Abstract
A method for controlling combustion in a combustion chamber of a turbocharged engine is described. The method includes admitting to the combustion chamber prior to ignition a first amount of exhaust from an intake manifold of the engine, the first amount changing at a first rate in response to a changing engine load. The method also includes retaining in the combustion chamber prior to the ignition a second amount of exhaust from the combustion chamber, the second amount changing at a second rate, greater than the first rate, in response to the changing engine load.
