Abstract: An improved multi-stroke DIG or diesel engine and method includes a cylinder formed within an engine cylinder block, a piston is movably disposed within the cylinder, and a combustion chamber is formed in a space between the piston and a cylinder head. An injector is disposed within the engine cylinder head for supplying fuel into the cylinder. An intake valve is disposed within an intake opening formed in the engine and an exhaust valve is disposed within an exhaust opening formed in the engine. An actuator is connected to the piston, wherein movement of the piston causes the actuator to open the exhaust valve a first predetermined amount at a beginning of the compression stroke of the piston to vent air through an exhaust channel formed in the engine and to close the exhaust valve after a predetermined period of time within the compression stroke of the piston.
