Abstract
A gasoline direct injection engine is provided with a bypass air supply line. The bypass line is selectively opened to allow additional flow of air into the engine chamber during a transition phase. Air normally flows through a main air supply line through a plenum. However, during a transition from a low air volume early injection phase to a relatively high air volume late injection phase the valve is opened to provide additional flow through the bypass. In this way, the air can be more quickly delivered to the engine chamber.
