What is cylinder gas re-expansion and why is it a problem?
What will be an ideal response?
Gas trapped in the compressor clearance space is expanded at the beginning of the suction stroke. This causes inefficiency because new suction gas cannot enter the cylinder until the trapped gas is at a pressure below the suction pressure.
