An overhead valve engine, abbreviated (OHV) and 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 (or "sidevalve") engines , where the valves were located below the combustion chamber in the engine block .
Episode 1 features the surrender of Wernher von Braun to the Americans; at that time, he had a badly fractured arm, which was not mentioned in the series. In Episode 2 the narrator states twice that the R-7 rocket has 32 engines. This is not entirely correct. The R-7 and its successors have four side boosters and a core booster. Each side ...
The 1960s E series was an all-new design from newly acquired Aichi Kokuki, and integrated Nissan's improvements to the BMC B-Series engine design of the 1950s (Nissan was a licensee of Austin Motor Company technology), mainly comprising changing the camshaft from the left side to the right side so removing the intrusion of the pushrods from the ...
Pushrods are long, slender metal rods that are used in overhead valve engines to transfer motion from the camshaft (located in the engine block) to the valves (located in the cylinder head). The bottom end of a pushrod is mated to a lifter, upon which the camshaft makes contact. The camshaft lobe moves the lifter upwards, which moves the pushrod.
The Chevrolet Inline-4 engine was one of Chevrolet's first automobile engines, designed by Arthur Mason and introduced in 1913. Chevrolet founder Billy Durant, who previously had owned Buick which had pioneered the overhead valve engine, used the same basic engine design for Chevrolet: exposed pushrods and rocker arms which actuated valves in the detachable crossflow cylinder head.
The Toyota K series is an inline-four engine that was produced from 1966 through 2007. It is a two-valve pushrod engine design. It was originally built from the Toyota Kamigo plant in Toyota City factory in Japan. All K series are non-crossflow engines – the inlet and exhaust manifolds are on the same side.
The 7-16 DIN connector or 7/16 (seven and sixteen millimeter DIN) is a 50 Ω threaded RF connector used to join coaxial cables. It was designed to reduce passive intermodulation from multiple transmitters. It is among the most widely used high power RF connectors in cellular network antenna systems. Originally popular in Europe, it has gained ...
