Abstract
An engine system is disclosed. The engine system may have a first bank of cylinders, a second bank of cylinders, a first intake manifold, and a second intake manifold. The engine system may also have a first exhaust manifold connecting the first bank of cylinders to the first and second intake manifolds, a second exhaust manifold 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 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 of the first and second banks of cylinders from firing for a second period of time following the first period of time.
