Abstract
Official abstract text for this publication.
A rotary device is coupled to the rotary mechanism of a turbocharger for selectively adding torque to and subtracting torque from the rotary turbocharger mechanism. A controller causes the rotary device to apply torque to the rotary turbocharger mechanism which causes the compressor to operate at a power level which creates a target pressure in the intake manifold different from existing pressure in the intake manifold.
First claim
Opening claim text (preview).
What is claimed is: 1 . An internal combustion engine comprising: engine cylinders within which fuel is combusted to operate the engine; an intake system, including an intake manifold, through which air enters the engine cylinders to support combustion; an exhaust system through which exhaust resulting from combustion leaves the engine cylinders; a turbocharger comprising a turbine in the exhaust system, a compressor in the intake system, and a rotary turbocharger mechanism operated by exhaust flow through the turbine for operating the compressor to compress air flow through the intake system and create pressure in the intake manifold exceeding ambient atmospheric pressure; a rotary device coupled to the rotary turbocharger mechanism for selectively adding torque to and subtracting torque from the rotary turbocharger mechanism; and a controller for processing, as the engine operates, data representing certain engine operating parameters according to an algorithm for calculating a quantity of power which the rotary drive is to selectively add to or subtract from power being produced by the turbine to cause the compressor to operate at a power level which creates a target pressure in the intake manifold different from existing pressure in the intake manifold, and for causing the rotary device to apply torque to the rotary turbocharger mechanism which causes the compressor to operate at the power level which creates the target pressure in the intake manifold different from existing pressure in the intake manifold. 2 . A method of turbocharging an internal combustion engine which has engine cylinders within which fuel is combusted to operate the engine, an intake system, including an intake manifold, through which air enters the engine cylinders to support combustion, an exhaust system through which exhaust resulting from combustion leaves the engine cylinders, and a turbocharger comprising a turbine in the exhaust system, a compressor in the intake system, and a rotary turbocharger mechanism operated by exhaust flow through the turbine for operating the compressor to compress air flow through the intake system and create pressure in the intake manifold exceeding ambient atmospheric pressure, the method comprising: controlling a rotary device coupled to the rotary turbocharger mechanism for selectively adding torque to and subtracting torque from the rotary turbocharger mechanism by processing, as the engine operates, data representing certain engine operating parameters according to an algorithm for calculating a quantity of power which the rotary drive is to selectively add to or subtract from power being produced by the turbine to cause the compressor to operate at a power level which creates a target pressure in the intake manifold different from existing pressure in the intake manifold; and causing the rotary device to apply torque to the rotary turbocharger mechanism which causes the compressor to operate at the power level which creates the target pressure in the intake manifold different from existing pressure in the intake manifold.
