The cam is connected by a 2-1 ratio sprocket or gears, so it only turns once to the crank’s two turns (Two crank degrees equal one cam degree).

What is Valve Timing & How It Affects Engine …

2019-3-12 · The valve overlap: In the exhaust stroke, the piston again moves upwards; pushing the exhaust gas out through the open exhaust valve. The exhaust valve opens before the piston reaches BDC in its power stroke. As the exhaust valve opens just before BDC, it causes some of the pressurized exhaust gases to escape even before the piston starts it’s upwards stroke.

2015-4-6 · The reason for this is simply that grinding the original camshaft will not increase the valve lift (speed of lift and opening duration can be reground) and can, in some cases, cause serious engine damage, as the grinding process can remove any surface hardness the manufacturer saw fit to include in its camshaft specification.

COMP Cams Valve Timing Tutorial

COMP Cams Valve Timing Tutorial

Each "stroke" lasts one half crankshaft revolution or 180 crankshaft degrees. Since the camshaft turns at half of the speed of the crank, the power stroke only sees one fourth of a turn of the cam, or 90 camshaft degrees. As we move closer to the bottom of the cylinder, a little before the piston reaches the bottom, the exhaust valve begins to ...

 · Not sure I follow. Grinding the pins at 12 and 6 o'clock add/remove stroke; I assume 12 o'clock is pointing back towards TDC? So grinding at 3 or 9 o'clock would change the TDC position with respect to crank angle, and could upset the balance of the engine (as well as buggering up valve timing).
