摘要： System, apparatus, and methods are disclosed for controlling one or more actuators of an air handling system of an internal combustion engine. The one or more actuators are controlled in response to one or more feedforward references that are adjusted by a reference governor that predicts one or more operating parameters and imposes constraints on the one or more feedforward references to reduce the potential for violating limits on the one or more operating parameters.

摘要： An engine valve actuation mechanism for producing a variable engine valve event includes a cam, a rocker arm, a rocker arm shaft, an eccentric rocker arm bushing, and a bushing actuation device. The eccentric rocker arm bushing is disposed in an axial hole in the rocker arm, the rocker arm shaft being disposed in the eccentric rocker arm bushing with the rocker arm shaft and the eccentric rocker arm bushing having offset axial centerlines. One end of the rocker arm and the cam is connected to form a kinematic pair and the other end of the rocker arm is located above the engine valve with a gap between the cam and the engine valve. The bushing actuation device is placed in the rocker arm and drives the eccentric rocker arm bushing to rotate, and the rotation of the eccentric rocker arm bushing changes the gap to generate the variable engine valve event.

摘要： An exhaust brake includes a valve housing allowing an exhaust gas to flow therein. A butterfly gate is installed in the valve housing to block the exhaust gas flow and has a through hole for discharging a portion of the exhaust gas when a back pressure of the exhaust gas is equal to or higher than a reference pressure.

摘要： A system and method is disclosed for diagnosing a malfunctioning of a pressure sensor in an aftertreatment system of an internal combustion engine. A first value of a differential pressure across the particulate filter is measured during the identified fuel cut-off state of the internal combustion engine. An exhaust back pressure valve of the aftertreatment system is operated toward a predetermined closed position thereof, and a second value of a differential pressure across the particulate filter is measured. A difference between the second value and the first value is calculated, and a malfunctioning of the differential pressure sensor is identified when the calculated difference is higher than a predetermined threshold value thereof.
