EngineCR is a internal combustion engine compression ratio calculator. Automotive machine shops and engine builders can benefit from the use of EngineCR. EngineCR accurately calculates the static compression ratio of an engine. Calculations are based on the engine's bore, stroke, cylinder head chamber volume, piston design, deck clearance, and head gasket properties. Other features include a database utility to store and retrieve various engine specifications and a reports utility to generate and print compression and DB reports.
