On April 7, 1964, IBM announced the IBM System/360, to be available in six models. [3] [4] [5] The 360/40 was first delivered in April 1965.[6]The 360/30 and the 360/40 were the two largest revenue producing System/360 models, [7] accounting for over half of the units sold.
Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
Timing belts are typically located in front of the engine and are often behind a cover for protection against dust and debris. However a few engines since 2008 have used "wet timing belts", whereby the belt is lubricated by engine oil to reduce friction losses by 30% and thus reduce fuel consumption by 1%. [7]
For example, even though the IBM System/360 instruction set architecture was a 32-bit instruction set, the System/360 Model 30 and Model 40 had 8-bit data paths in the arithmetic logical unit, so that a 32-bit add required four cycles, one for each 8 bits of the operands, and, even though the Motorola 68000 series instruction set was a 32-bit ...
The EMD Model 40 was a two-axle diesel-electric switcher locomotive built by Electro-Motive Corporation (EMC), and its corporate successor, General Motors' Electro-Motive Division (EMD) between August 1940 and April 1943. Nicknamed "critters", eleven examples of this locomotive were built.
[1] [2] It served as BMW's base model four-cylinder engine and was produced alongside the higher performance BMW M42 DOHC four-cylinder engine from 1989 onwards. Compared with its M10 predecessor, the M40 uses a belt-driven camshaft, [3] and hydraulic tappets. Like the M10, the M40 uses an iron block and an aluminium head.
The A-40-4 introduced an increase in power to 40 hp (30 kW). The engine later inspired the A-50 and subsequent engines. [1] [2] [4] The A40 featured single ignition until the A-40-5 version, which introduced dual ignition. All engines in this family have a 5.2:1 compression ratio and were designed to run on fuel with a minimum octane rating of ...
The "Deluxe" name was first used starting in 1930 to specify an upscale trim starting with the Model 40-B and Model 45-B, then later the De Luxe Ford line was differentiated as a separate "marque within a marque" with separate styling and pricing through 1940. [3]
