All Sturmey-Archer gear hubs use epicyclic (planetary) geartrains of varying complexity. The AW is the simplest, using one set of planetary gears with four planets. The AM uses three compound planets with differently sized cogs machined from a common shaft to engage the gear ring and sun gear separately, while the close-ratio three-speeds, and hubs with four or more speeds, use multiple ...
Three-speed bicycle. The three-speed bicycle is a bicycle that uses internal hub gears at the rear wheel hub to provide three gear ratios. Three-speed hubs have been in use since the early 1900s. Though they are heavier than comparable derailleur systems, internal-gear hub systems generally last longer and require less maintenance.
A backfire or afterburn is combustion or an explosion produced by a running internal combustion engine that occurs in the exhaust system, rather than inside the combustion chamber. It is also sometimes referred to as an afterfire, especially in cases where the word backfire is used to mean a fuel burn that occurs while an intake valve is open ...
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
The supercharger he designed was used for one of NSU's 50 cm 3 one-cylinder two-stroke engines. The engine produced a power output of 13.5 PS (10 kW) at 12,000 rpm. [9] In 1954, NSU agreed to develop a rotary internal combustion engine with Felix Wankel, based upon Wankel's supercharger design for their motorcycle engines.
In January 1904 they were working on a tri-car powered by a 3.5HP water-cooled four-stroke engine, with 2-speed gearbox and novel clutch system. [5] In 1904 Ormonde merged with the engine maker Kelecombe, and when this company failed Taylor Gue bought the assets, and in 1905 built their first motorcycle, the Veloce .

In spite of the huge success of the 269 cc two-stroke, the four-stroke engine had not completely been shelved, as in October 1914, J.H Motors of Oldham announced [3] two motorcycles, the No.1 fitted with a 2.75 hp Villiers four-stroke engine of 349 cc (74.5 x 80 mm bore and stroke), and a 2.5 hp two-stroke model using the Villiers 269 cc engine ...
