Charles Foster Johnson's animated GIF image comparing a memo purportedly typewritten in 1973 with a proportional-spaced document made in Microsoft Word with default settings in 2004 The Killian documents controversy (also referred to as Memogate or Rathergate [1] [2] ) involved six documents containing allegations about President George W. Bush ...
The NCR Century 100 was NCR's first all integrated circuit computer built in 1968. [1] All logic gates were created by wire-wrapping NAND gates together to form flip-flops and other complex circuits. The console of the system had only 18 lights and switches and allowed entry of a boot routine, or changes to loaded programs or data in memory.
Four-stroking is a condition of two-stroke engines where combustion occurs every four strokes or more, rather than every two. Though normal in some instances at idle , extremely high engine speeds, and when letting off the throttle, such firing is uneven, noisy and may, in cases of malfunction, damage the engine if allowed to continue unabated.
The power produced by the Otto cycle is an energy developed per unit of time. The Otto engines are called four-stroke engines. The intake stroke and compression stroke require one rotation of the engine crankshaft. The power stroke and exhaust stroke require another rotation. For two rotations there is one work generating stroke..
The two-stroke combustion engine is characterized by a simple construction and system of air load change, as well as a bigger index of power output. Unfortunately, its filling ratio is worse than in a four-stroke engine. The ecological index of a two-stroke engine is also unfavorable. The system of valves of the four-stroke engine is its ...
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.

Design four stroke Straight-three engine with firing order 1-3-2. A crankshaft angle of 120 degrees is often used on inline three cylinder engines, since this results in an evenly spaced firing interval in the case of 2 stroke/2 cycle engines. however a 120 degree crnkshaft gives unequal firing intervals for 4 stroke/4 cycle enigines and for these a 180 degree crankshft is sometimes used ...
