060609000 | Fluid motor and engine each drive at least one means to supercharge the engine | 6 |
20120090319 | COMPOUNDED DILUTION AND AIR CHARGING DEVICE - An internal combustion engine includes a turbocharger and a selectively operable positive displacement supercharger downstream of the turbocharger in the intake path. An input shaft of the supercharger is mechanically coupled to and driven by a piston-driven crankshaft. A bypass valve is configured to selectively bypass at least a portion of the air from the turbocharger air outlet around the supercharger. Power and fuel consumption are optimized by operating the supercharger to dilute the fuel-air mixture to achieve an excess air factor λ above 1.0, and in some cases above the upper range (λ=1.3) of normal stoichiometric operation. The engine can operate in a lean low temperature combustion mode (e.g., HCCI) with the supercharger operating, and in a stoichiometric spark ignition combustion mode with the supercharger bypassed. | 04-19-2012 |
20120144825 | DEVICE FOR SUPPORTING A SUPERCHARGING DEVICE - A device for utilizing the waste heat of an internal combustion includes a single-stage or multi-stage supercharging device, which is designed as an exhaust-gas turbocharger in particular. The single-stage or multi-stage supercharging device is assigned an additional supercharging device including an expansion machine acted upon by an auxiliary circuit, in particular a steam circuit. | 06-14-2012 |
20120186248 | SUPERTURBOCHARGER CONTROL SYSTEMS - Disclosed is a control system and method for controlling a superturbocharged engine system in various operation modes. Throttle control mode may idle the superturbocharger during low and medium engine loads, so that boost is not created in the intake manifold. During high engine load conditions (open throttle), boosting occurs in response to the driver, operator, or control system requesting increased engine loads. For transient control mode, the control system may respond to transient conditions in response to engine speed and load so that the engine does not bog down or overcome vehicle traction limits. The control system may also predict future operating points. For steady state control mode, the control system may receive a plurality of input data, an actual/current control data input, look up a desired value for the control input, compare the desired to the actual control input, and perform control logic on the comparison results to obtain an updated continuously variable transmission ratio to control the superturbocharged engine system independent of throttling on the engine. | 07-26-2012 |
20130298554 | SYSTEM AND METHOD FOR CONDITIONING INTAKE AIR TO AN INTERNAL COMBUSTION ENGINE - A system for conditioning the intake air to an internal combustion engine includes a means to boost the pressure of the intake air to the engine and a liquid cooled charge air cooler disposed between the output of the boost means and the charge air intake of the engine. Valves in the coolant system can be actuated so as to define a first configuration in which engine cooling is performed by coolant circulating in a first coolant loop at one temperature, and charge air cooling is performed by coolant flowing in a second coolant loop at a lower temperature. The valves can be actuated so as to define a second configuration in which coolant that has flowed through the engine can be routed through the charge air cooler. The temperature of intake air to the engine can be controlled over a wide range of engine operation. | 11-14-2013 |
20140260244 | CENTRIFUGAL SUPERCHARGER AND SUPERCHARGING SYSTEM FOR ENGINE USING THE SAME - A centrifugal supercharger includes, a drive pulley connected to receive rotating power from an engine. an electronic blocking the rotating power to be supplied to the drive pulley or supplying the rotating power to the drive pulley. a speed increasing device increasing rotation speed of the drive pulley. a compressor including an impeller receiving rotation power having speed increased by the speed increasing device and flowing and compressing external air and an impeller housing. | 09-18-2014 |
20150361871 | SYSTEM, APPARATUS AND METHODS FOR DIVERTING AIRFLOW TO A PRESSURE SOURCE - Systems, apparatus, and methods are disclosed for diverting a portion of intake airflow from a pressure source in an internal combustion engine system. The intake airflow is diverted to, for example, an air compressor at the intake of the pressure source before the airflow is pressurized by the pressure source. | 12-17-2015 |
