Abstract
A method of operating an engine in a delayed exhaust engine cycle may include opening an intake valve of the engine during a first stroke to form an intake stroke. The method may further include closing the intake valve and determining an engine operating temperature. The engine operating temperature may be compared to a predetermined temperature limit. A first fuel mass may be provided to the combustion chamber between an end portion of a second stroke and a beginning portion of a third stroke. The third stroke may form a first power stroke and the intake valve and an exhaust valve in communication with the combustion chamber may be closed during the second and third strokes. The exhaust valve may be maintained in a closed position during a fourth stroke when the engine operating temperature is less than the predetermined temperature limit.
