    摘要： A vacuum pump onboard a vehicle provides vacuum for a brake booster and to control the electronic vacuum regulation valve (EVRV) valve of a wastegate on a turbocharger. Commands to the EVRV are based on an operating condition of an engine and the vacuum level in the vacuum system. In one example, a vacuum sensor is provided to determine vacuum proximate the EVRV. In another example, the vacuum proximate the EVRV is modeled based on the vacuum at the brake booster, which may be determined by a vacuum sensor coupled to the brake booster.

    摘要： Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, actuation of the wastegate is limited when outside a range, the limits of the range varying with boost pressure, turbine inlet pressure, turbine outlet pressure, and atmospheric pressure. In this manner, a tracking error may be reduced when controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration.

    摘要： A method for determining cylinder air charge and/or cylinder burned gas for an internal combustion engine system. The engine system includes cylinders, each one of such cylinders having at least one intake valve and at least one exhaust valve in communication with such cylinder. The method determines one of a plurality of different scenarios, each one of the scenarios representing a geometrical relationship between opening and closing of the intake valve relative to closing of the exhaust valve. The cylinder air charge and/or cylinder burned gas is calculated in accordance with the determined one of the plurality of scenarios. In one embodiment, the engine system stores a plurality of different software modules. The method selects one of the plurality of software modules in accordance with the determined one of the plurality of scenarios. The cylinder air charge and/or cylinder burned gas calculation comprises executing the selected one of the modules. In one embodiment, a memory stores a relationship between volume occupied by residual gas in the at least one cylinders at a predetermined position of the at least one cylinder in the engine during the cycle determined in accordance with each one of the plurality of scenarios for each of a plurality of different intake valve opening and exhaust valve closing conditions. The method includes: determining from the memory the volume occupied by residual gas in the at least one cylinders at a predetermined position of the at least one cylinder in the engine during the cycle for the intake valve opening and exhaust valve closing conditions; and, determining from volume occupied by residual gas in the at least one cylinders at a predetermined position of the at least one cylinder in the engine during the cycle the cylinder air charge and/or cylinder burned gas.

    摘要： A method for detecting improper operation of a charge motion control device (CMC) based on exhaust temperature is disclosed. It has been found that when the charge motion control device is switched between two positions, the exhaust temperature changes by as much as 100 degrees C. The expected exhaust temperature, based on commanded charge motion control device position and current engine operating condition, and the measured exhaust temperature are compared to determine whether the charge motion control device has failed to attain the desired position.
