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 |
20150204279 | BOOSTED INTERNAL COMBUSTION ENGINE WITH PARTIAL DEACTIVATION AND METHOD FOR THE OPERATION OF AN INTERNAL COMBUSTION ENGINE OF SAID TYPE - 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. | 07-23-2015 |
20150233283 | EXHAUST FLOW VALVE FOR TWIN-SCROLL TURBINE AND OPERATING METHODS THEREOF - 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. | 08-20-2015 |
20150267624 | METHOD FOR PERFORMING A CHARGE EXCHANGE IN AN INTERNAL COMBUSTION ENGINE - A method and system for perform a charge exchange in internal combustion engine comprising an additional intake and exhaust valve lifts performed during positive pressure gradients between the intake and exhaust systems to reducing scavenging losses and increase torque during low engine speeds. | 09-24-2015 |
20150285163 | METHODS FOR TURBOCHARGED ENGINE WITH CYLINDER DEACTIVATION AND VARIABLE VALVE TIMING - A system and methods are described for a turbocharged engine, comprising powering the engine using a first operating cylinder, supplementing the power using a second switchable cylinder, deactivating the second switchable cylinder responsive to a load below a first threshold, and closing a first shut-off element downstream of a compressor during the partial deactivation to prevent a first turbocharger from imparting a delivery action into a second compressor during the partial deactivation. Embodiments are further described wherein a bypass line in a second exhaust line further serves as a short-circuit line to prevent the second compressor from imparting a delivery action against the closed first shut-off element. A variable valve timing is then included to further optimize the combustion process during the partial deactivation. | 10-08-2015 |
