Abstract
A gas recirculation system is disclosed for improving engine braking in an internal combustion engine having an intake valve, an exhaust valve, and a cylinder. The system includes an exhaust manifold operatively connected to the cylinder through the exhaust valve; an intake manifold operatively connected to the cylinder through the intake valve; and a gas recirculation passage adapted to recirculate gas from the exhaust manifold to the intake manifold during an engine braking event.
