Abstract:
Cross-port air flow that improves engine fuel economy and reduces pumping losses during part-throttle operation can be implemented in various types of internal combustion engine systems using ports that interconnect the intake ports of different cylinders, thus allowing different cylinders to share combustion air. Cross-port air flow is commenced during part-throttle engine operation to disrupt the primary combustion air flow from each throttle to its associated cylinder, which reduces charge density and engine power. The engine compensates for the reduced power by incrementally opening the throttles, thus increasing the primary combustion air flow, reducing pumping losses and improving fuel economy.

Claim (Index 1):
A method of operating an internal combustion engine system, wherein the internal combustion engine system comprises:\n a plurality of cylinder assemblies comprising a first cylinder assembly and a second cylinder assembly;\n the first cylinder assembly comprising a first throttle operationally affixed to control combustion air flow into a first cylinder through a first intake port; \n the second cylinder assembly comprising a second throttle operationally affixed to control combustion air flow into a second cylinder through a second intake port; \n an intake-interconnecting port system comprising:\n a first interconnecting port connecting the first intake port downstream of the first throttle to the second intake port downstream of the second throttle; and \n a first valve within the first interconnecting port; \n the method comprising:\n detecting part-throttle operation of the engine system; \n if the first valve is closed, opening the first valve to permit combustion air flow from the second intake port to the first intake port through the first interconnecting port; \n adjusting the first throttle to reduce cylinder vacuum and reduce intake pumping work of the first cylinder assembly.
