The Dorman Association shows that from 1913 the JJ and JO engines were available in either 2-cylinder or 4-cylinder form, each with the same 110 mm bore and 140 mm stroke and with 8 bhp per cylinder. It is known that the 4-cylinder Dorman engine was fitted into the Pagefield trucks made by Walker Brothers of Wigan in 1913 to a War Department ...
The engine was a single-cylinder unit that displaced 6.1 dm 3, and was rated 3 PS (2,206 W) at 180/min, with a fuel consumption of 0.95 m 3 /PSh (1.29 m 3 /kWh). [ 17 ] : p43-44 Wilhelm Maybach later improved the engine by changing the connecting rod and piston design from trunk to crosshead , so it could be put into series production.
The driving wheel diameter was reduced to 5 ft 3 + 1 ⁄ 2 in (1.613 m) from the 1252's 5 ft 6 + 1 ⁄ 2 in (1.689 m) – the 6 class had used 5 ft 3 in (1.600 m) drivers. The wheelbase was the same as the previous two classes, as was the cylinder bore and stroke at 17 in × 24 in (432 mm × 610 mm).
By 1914 the entire Midland network was being operated by six basic engine designs: a Class 1 0-6-0 tank engine for light freight and shunting, Class 1 0-4-4T tank engine for light passenger work, Class 2 4-4-0 engine for general passenger work, Class 3 0-6-0 engines in tank and tender variants for mixed traffic and freight, and Class 4 4-4-0 ...
No 1042 (Deeley-built) with a Bradford to London express, between 1908–1910. These were developed from a series of five locomotives (2631–2635) introduced in 1902 by Samuel Waite Johnson, which had a 3-cylinder compound arrangement on the Smith system, with one high-pressure cylinder inside the frames and two low-pressure cylinders outside, and used Smith's starting arrangement.
1816 – Robert Stirling invented his hot air Stirling engine, and what we now call a "regenerator". [5] [6] 1821 – Michael Faraday builds an electricity-powered motor. 1824 – Nicolas Léonard Sadi Carnot first publishes that the efficiency of a heat engine depends on the temperature difference between an engine and its environment.
One example was a 3.1 litre (186 cu in) unit producing 22 kW (30 hp) at 1,300 rpm. [5] Although termed the Y engine after its symmetric cylinder arrangement, it ran in an inverted Y position so that the plugs, mounted on the upper in-plane side of the two lower cylinders were less than 30° below the horizontal and less prone to oiling than one ...
Animation of the 1-2-4-5-3 firing order MAN B&W 5S50MC 1,865 litre marine diesel engine. Straight-five engines are typically shorter than straight-six engines, making them easier to fit transversely in an engine bay. [1] They are also smoother than straight-four engines, [1] and are narrower than V engines [2] and flat engines.
