When these engines were designed, technology was less advanced, and manufacturers made all parts very large. A typical 6-horsepower (4.5 kW) engine weighs approximately 1,000 pounds (450 kilograms). Typically, the material for all significant engine parts was cast iron. Small functional pieces were made of steel and machined to tolerance. [1]
A crosshead as part of a reciprocating piston and slider-crank linkage mechanism. Cylindrical trunk guide Hudswell Clarke Nunlow; crosshead and two slide bars. In mechanical engineering, a crosshead [1] is a mechanical joint used as part of the slider-crank linkages of long stroke reciprocating engines (either internal combustion or steam) and reciprocating compressors [2] to eliminate ...

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 12- to 17-year-old age group was dominant. [27] YouTube's pre-eminence in the online market was substantial. According to the website Hitwise.com, YouTube commanded up to 64% of the UK online video market. [28] YouTube entered into a marketing and advertising partnership with NBC in June 2006. [29]
The Monosoupape (French for single-valve), was a rotary engine design first introduced in 1913 by Gnome Engine Company (renamed Gnome et Rhône in 1915). It used a clever arrangement of internal transfer ports and a single pushrod-operated exhaust valve to replace the many moving parts found on more conventional rotary engines, and made the Monosoupape engines some of the most reliable of the era.
An oscillating cylinder engine cannot be reversed by means of the valve linkage (as in a normal fixed cylinder) because there is none. Reversing of the engine can be achieved by reversing the steam connections between inlet and exhaust or, in the case of small engines, by shifting the trunnion pivot point so that the port in the cylinder lines up with a different pair of ports in the port face.
Russell & Co reportedly started building steam traction engines after their 1878 incorporation, and by 1880, they employed 425 people on a seven acre site, with their own railroad sidetrack. [3] By 1884, they had become one of the largest producers of steam traction engines, plus building industrial, railroad and agricultural equipment. [2]
