20100326406 | TWIN FLOW SUPERCHARGED ENGINE - Systems and methods for operating a twin flow supercharged engine are provided. The exhaust lines of engine cylinders are grouped into separate manifolds connected to respective inlet ducts of the twin-flow turbine. The inlet ducts of the twin-flow turbine are of different sizes, with different-sized cross sections and/or different-sized exhaust-gas volumes. The exhaust line of a manifold with a smaller exhaust-gas volume is connected to the larger inlet duct, and the exhaust line of a manifold with the larger exhaust-gas volume is connected to the smaller inlet duct. | 12-30-2010 |
20140196696 | SUPERCHARGED INTERNAL COMBUSTION ENGINE WITH TWIN-FLOW TURBINE AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF SAID TYPE - A supercharged internal combustion engine may include a twin-flow turbine with variable vane geometry. One example method to operate the device permits optimized operation of the internal combustion engine at low exhaust gas flow rates. | 07-17-2014 |
20140230431 | SUPERCHARGED INTERNAL COMBUSTION ENGINE WITH TWO-CHANNEL TURBINE AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF SAID TYPE - A supercharged internal combustion engine comprising a two channel turbine fluidly connects the two channels within the turbine housing by virtue of at least one opening in the housing wall which separates the two channels wherein at least one displaceable wall part is provided which serves for opening up the opening in the housing wall to optimize the performance of the turbine responsive to the exhaust gas flow rate. | 08-21-2014 |
20140230432 | SUPERCHARGED INTERNAL COMBUSTION ENGINE WITH TWO-CHANNEL TURBINE AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF SAID TYPE - A supercharged internal combustion engine wherein a two-channel turbine comprising a shut-off body positioned within a flow transfer duct within a turbine housing fluidly couples the two channels of a turbine housing to one another via the transfer duct responsive to the exhaust gas flow rate to enable better operation of the turbocharger. | 08-21-2014 |
20140331667 | INTERNAL COMBUSTION ENGINE WITH DEACTIVATABLE CYLINDER, AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF SAID TYPE - A method and system is provided for a turbocharged multi-cylinder internal combustion engine comprising a two-channel turbine and at least two groups of cylinders, wherein one group of cylinders is switchable responsive to an engine load over a threshold. Exhaust lines of each group of cylinders are arranged in a targeted manner to couple with the turbine such that the switchable group is attached to one channel and the active group is attached to the other channel to reduce the difference in distances that pressure pulses travel, wherein a shut-off element is provided in the channel attached to the switchable group and may be moved to block exhaust flow through the channel when the cylinders are deactivated, thus improving the partial deactivation and turbocharging characteristics of the engine. | 11-13-2014 |
20140374498 | VEHICLE HEATING SYSTEM AND METHOD OF USING THE SAME - In one or more embodiments, the present invention provides a vehicle heating system for a vehicle with an engine and a charge air cooler, the vehicle heating system including a high-temperature cooling circuit coupled to the engine, a low-temperature cooling circuit coupled to the charge air cooler and including a low temperature cooler, and a heating heat exchanger coupled to the low-temperature cooling circuit. | 12-25-2014 |
20150013330 | SYSTEM AND METHOD FOR VARIABLE TONGUE SPACING IN A MULTI-CHANNEL TURBINE IN A CHARGED INTERNAL COMBUSTION ENGINE - An internal combustion engine comprising a dual flow turbocharger includes an annular support with at least one tongue-like end wherein the annular support is adjustable in a translational fashion along the turbines axis of rotation. Moving the annular support influences the degree of separation behavior of turbine channels by varying a tongue spacing to the rotor. | 01-15-2015 |
20150075159 | SUPERCHARGED INTERNAL COMBUSTION ENGINE WITH EXHAUST-GAS TURBOCHARGERS ARRANGED IN SERIES AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF SAID TYPE - A supercharged internal combustion engine, comprising a high-pressure turbine connected to a channel of a low-pressure turbine and a bypass line, branching from upstream the high-pressure turbine, connectable to the channels of the low-pressure turbine via a control element positioned within the bypass line, is provided. Adjusting the control element fluidly connects each of the channels of the low-pressure turbine to the bypass line responsive to the exhaust-gas flow rate to optimize the performance of the engine. | 03-19-2015 |
