Understanding Camshaft Specifications
Diagram: © Copyright Schrick
Explanations of the listed technical data
The opening angle and timing are minus the ramps indicated. The timings are given in EÖ (inlet opens in crankshaft degrees before TDC), ES (Inlet closes in ° after UT), AO (outlet opens in ° CA before BDC) and AS (Exhaust closes in ° CA after TDC). The spread is measured in °KW and describes the angular distance between outlet and ???. Inlet center of the gas exchange TDC (top Dead center). All valve lift values are excluding the valve clearance specified, that the actual Valve lift is smaller by the valve clearance. Since hydraulic cams have no clearance, match the strokes indicated to the actual Elevation values.
