Methods and systems are provided for a turbocharger system. In one example, a system comprises an actuator configured to adjust a position of a plurality of guide vanes and a position of a coolant valve configured to adjust coolant flow through a turbine coolant jacket or a compressor coolant jacket.

Controlling the position of turbine guide vanes and of a coolant flow

An exhaust gas turbine is provided. The exhaust gas turbine includes a first turbine housing part having insulating material extending along an interior surface and a second turbine housing part having insulating material extending along an interior surface, the second turbine housing part coupled to the first turbine housing part to form a volute directing exhaust gas to a turbine wheel.

Assembled turbine housing

A turbocharged internal combustion engine is provided with at least a partially variable valve train on an intake side wherein the intake valves are controlled to optimize the actuation of a second inlet valve in relation to a first inlet valve for different load conditions.

Supercharged applied ignition internal combustion engine with exhaust-gas turbocharging and method for operating an internal combustion engine of said type

Embodiments for an engine coupled to a first turbocharger and a second turbocharger are provided. One example includes responsive to a first condition, deactivating a first turbine of the first turbocharger and meeting a boost demand via operation of the second turbocharger, and responsive to deactivating the first turbine, increasing a pressure at a compressor-side end of a bearing arrangement of a shaft of the first turbocharger. In this way, oil leakage from the bearing arrangement may be reduced.

Method for operating an internal combustion engine with parallel supercharging and with an activatable turbine, and internal combustion engine for carrying out a method of said type

The internal combustion engine is provided which may include a cylinder head, a turbine, and a turbine housing. The turbine housing may include an exhaust gas passage, at least one coolant fluid passage, and a wall between the passages. The wall may have a first area (A) disposed to absorb heat from an exhaust flow passing through the exhaust gas passage, and a second area (A) disposed to transfer heat from the wall to be absorbed by a coolant fluid flow passing through the at least one coolant fluid passage, wherein the following applies: A/A&#x2264;1.2.

Turbine housing

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.

Exhaust flow valve for twin-scroll turbine and operating methods thereof

There is provided an arrangement of an internal combustion engine with a sequentially parallel twin turbocharger, in which at least one turbocharger has an electrical energy converter which can be used optionally as a motor for driving a compressor in the lower rotational speed range of the internal combustion engine or as a generator for charging a connected battery.

Twin turbo engine

An engine having a cylinder head including an exhaust manifold at least partially integrated therein, the exhaust manifold including an inner separating wall fluidly dividing two merged exhaust lines, each merged exhaust line in fluidic communication with a different pair of adjacent cylinders, and an outer separating wall fluidly dividing a first exhaust line in direct fluidic communication with a first cylinder and a second exhaust line in direct communication with a second cylinder, a lateral width of the inner separating wall greater than the outer separating wall, the lateral axis perpendicular to a longitudinal axis traversing centerlines of each cylinder.

Internal combustion engine having an interference reducing exhaust manifold

A turbocharger arrangement in an internal combustion engine is provided. The turbocharger arrangement includes a turbocharger housing surrounding a sealed inner space and a shaft extending through the turbocharger housing. The turbocharger arrangement further includes a turbine wheel arranged on the shaft and driving a compressor unit, a bearing arrangement mounting the shaft in the turbocharger housing, an oil supply device lubricating the bearing arrangement, and a pressure changing unit in fluidic communication with the sealed inner space configured to adjust the pressure in the sealed inner space based on engine operating conditions.

Turbocharger arrangement for an internal combustion engine

The disclosure relates to an internal combustion engine which is optimized with regard to the cooling of a turbine. The engine has at least one cylinder head and block, forming at least one cylinder, and at least one turbine. Each cylinder has at least one exhaust opening for discharging the exhaust gases from the cylinder. An exhaust gas line is connected to each exhaust opening, the exhaust gas lines converging to produce at least one combined exhaust gas line, thereby forming at least one exhaust manifold, which opens into the at least one turbine having a turbine housing. The turbine has at least one flow channel conducting exhaust gas through the turbine housing, and at least one coolant passage integrated in the housing forming a cooling facility. At least one chamber is arranged between the at least one coolant passage and the at least one flow channel conducting exhaust gas.

Internal combustion engine with cylinder head and turbine

A method for operating an engine of a motor vehicle is provided. The method comprises operating at least one turbocharger, operating a start/stop automatic system which automatically switches off the internal combustion engine when a stop condition is met, and automatically starts the internal combustion engine when a starting condition is met, and when the stop condition is met, delaying the automatic switching off of the internal combustion engine by a predefinable delay time (&#x394;t). In one example, automatic shut off of the engine may be delayed in order ensure adequate cooling of the turbocharger.

Method for avoiding turbocharger damage

Embodiments for cooling a turbine of an engine are provided. In one example embodiment, an internal combustion engine comprises a turbocharger including a turbine having a coolant jacket integrated in a housing of the turbine, and an oil circuit coupled to the coolant jacket of the turbine. By cooling the turbine with the oil circuit, the turbine may be constructed from less-heat resistant materials.

Internal combustion engine with liquid-cooled turbine

A method controlling combustion modes of an engine with at least a first and second cylinder, the engine having a first actuator configured to control at least intake valves of the first and second cylinder and a second actuator configured to control at least exhaust valves of the first and second cylinders, the method comprising of sending a first signal to the first actuator which adjusts operation of at least intake valves of the first and second cylinder and a second signal to the second actuator which adjusts operation of at least exhaust valves of the first and second cylinder, said first and second signals sent at different crank angles, and transitioning combustion modes of said first and second cylinders, said combustion modes including spark ignition and homogeneous compression ignition.
