摘要： 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.

摘要： 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.

摘要： A method for varying a compression ratio ε of an operating applied-ignition internal combustion engine having at least two cylinders and having a crank mechanism (1) comprising a crankshaft (2) which is mounted in a crankcase and which rotates at a crankshaft rotational speed Ωcrankshaft, is described. The method includes increasing an expansion phase of a cylinder cycle via rotation of the eccentric bushing (4).

摘要： A motor vehicle is provided which has an engine, an inlet air section for supplying the engine with inlet air, a compressor arranged in the inlet air section and a vortex generator arranged in the inlet air section upstream of the compressor. The vortex generator has at least one guide vane for generating a vortex in the inlet air and a vortex generator outlet having a first radius. The compressor has a compressor inlet having a second radius, which is smaller than the first radius. According to the invention, an exhaust gas recirculation line opens downstream of the vortex generator outlet and upstream of the compressor inlet.

摘要： 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.
