Abstract
A system and a method of facilitating fuel vaporization in a directly injected internal combustion engine are provided. As one example, vaporization may be improved by coordinating the timing of the directly injected fuel with intake valve opening while also utilizing negative valve overlap between the intake and exhaust valves to generate reduced pressures within the cylinder.
