The Super Turbine 300 (abbreviated ST-300) [1] [2] was a two-speed automatic transmission built by General Motors. It was used in various Buick , Oldsmobile , and Pontiac models from 1964-1969. It was the same transmission marketed under different brand names by each division including ST-300 by Buick, Jetaway by Olds and simply Automatic by ...
The 6HP is the first transmission to use this 6-speed gearset concept. The last 6HP automatic transmission was produced by the Saarbrücken plant in March 2014 after 7,050,232 units were produced. [3] [4] The ZF plant in Shanghai continued to produce the 6HP for the Chinese market. [3]
In 1980 the Federal Trade Commission filed a complaint which included the diesel engine issues and the transmission troubles, as well as camshaft issues with gasoline V8s. [2] General Motors kept marketing the diesel to the fullest, with 19 of the 23 Oldsmobile models in 1981 being available with the 5.7 diesel. [3]
Most STD transmissions have a first gear of 3.75 to 4.10:1 for smaller-displacement engines; these so-called 4-cylinder T-5s are rated up to 240 lb⋅ft (330 N⋅m) of input torque. [ 4 ] WC transmissions initially carried the same maximum input torque rating of 265 lb⋅ft (359 N⋅m) until hardened first gears were introduced in approximately ...
Low speed diesel engines like the MAN S80ME-C7 have achieved an overall energy conversion efficiency of 54.4%, which is the highest conversion of fuel into power by any single-cycle internal or external combustion engine. [9] [10] [11] Engines in large diesel trucks, buses, and newer diesel cars can achieve peak efficiencies around 45%. [12]
Diesel engines are used in aircraft, automobiles, power generation, diesel–electric locomotives, and both surface ships and submarines. The Diesel cycle is assumed to have constant pressure during the initial part of the combustion phase (to in the diagram, below). This is an idealized mathematical model: real physical diesels do have an ...
Similarly the "Low Temperature Flow Test" (ASTM D4539 [1]) indicates the winter performance of diesel with improver additives. Note that both the CFPP and LTFT temperature is some degrees above the pour point temperature at which diesel fuel loses its fluid character and that pumps would stop operating.
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
