Compression Ratio (Total Swept Volume) a = Combustion Chamber Volume at TDC: b = Cylinder Displacement (cc) Formula: (a + b) / a: Example: (100.00 + 823.70 ) / 100.00 = 9.237: Rod Ratio: a = Rod Length: b = Stroke of Engine: Formula: a / b: Example: 6.0 / 3.5 = 1.714: Rod Length: a = Cylinder Block Length: b = Deck Clearance: c = Target Compression Height of Piston: d = Stroke of Engine ...
