A metered induction two cycle engine is presented. In accordance with the metered induction two cycle engine, an aspirating cylinder (or pulsing air-charger) is connected to a combustion cylinder by a voluminous transport duct having a valve disposed therein. The valve permits flow from the aspirating cylinder and duct to the combustion cylinder and prohibits flow in the opposite direction. The duct acts as an extension of the clearance volume of the aspirating cylinder. The valve is actuated when the pressure in the duct exceeds the pressure in the combustion cylinder. Further, the aspirating cylinder leads the combustion cylinder by a fixed amount to provide a disciplined flow of mixture (i.e., air and fuel) into the combustion cylinder.
