The "Offy" engine was derived from this Miller marine engine An Offenhauser sprint "midget" racer. The Offenhauser engine, familiarly known as the "Offy", was an overhead cam monoblock 4-stroke internal combustion engine developed by Fred Offenhauser and Harry Arminius Miller. [4] Originally, it was sold as a marine engine.
The engine, later known as the "Big Six", was a 336 cu in (5.5 L) DOHC 2 valve-per-cylinder inline six that was fed by a centrifugal supercharger. It was manufactured by Offenhauser with final assembly by Sparks own people. It set fastest qualifying lap at Indianapolis in 1937, but retired due to supercharger problems. [2]: 71, 72
The flow in manifolds is extensively encountered in many industrial processes when it is necessary to distribute a large fluid stream into several parallel streams, or to collect them into one discharge stream, such as in fuel cells, heat exchangers, radial flow reactors, hydronics, fire protection, and irrigation. Manifolds can usually be ...
Carburetors used as intake runners A cutaway view of the intake of the original Fordson tractor (including the intake manifold, vaporizer, carburetor, and fuel lines). An inlet manifold or intake manifold (in American English) is the part of an internal combustion engine that supplies the fuel/air mixture to the cylinders. [1]
Typically though, a multi-point injected engine has one fuel injector per cylinder, an electric fuel pump, a fuel distributor, an airflow sensor, [5] and, in modern engines, an engine control unit. [6] The temperatures near the intake valve(s) are rather high, the intake stroke causes intake air swirl, and there is much time for the air-fuel ...
As of 2016, the third generation President of the company is Fred C. "Tay" Offenhauser, grand nephew of founder Fred C. Offenhauser. [1] [3] [2] After working with his uncle Fred H. Offenhauser in the 1930s and 1940s, Fred C. served in the US Navy during World War II, and returned home to found his speed parts business. The company is unrelated ...
The slanted cylinder block also provides space in the vehicle's engine bay for intake and exhaust manifolds with runners of longer and more nearly equal length compared to the rake- or log-style manifolds typical of other inline engines. The No. 1 and No. 6 intake runners are of approximately equal length, the No. 2 and No. 5 equal but shorter ...
The 301.6-cubic-inch (4.9 L) GMC inline six was produced from 1952 to 1960, when it was replaced by the V6. It has a square bore/stroke ratio of 4 by 4 inches (101.6 mm × 101.6 mm). This is the largest raised-deck engine. It was originally designed for the GMC military M135 and M211.
