Compression Ratio Calculator (Static and Dynamic)

WebCompression does not begin until the intake valve closes (IVC). Once IVC is reached, the air fuel mixture starts to compress. The ratio of the cylinder volume at IVC over the volume above the piston at TDC represents the dynamic compression ratio. The DCR is what the air fuel mixture actually “sees” and is what “counts”, not the static CR. WebA diesel engine with a compression ratio equal to 20 is modeled using air.
