The Harrison was an American automobile built in Grand Rapids, Michigan originally by the Harrison Wagon Company from 1905 through 1906. The company was renamed to the Harrison Motor Car Company in 1907 before going defunct the same year.
The Harrison grew to be a large vehicle, eventually having a wheelbase of 10 ft (3.0 m). The 1906 and 1907 models featured a self-starting system which introduced acetylene into the proper cylinder for starting 'on the spark'. The cars came with a four-cylinder engine of 6.3L in capacity, with overhead valves. Pushrods for the exhaust valves had a ring-shaped section so they could straddle the exhaust piping.
The sleeve valve is a type of valve mechanism for piston engines, distinct from the usual poppet valve. Sleeve valve engines saw use in a number of pre–World War II luxury cars and in the United States in the Willys-Knight car and light truck. They subsequently fell from use due to advances in poppet-valve technology, including sodium cooling, and the Knight system double sleeve engine's tendency to burn a lot of lubricating oil or to seize due to lack of it. The Scottish Argyll company used its own, much simpler and more efficient, single sleeve system (Burt-McCollum) in its cars, a system which, after extensive development, saw substantial use in British aircraft engines of the 1940s, such as the Napier Sabre, Bristol Hercules, Centaurus, and the promising but never mass-produced Rolls-Royce Crecy, only to be supplanted by the jet engines.
A four-strokeengine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed:
A hemispherical combustion chamber is a type of combustion chamber in a reciprocating internal combustion engine with a domed cylinder head notionally in the approximate shape of a hemisphere. An engine featuring this type of hemispherical chamber is known as a hemi engine.
A crossflow cylinder head is a cylinder head that features the intake and exhaust ports on opposite sides. The gases can be thought to flow across the head. This is in contrast to reverse-flow cylinder head designs that have the ports on the same side.
The Alcyon was a French bicycle, automobile and motorcycle manufacturer between 1903 and 1954.
S.P.A. was an Italian automobile, military vehicle and aero-engine manufacturer founded in Turin by Matteo Ceirano and Michele Ansaldi. It was active between 1906 and 1926. In 1908, it merged with Fabbrica Ligure Automobili Genova (FLAG) and the new company, Società Ligure Piemontese Automobili, was headquartered in Genoa while manufacturing in Turin.
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.
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
Itala was a car manufacturer based in Turin, Italy, from 1904 to 1934, started by Matteo Ceirano and five partners in 1903.
The Knight engine is an internal combustion engine, designed by American Charles Yale Knight (1868-1940), that uses sleeve valves instead of the more common poppet valve construction.
The intake/inlet over exhaust, or "IOE" engine, known in the US as F-head, is a four-stroke internal combustion engine whose valvetrain comprises OHV inlet valves within the cylinder head and exhaust side-valves within the engine block.
Buchet was a French motorcycle and automobile manufacturer between 1899 and 1930.
The uniflow type of steam engine uses steam that flows in one direction only in each half of the cylinder. Thermal efficiency is increased by having a temperature gradient along the cylinder. Steam always enters at the hot ends of the cylinder and exhausts through ports at the cooler centre. By this means, the relative heating and cooling of the cylinder walls is reduced.
The Rolls-Royce 15 hp was one of four cars to be produced as a result of an agreement of 23 December 1904 between Charles Rolls and Henry Royce. Badged as a Rolls-Royce, the 15 hp was produced by Royce's company, Royce Ltd., at its factory in Cooke Street, Hulme, Manchester. It was sold exclusively by Rolls' motor dealership, C.S.Rolls & Co., at a price of GBP500. The 15 hp was exhibited at the Paris Salon in December 1904, along with the 10 hp, 20 hp and engine for the 30 hp models, but as the new three-cylinder engine was not ready the chassis was incomplete.
Quadrant was one of the earliest British motorcycle manufacturers, established in Birmingham in 1901. Famous for their big singles, Quadrant pioneered many innovations that proved important for motorcycle development but struggled after the First World War and the company was wound up in 1928.
The South African Railways Class Experimental 1 4-6-2 of 1907 was a steam locomotive from the pre-Union era in the Cape of Good Hope.
The Austin 25-30 is a motor car. It was the first automobile produced by newly established British car manufacturer Austin.
Gobron-Brillié was an early French automobile manufactured from 1898 to 1930. The original company, Societé des Moteurs Gobron-Brillié, was founded by the French engineer, Eugène Brillié, and industrialist, Gustave Gobron, at 13, quai de Boulogne, Boulogne-sur-Seine, near Paris, in 1898.
The South West African 2-8-0T of 1907 was a steam locomotive from the German South West Africa era.
An internal combustion engine is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons, turbine blades, a rotor, or a nozzle. This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to.
