WebStatic Compression Ratio (SCR) is the ratio most commonly referred to. It is derived from the sweep volume of the cylinder using the full crank stroke (BDC to TDC). Dynamic Compression Ratio, on the other hand, uses the position of the piston at intake valve closing rather than BDC of the crank stroke to determine the sweep volume of the cylinder. Web1.

WebDec 9, 2011 · For example, a commom 208/218-112 looks like this: 208 + 218 = 426 / 4 = 106.5. That's 5.5 degrees less than your lobe separation, so you have 11 degrees of non-overlap. Try again, with a 236/242-110: 236 + 242 = 478 / 4 = 119.5. That's 9.5 degrees more than the lobe separation, so it has 19 degrees of overlap.
