The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine.It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion chamber.
When the boat has more than one rower, the rower closest to the stern of the boat is referred to as "stroke". This is the most important position in the boat, because the stroke rower sets the stroke rate and rhythm for the rest of the crew to follow. Stroke seat has to be a very calm and yet very competitive individual.
An engine is described as oversquare or short-stroke if its cylinders have a greater bore diameter than its stroke length, giving a bore/stroke ratio greater than 1:1. An oversquare engine allows for more and larger valves in the head of the cylinder, higher possible rpm by lowering maximum piston speed, and lower crank stress due to the lower ...
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: Intake: Also known as induction or suction. This stroke of ...
Stroke, a trace of ink in handwriting; Stroke, a line that makes up part or all of a letter in typeface anatomy; Stroke, one of the two basic methods of drawing a path in vector graphics; Bar (diacritic) or stroke, a line drawn across a grapheme. Slash (punctuation), the typographical character, is also known as a "stroke"
These results and the first mentioning of the term ischemic penumbra were published in 1977 in Stroke (1), and further substantiated by an editorial in 1981 (2). The first decade of research focused on physiologic profile of the penumbra tissue after stroke , mapping the cerebral blood flow, and quantifying oxygen and glucose consumption to ...
[249] [250] The word stroke was used as a synonym for apoplectic seizure as early as 1599, [251] and is a fairly literal translation of the Greek term. The term apoplectic stroke is an archaic, nonspecific term, for a cerebrovascular accident accompanied by haemorrhage or haemorrhagic stroke. [252]
In handwriting research, the concept of stroke is used in various ways. In engineering and computer science, there is a tendency to use the term stroke for a single connected component of ink (in Off-line handwriting recognition) or a complete pen-down trace (in on-line handwriting recognition). Thus, such stroke may be a complete character or ...
