A system and method to control an engine wherein at least intake valve timing is retarded relative to a crankshaft position depending on engine operating conditions. According to the method, at least a portion of the fuel is injected during the intake valve open period with retarded valve timing. The method can reduce fuel consumption, reduce transient fuel requirements, improve engine performance, and reduce CO emissions, at least under some conditions.
