Serpentine belt (foreground) and dual vee belt (background) on a bus engine Belt tensioner providing pressure against the back of a serpentine belt in an automobile engine. A serpentine belt (or drive belt [1]) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air ...
The Armstrong was a British 4-wheeled cyclecar made in 1913 by the Armstrong Motor Company of Birmingham. The car was available with a choice of air- or water-cooled, two-cylinder 8 hp engines made by Precision. The cheaper air-cooled version had belt drive to the rear axle, but the dearer water-cooled model had shaft drive. [2]
The six-cylinder 3,435 cc engine had hemi-spherical combustion chambers and could have optional twin Stromberg carburettors(£25 extra) [6] which increased the output from 125 to 150 bhp (93 to 112 kW) giving a top speed in excess of 100 mph (161 km/h). The front suspension was independent coil springs with a rigid axle and leaf springs at the ...
The Armstrong Siddeley Sapphire is a British turbojet engine that was produced by Armstrong Siddeley in the 1950s. It was the ultimate development of work that had started as the Metrovick F.2 in 1940, evolving into an advanced axial flow design with an annular combustion chamber that developed over 11,000 lbf (49 kN).
The first Armstrong Whitworth car was the 28/36 of 1906 with a water-cooled, four-cylinder side-valve engine of 4.5 litres which unusually had "oversquare" dimensions of 120 mm (4.7 in) bore and 100 mm (3.9 in) stroke. Drive was via a four-speed gearbox and shaft to the rear wheels.
Belt replacement is an obvious solution, and eventually the mandatory one (because no belt lasts forever). Often, though, before the replacement option is executed, retensioning (via pulley centerline adjustment) or dressing (with any of various coatings) may be successful to extend the belt's lifespan and postpone replacement.
The Armstrong Siddeley Viper is a British turbojet engine developed and produced by Armstrong Siddeley and then by its successor companies Bristol Siddeley and Rolls-Royce Limited. It entered service in 1953 and remained in use with the Royal Air Force , powering its Dominie T1 navigation training aircraft until January 2011.
The 1966 Pontiac OHC Six engine was the first US mass-produced vehicle to use a timing belt, [21] [22] while the 1966 Fiat Twin Cam engine was the first mass-produced engine to use a timing belt with twin camshafts. Carmakers began to adopt timing belts in the 1970s and compared to timing chains are less expensive, smaller, lighter, quieter ...
