20090293850 | SUPERCHARGED ENGINE - A supercharged internal combustion engine is disclosed which includes a supercharger operatively connected to the crankshaft via a clutch supported by an intermediate shaft such that torque variations are partially absorbed by the clutch. | 12-03-2009 |
20100071673 | ENGINE WITH BELT/ALTERNATOR/SUPERCHARGER SYSTEM - An internal combustion engine for an automotive vehicle includes a belt, alternator, supercharger (BASC) power system having a positive displacement supercharger with coacting rotors, a belt drive from the engine to the supercharger, an overrunning clutch allowing the supercharger to overrun the belt drive, and a motor-generator connected to charge a battery when the motor-generator is overrunning the belt drive. The system allows electric overrun of the supercharger to increase engine charge air and power at low engine speeds, to electrically offset some parasitic losses and increase power at high engine speeds, to use supercharger inertia to drive the motor-generator and charge the battery during engine decelerations, and to electrically reduce belt drive loads by supplementing supercharger drive power during transmission downshifts that increase engine speed, and thus minimize “chirping” sounds due to belt slipping. | 03-25-2010 |

20120006305 | Supercharging device for compressing charge air for an internal combustion engine - A supercharging device for compressing charge air for an internal combustion engine having a scroll compressor is proposed, a displacement scroll ( | 01-12-2012 |
20120037132 | Method and device for operating an internal combustion engine having a compressor for compressing the air supplied to the internal combustion engine - In a method for operating an internal combustion engine having a compressor, the diagnosing of a clutch of the compressor is achieved without an additional sensor system. The compressor is turned on via the clutch, and a variable characterizing the air-mass flow to the internal combustion engine is ascertained. A first value of the variable characterizing the air mass flow before turning on the compressor is compared to a second value of the variable characterizing the air mass flow after turning on the compressor by closing the clutch, and an error is detected as a function of a deviation between the first value and the second value of the variable characterizing the air mass flow. | 02-16-2012 |
20130160749 | SUPERCHARGER COUPLING - A rotational element coupling device in a supercharger includes a rotatable output shaft having tapered external splines and an output shaft axis of rotation. A coupling disk has a disk axis of rotation coaxial with the output shaft axis of rotation, a tapered internally splined bore coaxial with the disk axis of rotation to engage the tapered external splines, and a plurality of apertures defined in the coupling disk parallel to the disk axis of rotation. A plurality of pins each have a disk end and a timing gear end distal to the disk end. The plurality of pins matingly engages with the coupling disk at the disk end of the pins via the plurality of apertures. A timing gear is fixed to a supercharger rotor for rotation therewith. The timing gear has a plurality of apertures disposed therein to matingly engage with the timing gear end of the plurality of pins. | 06-27-2013 |
20150047617 | VARIABLE SPEED HYBRID ELECTRIC SUPERCHARGER ASSEMBLY AND METHOD OF CONTROL OF VEHICLE HAVING SAME - A supercharger assembly includes a supercharger in series with an engine that has a crankshaft and has an air intake manifold defining a plenum through which air flow is provided to the engine. A supercharger is upstream of the plenum in air flow to the engine and has a first rotor rotatable with a first shaft and a second rotor rotatable with a second shaft. The supercharger assembly also includes an electric motor-generator that is selectively alternately operable as a motor and as a generator, and a planetary gearing arrangement having a first member operatively connected to the electric motor-generator, a second member connectable to be rotated by the engine crankshaft, and a third member operatively connected for rotation with the first shaft. The supercharger assembly has only two selectively engageable torque-transmitting mechanisms and a control system configured to control the electric motor-generator and the torque-transmitting mechanisms. | 02-19-2015 |
20150345413 | DRIVE ARRANGEMENT FOR AN ENGINE ANCILLARY SUCH AS A SUPERCHARGER - A supercharging arrangement for an internal combustion engine. The supercharging arrangement comprises a supercharger having a rotational drive input, and a transmission having a rotational drive input to receive drive from an internal combustion engine, and a rotational drive output connected to the input of the supercharger. The transmission includes a variator operatively connected between the input and the output of the transmission, which variator has an output that is driven at an operating ratio from an input. A control system operates to cause an engine to deliver an amount of torque that is indicated by the state of an input to the control system. The control system is further operative to set the operating ratio of the variator. | 12-03-2015 |
