Czech term or phrase: stříhání ventilů (neboli ventily ve střihu)
All technicians know what it means (a moment/camshaft position, when the exhaust valve is just closing and intake valve is just opening), but I would like to know the correct English term for it.
I suppose it has nothing to do with "shearing".

Valve overlap:
A certain period in which both the intake and exhaust valve are partially open. The intake is starting to open while the exhaust is not yet closed. It is usually expressed in degrees of crankshaft rotation and determined by the valve timing, valve overlap is necessary for the efficient flow of gases in and out of the combustion chamber

Valve Overlap: This is the number of degrees where the exhaust valve is still open - on it's closing ramp . . . and the intake valve is starting to open on it's opening ramp.
