This was done by Alco to disassociate the 250 from the troublesome 244 engine. The 250 was produced for a short time from 1955 into 1956. It was also used as a standard to rebuild older 244 engines at Schenectady. In 1949, in the midst of continued failures of 244 engines, ALCO engineers began work on a clean-sheet diesel engine. [12]
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

The Turbo-Thrift 250 (also known as the High Torque 250 in trucks) version was introduced in 1966, with the same 3.875 in (98.4 mm) bore as the 230 and a longer 3.53 in (90 mm) stroke for a larger 249.8 cu in (4.1 L; 4,093 cc) displacement. Between 1975 and 1984, an integrated cylinder head was produced (intake manifold and cylinder head were a ...
The revamp was divided into individual projects. The singles project, which consisted of the 250 cc B25 and a new 500 cc B50, was code-named P34. [28] The engine received some upgrades. Failures of the conrod was addressed by redesigning the conrod with a larger shoulder section. This required the crankshaft to be machined to clear the thicker ...
The engines in both the XR250R and XR250L are identical. In the United States the L has a 3 mm smaller header pipe and a different carburetor to satisfy emissions regulations, though both carburetors have a 30 mm bore. The engine has a four-valve head with splayed rocker arms to actuate the valves. Unusual for a single-cylinder engine, it has a ...
1994 would see the 604 revised into the 605, as well as the introduction of the 600 Flat Track model. 1996 brought the liquid-cooled 250 and 260 lines, as well as a Limited Edition 406 send-off model as ATK retired their open-class two-stroke offering. 1999 would see the introduction of the 50MX, an introductory motocross/pit bike model sold ...
V-8 engines were produced by the Daimler Company in displacements of 2.5 L (153 cu in) (1959-1968) and 4.5 L (275 cu in) (1959-1968). Designed for Daimler by Edward Turner, they were initially used in the SP250 sports car and the Majestic Major saloon respectively; ultimately, the 2.5 L was mostly used in the Daimler 2.5 V8 (later named V8-250) saloon made with Jaguar Mark 2 unit bodies from ...
