Apollo (1910 Automobile)
The Apollo was a German automobile manufactured by Ruppe & Son of Apolda in Thuringia from 1910 to 1927; the company had previously offered a car called the Piccolo. The first Apollo was called the "Mobbel", and featured an air-cooled 624cc single-cylinder ioe engine. The company also offered air-cooled 1608 cc in-line fours and a 1575 cc V-4. Four separate cylinders inline powered the model "E" (1770cc). The model "B", designed by racing driver Karl Slevogt, had an ohv 960 cc four-cylinder engine. Another of the designer's fine creations had an ohv 2040 cc engine. Other Apollos had sv four-cylinder engines of up to 3440 cc; some post-1920 models featured wishbone suspension. The last cars produced by the company had ohv 1200 cc four-cylinder engines; some had sv 1551 Steudel four-cylinder power units instead.

Overhead Valve Engine
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 earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succe ...

Paul Jaray
Paul Jaray ( Hungarian: ''Járay Pál''; 11 March 1889 – 22 September 1974) was an engineer, designer, and a pioneer of automotive streamlining. Life Jaray, of Hungarian-Jewish descent, was born in Vienna. Jaray studied at ''Maschinenbauschule'' in Vienna and worked at the Prague Technical University as an assistant to Professor Rudolf Dörfl. Later he became the chief design engineer for the aircraft building firm Flugzeugbau Friedrichshafen, designing seaplanes. From 1914 Jaray worked at Luftschiffbau Zeppelin, located in the same town, concentrating on streamlining airships. Jaray designed the airship LZ 120 Bodensee on which airships such as the LZ 127 Graf Zeppelin, the LZ 129 Hindenburg and the LZ-130 were later based. Further experiments in LZ's wind tunnel led to his establishment of streamlining principles for car designs. In 1923 he moved permanently to Switzerland, opening an office in Brunnen. In 1927, Jaray founded the Stromlinien Karosserie Gesellschaft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Markranstädter Automobilfabrik
The Markranstädter Automobilfabrik is a former producer of automobiles from Markranstädt, Germany, which was active between 1909 and 1923. Hugo Ruppe founded the Markranstädter car factory in 1909, producing cars that were sold under the brand name ''MAF''. The first model was the Type D 4 from 1909 to 1913. Its air-cooled four-cylinder engine with 1192 cc provided 12 PS. The Type F 5 followed in 1913 with 1375 cc and 14 hp, and the G 6 with 1620 cc and 16 hp. Due to the outbreak of World War I in 1914 production was interrupted. After the war MAF produced the pre-war type F 5, and the 6 / 18 hp which replaced the G 6. MAF also built the type 8 / 25 hp, and the large 14 / 35 hp with a six-cylinder engine. In 1921 the factory was taken over by the Apollo-Werke AG, and in 1923 the last models were produced by MAF. Very few examples of the MAF remain today. A type F 5 / 14 PS of 1914 is in the Cité de l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Wishbone Suspension
A double wishbone suspension is an independent suspension design for automobiles using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff and more. Implementation The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped, L-shaped, or even a single bar linkage. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut. The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrangement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sidevalve
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] |

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber.
