Estimating the term…
An example engine system is disclosed. The engine system may control a turbocharger of an internal combustion engine, and more particularly control a boost pressure provided by a turbocharger to an internal combustion engine. An example method for controlling a boost pressure provided by a turbocharger may include receiving a boost pressure demand and identifying a compressor speed demand to achieve the received boost pressure demand. The method may also include converting the compressor speed demand into a kinetic energy demand of the turbocharger rotating components and controlling the kinetic energy of the turbocharger rotating components to meet the kinetic energy demand by controlling power supplied by the turbine and the electric motor assist.
A method for controlling a boost pressure provided by a turbocharger, wherein the turbocharger includes turbocharger rotating components including a turbocharger shaft, a compressor for providing the boost pressure, and a turbine for driving the compressor through the turbocharger shaft, the turbocharger further including an electric motor assist for assisting in driving the compressor through the turbocharger shaft, and one or more actuators for controlling the boost pressure provided by the turbocharger, wherein during operation, the turbine and the electric motor assist are each capable of supplying power to the turbocharger shaft, and the compressor absorbs power to provide the boost pressure, the method comprising:
A non-transient computer readable medium storing program instructions that when executed by a processor, causes the processor to control a boost pressure provided by a turbocharger, wherein the turbocharger includes a compressor for providing the boost pressure, a turbine for driving the compressor through a turbocharger shaft, and an electric motor assist for assisting in driving the compressor through the turbocharger shaft, and one or more actuators for controlling the boost pressure provided by the turbocharger, wherein during operation, the turbine and the electric motor assist each capable of supplying power to the turbocharger shaft, and the compressor absorbs power to provide the boost pressure, the program instructions causes the processor to:
A method for controlling a boost pressure provided by a turbocharger, wherein the turbocharger includes a compressor for providing the boost pressure, a turbine for driving the compressor through a turbocharger shaft, and one or more actuators for controlling the boost pressure provided by the turbocharger, wherein during operation, the turbine supplies power to the turbocharger shaft, and the compressor absorbs power to provide the boost pressure, the method comprising:
