Crank angle
The crank angle is a term used in reciprocating engine technology and describes the angle of the crankshaft in relation to the top dead center of the piston . It is specified in the non-SI unit of measurement, which can be used jointly with the SI system, in degrees crank angle (° CA) or in radians (rad). The symbol is . With a four-stroke engine , all work cycles are run through 720 ° CA, with a two-stroke engine it is 360 ° CA.
