Abstract
A tuned induction control system for an engine at or near full load having a piston that is reciprocally disposed in a cylinder includes a first module that actuates an intake valve associated with the cylinder and a second module that determines a second intake valve open timing based on an intake air temperature, pressure and an engine speed. The first module actuates the intake valve during a first intake event and actuates the intake valve during a second intake event that is subsequent to the first intake event. The first and second intake events occur during a common intake stroke of the piston and the intake valve is opened at the second intake valve open timing during the second intake event.
