ABSTRACT:
A method includes operating a first cylinder defined by an internal combustion engine in a combustion mode and operating selectively a second cylinder defined by the internal combustion engine in one of a combustion mode or a pumping mode. When the first cylinder is operating in the combustion mode, air is conveyed into the first cylinder from an intake manifold, the air is mixed with fuel and the mixture of the fuel and the air is combusted within the first cylinder. When the second cylinder is operating in the combustion mode, air is conveyed into the second cylinder from the intake manifold, the air is mixed with fuel and the mixture of the fuel and the air is combusted within the second cylinder. When the second cylinder is operating in the pumping mode, air is conveyed into the second cylinder from the intake manifold, the air is compressed without being mixed with fuel and without being combusted, and the compressed air is conveyed into the intake manifold from the second cylinder.
