Camshaft duration vs rpm
WebWhat is valve overlap and why is it important. Valve overlap is mostly a function of duration and lobe separation angle (LSA), and to some minor degree valve lift. If the LSA remains the same but you increase the duration, the amount of overlap will also increase. Overlap is the span (measured in crankshaft degrees) when the exhaust valve and ... WebApr 18, 2016 · Valve timing events can be tailored in several ways. Option one is duration can be added or subtracted. If duration is added to the lobe, the valve is opened and closed later. Conversely, removing duration delivers inverse results. The other method is advancing or retarding the camshaft. Advancing the cam lobe opens and closes the …
