Abstract: An engine system (20) is disclosed. The engine system may have a first bank (26) of cylinders (24), a second bank (28) of cylinders (24), a first intake manifold (34), and a second intake manifold (36). The engine system may also have a first exhaust manifold (40) connecting the first bank of cylinders to the first and second intake manifolds, a second exhaust manifold (42) connecting the second bank of cylinders to the atmosphere, a plurality of injectors, and a controller. The controller may be configured to inhibit the plurality of injectors associated with a first cylinder subset (52) of the first and second banks of cylinders from firing for a first period of time spanning multiple engine cycles. The controller may also be configured to selectively inhibit the plurality of injectors associated with a second cylinder subset (54) of the first and second banks of cylinders from firing for a second period of time following the first period of time.
