Twenty-nine 4-6-2+2-6-4 Garratts, constructed between 1936 and 1941 by Société Franco-Belge in Northern France, operated until the Algerian independence war caused their withdrawal in 1951. This class, designated 231-132BT, was streamlined and featured Cossart motion gear, mechanical stokers and 1.8 m (5 ft 11 in) driving wheels, the largest ...
[1] [2] It is composed mostly of tiny fragments of the calcite shells or skeletons of plankton, such as foraminifera or coccolithophores. [1] These fragments mostly take the form of calcite plates ranging from 0.5 to 4 microns in size, though about 10% to 25% of a typical chalk is composed of fragments that are 10 to 100 microns in size.
The introduction of the 4-6-2 design in 1901 has been described as "a veritable milestone in locomotive progress". [3] On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...
The M4+2 engine, also known as the double-piston internal combustion engine, is a type of internal combustion engine invented by Polish patent holder Piotr Mężyk. [1] The M4+2 engine took its name from a combination of two-stroke engines and four-stroke engines. The two-stroke combustion engine is characterized by a simple construction and ...
The name "Challenger" was given to steam locomotives with a 4-6-6-4 wheel arrangement: four wheels in the leading pilot truck to guide the locomotive into curves, two sets of six driving wheels, and four trailing wheels to support the rear of the engine and its massive firebox. Each set of driving wheels is driven by two steam cylinders.
The Lionel Corporation used the 2-6-4 wheel arrangement in many of its model steam locomotives, including the 2037 used in the infamous pastel-coloured Girls' Train. [9] Their 2-6-4 model was based on the Pennsylvania Railroad’s K4 class pacific, even though this was a 4-6-2 rather than a 2-6-4. [10]
By 1876, Otto and Langen succeeded in creating the first internal combustion engine that compressed the fuel mixture prior to combustion for far higher efficiency than any engine created to this time. Daimler and Maybach left their employ at Otto and Cie and developed the first high-speed Otto engine in 1883.
85–89 kg (187–196 lb) [4] The Cosworth-Opel KF engine is a production-based, high-revving, prototype, four-stroke , 2.5-liter, naturally aspirated , V-6 racing engine , originally designed, developed and produced by Opel , in collaboration with Cosworth , for the DTM and later ITC , between 1993 and 1996 .
