Reply to "106 Lobe Separation Angle"

The numbers are expressed in the terms in which you would use them, there's really never a need to convert one term in order to relate to the other.

However, to satisfy your question, 1° of camshaft rotation = 2° of crankshaft rotation. The camshaft turns at half the speed of the crankshaft. The camshaft only rotates once for each time the crankshaft rotates twice. The piston makes four strokes, twice up and twice down, during the time in which the camshaft makes one rotation.

One interesting mathematic aspect of the LSA:

(exhaust centerline degrees + intake centerline degrees) ÷ 2 = Lobe Separation Angle
