Abstract: A supercharged engine and operating methods thereof are described for adjusting an extent of fluidic coupling between separate channels of a two-channel turbine. In one particular example, a longitudinally displaceable flow transfer valve is arranged for movement lateral to the exhaust airflow that provides coupling between the channels, a position of the flow transfer valve within a flow transfer duct controlling the extent of fluidic coupling in addition to the rate of exhaust-gas flow through a blow-off line that conducts airflow past a rotor of the two-channel turbine. In this way, the flow transfer valve according to the present disclosure advantageously allows for adjusting a mode of supercharging based on one or more engine conditions to control the extent of fluidic coupling using a simplified valve arrangement.

Abstract: An internal combustion engine system is provided herein. The internal combustion engine includes an active cylinder, a selectively deactivatable cylinder, the active cylinder and selectively deactivatable cylinder each coupled to an intake system and exhaust-gas discharge system, an exhaust-gas turbocharger having a turbine positioned in the exhaust-gas discharge system and a compressor positioned in the intake system, a blower positioned in the intake system downstream of the compressor, and a bypass line bypassing the blower and including a shut-off valve.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a supercharged internal combustion engine having at least two cylinder groups of at least one cylinder each, both cylinder groups being equipped with an exhaust pipe, and the two exhaust pipes being in communication with one another, and having two exhaust gas turbochargers, the turbines of which are connected in parallel, with their compressors connected in series, and having an exhaust gas recirculation line which upstream of one of the two turbines branches off from the exhaust pipe assigned to this turbine and opens out into the common intake line. An advantage of this invention is that it provides a supercharged internal combustion engine which overcomes the drawbacks which are known from the prior art and can be used to realize high exhaust gas recirculation rates and high boost pressures, in particular simultaneously, in all the load ranges of the internal combustion engine.
