Abstract
A six-stroke engine system including an engine with a combustion chamber including an exhaust valve that expels exhaust gasses during an exhaust stroke, and a blowdown exhaust valve that expels blowdown exhaust gasses during recompression. An intake line directs air into the combustion chamber, and an exhaust line directs exhaust gasses from combustion chamber. A blowdown exhaust line directs blowdown exhaust gasses out of the combustion chamber and into the intake line. The blowdown exhaust gasses are expelled through the blowdown exhaust valve during recompression, and exhaust gasses are expelled through the exhaust valve during the exhaust stroke.
