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 16):
An internal combustion engine system comprising:\n a first cylinder assembly comprising:\n a first cylinder; \n a first intake valve system comprising:\n a first intake valve controlling admission of combustion air to the first cylinder from a first intake port; and \n a second intake valve controlling admission of combustion air to the first cylinder from a second intake port; \n \n a first induction system comprising a first throttle mechanism, the first throttle mechanism comprising:\n a first throttle plate operationally affixed to control combustion air flow into the first cylinder through the first intake port; and \n a second throttle plate operationally affixed to control combustion air flow into the first cylinder through the second intake port; \n \n a second cylinder assembly comprising:\n a second cylinder; \n a second intake valve system comprising:\n a third intake valve controlling admission of combustion air to the second cylinder from a third intake port; and \n a fourth intake valve controlling admission of combustion air to the second cylinder from a fourth intake port; \n \n a second induction system comprising a second throttle mechanism, the second throttle mechanism comprising:\n a third throttle plate operationally affixed to control combustion air flow into the second cylinder through the third intake port; and \n a fourth throttle plate operationally affixed to control combustion air flow into the second cylinder through the fourth intake port; and \n \n an air flow equalizing system comprising a first equalizing passage connecting the second intake port downstream of the second throttle plate to the third intake port downstream of the third throttle plate.
