Valve timing - Angles
The angle values are determined by turning the driving shaft
clockwise.
S = Piston at top dead centre
I = Piston at bottom dead centre
a = Intake valve open
β = Intake valve closed
γ = Exhaust valve open
δ = Exhaust valve closed
Timing angles for operating purposes
(valve clearance = 0.25 mm)
a = 16° before S
β = 36° after I
γ = 36° before I
δ = 16° after S
Timing angles for checking puposes
(valve clearance = 2 mm)
a = 21° after S
β = closes in I
γ = 2° after I
δ = 20° before S
