Abstract
An internal combustion engine ( ) has an intake system ( ) that includes a turbocharger ( ). An engine control ( ) processes data for controlling the opening of the exhaust valves ( ) and for controlling fueling of the engine in relation to the engine operating cycle. In response to initiation of engine acceleration, the control increasingly retards exhaust valve opening in relation to the engine operating cycle to cause the turbocharger to increase pressure in the intake manifold ( ) and increases engine fueling in relation to the increased pressure in the intake manifold.
