Abstract
In an internal combustion engine comprising a gas recirculation passage connecting an exhaust manifold to an intake manifold, a compression release valve, and at least one gas pulse created during a first event, a method for retarding the engine comprising the steps of opening the compression release valve, releasing at least one gas pulse into the gas recirculation passage after a first event, redirecting the at least one gas pulse into the intake manifold, and using the at least one gas pulse to increase air charge in a cylinder.
