Abstract: A control system comprising a brake torque determination module that determines a desired brake torque and a vane position determination module that determines a vane position based on an engine speed and the desired brake torque, and that adjusts the vane position to a position between an open position and a closed position. A method comprising determining a desired brake torque, determining a vane position based on an engine speed and the desired brake torque, and adjusting the vane position to a position between an open position and a closed position.

Abstract: An engine control module includes a power module and a turbine temperature module. The power module controls engine power output based on a turbine temperature. The turbine temperature module determines the turbine temperature based on a turbine inlet temperature. The power module decreases the engine power output when the turbine temperature is greater than or equal to a predetermined threshold temperature.

Abstract: An intake throttle valve (ITV) position determination module generates a desired ITV position based on at least one of a desired airflow in a regeneration mode and an exhaust braking request in an exhaust braking mode. An ITV position limitation module generates a limited ITV position based on the desired ITV position. A transition module detects a transition from the exhaust braking mode to the regeneration mode, wherein an ITV is controlled to the limited ITV position after the transition is detected.

Abstract: An oil life monitoring system for a diesel engine system includes a viscosity loss module, a viscosity gain module, and a remaining oil life module. The viscosity loss module determines a percentage of viscosity loss of engine oil based on fuel accumulation in the engine oil. The viscosity gain module determines a percentage of viscosity gain of engine oil based on fuel evaporation and/or soot accumulation in the engine oil. The remaining oil life module communicates with the viscosity loss module and the viscosity gain module and determines a percentage of oil life remaining based on the percentage of viscosity loss and/or the percentage of viscosity gain.

Abstract: An engine control system comprises an engine speed control module and an idle limiting module. The engine speed control module selectively controls an engine based on an idle speed request. The idle limiting module selectively reduces the idle speed request by an amount that is based on a wheel slip value.
