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.

Abstract: An engine system includes an exhaust system fluidly connected to an electronically controlled engine. Exhaust from the engine may travel a first pathway through a turbine of a turbocharger, or a second pathway that bypasses the turbine. An electronically controlled wastegate vale is biased to close the second pathway. An electronic controller is in communication with the electronically controlled engine and the electronically controlled wastegate valve. The electronic controller is configured to execute a wastegate diagnostic algorithm to detect a stuck closed default condition of the electronically controlled wastegate valve, and derate the engine in response to detection of a stuck closed fault condition.
