Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve. [2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system.
Chesapeake and Ohio No. 490 is the sole survivor of the L-1 class 4-6-4 "Hudson" type steam locomotives.It was built by ALCO's Richmond works in 1926 as an F-19 class 4-6-2 "Pacific" type to be used to pull the Chesapeake and Ohio's secondary passenger trains.
In both types of engines there are one or more cylinders (grey and green), and for each cylinder there is a spark plug (darker-grey, gasoline engines only), a piston (yellow), and a crankpin (purple). A single sweep of the cylinder by the piston in an upward or downward motion is known as a stroke.
Judy while on loan to the Bristol Harbour Railway in 2015. Works number 2572, built 1937. Bagnall designed a locomotive that was only 90 inches (2.3 m) high by dropping the cab floor down between the main frames. 16 ft 6 in (5.03 m) long over headstocks and 7 ft 5 in (2.26 m) wide, Judy's 33 in (840 mm) wheels were just 5 feet (1,500 mm) apart, allowing her to negotiate the sharp curve by Par ...
The first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.
Most politically charged item. Rest in peace, Adidas Sambas. Time of death: April 4, 2024 — coincidentally the same time former Britain’s then-Prime Minister Rishi Sunak donned a pair for a ...
Ray-traced image of a piston engine. There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, either already under pressure (e.g. steam engine), or heated inside the cylinder either by ignition of a fuel air mixture (internal combustion engine) or by contact with a hot heat exchanger in the cylinder (Stirling engine).
