kirsten and Ingrid, who were 20, 18 and 10 at the time of his death. Career Before becoming a journalist, Ash was a motorcycle courier. He also participated in sidecar racing. In 1991, he was a founding contributor at the magazine ''Fast Bikes''. He then joined ''Motor Cycle News'' (''MCN'') as a road teste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
