The application relates to internal combustion engines, cylinder heads, exhaust passages, and shapes and configurations of the exhaust passages. The exhaust passage may have cross-sectional shapes formed by two limbs. The cross-sectional shape of the exhaust passage may change as the passage extends. The exhaust passage may also merge with other exhaust passage. The exhaust passage may be part of a cylinder head or an exhaust manifold.

Internal combustion engine with cylinder head, and method for producing a cylinder head of an internal combustion engine of said type

A method for varying a compression ratio &#x3b5; of an operating applied-ignition internal combustion engine having at least two cylinders and having a crank mechanism () comprising a crankshaft () which is mounted in a crankcase and which rotates at a crankshaft rotational speed &#x3a9;, is described. The method includes increasing an expansion phase of a cylinder cycle via rotation of the eccentric bushing ().

Method for varying a cylinder-specific compression ratio of an applied-ignition internal combustion engine and internal combustion engine for carrying out a method of said type

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

A method for controlling valve actuation in an engine is provided. The method includes initiating combustion operation in a first cylinder, opening, via a first cam, a first exhaust valve coupled to the first cylinder for a first opening duration. The method further includes opening, via a second cam, a second exhaust valve coupled to the first cylinder for a second opening duration not equivalent to the first opening duration.

Internal combustion engine having a plurality of exhaust ports per cylinder and charge exchange method for such an internal combustion engine

An exhaust system for an internal combustion engine is provided. The system comprises an exhaust tract which is connectable to an outlet side of the internal combustion engine, at least one catalytic converter arranged in the exhaust tract downstream of the engine, a particle filter downstream of the at least one catalytic converter, and a secondary-air inlet port provided in the exhaust tract upstream of the particle filter for introducing compressed secondary air into the exhaust tract via at least one flutter valve. In this way, additional oxygen may be supplied to the particulate filter to perform filter regeneration.

Exhaust system for internal combustion engines with particle filter

A cylinder head has at least three cylinders each coupled to at least one exhaust port, individual exhaust ducts coupled to each of the exhaust ports, and a combined exhaust duct coupling all individual exhaust ducts. The combined exhaust duct emerges from the cylinder head at a location displaced longitudinally from a center of the cylinder head.

Cylinder head for an internal combustion engine

A cylinder head for an internal combustion engine has at least two cylinders, each cylinder having an outlet opening for discharging the exhaust gases out of the cylinder, an assembly end side for connection to a cylinder block of the engine, an exhaust-gas line adjoining each outlet opening, the exhaust-gas lines of the at least two cylinders merging within the cylinder head to form a combined exhaust-gas line, and a coolant jacket interior to and at least partially integrated in the cylinder head, the coolant jacket made up of a lower coolant jacket and an upper coolant jacket, and at least one connection between the lower coolant jacket and the upper coolant jacket immediately adjacent the combined exhaust-gas line for allowing the passage of coolant.
