摘要： An exhaust-gas flap device, especially for the exhaust-gas flow of an internal combustion engine, has a flap pipe and a flap plate that is supported, in the interior of the flap pipe, on a pivot shaft that is rotatable about a pivot axis. The exhaust-gas flap device further includes a pivoting drive for the pivot shaft with a drive element. A coupling unit couples the drive element to the pivot shaft for conjoint rotation about the pivot axis. Vibration-damping material is arranged in the region of the coupling unit.

摘要： A mixture formation unit has a base body in which an intake channel section is formed. The intake channel section extends from a first end side of the base body to a second end side of the base body. The mixture formation unit has at least one rectilinearly extending channel which opens into the intake channel section. The channel opens at the first end side of the base body. The mixture formation unit is preferably provided for a two stroke engine whose intake channel is divided downstream of the mixture formation unit into a mixture channel and an air channel.

摘要： An internal combustion engine system includes a combustion engine configured to produce exhaust gases as a product of a combustion reaction. An exhaust discharge pipe coupled to the internal combustion engine, and an adaptive valve assembly. The adaptive valve assembly is coupled to the exhaust discharge pipe and configured to receive the exhaust gases prior to the exhaust gases reaching the atmosphere. The adaptive valve assembly includes a valve flapper arranged in the passageway and configured to pivot about a flapper pivot axis from a normally-closed position to an opened position.

摘要： A rotary control valve that includes a valve body, a valve shaft disposed within a bore of the valve body, a first valve seat disposed within the valve body, a first control element carried by the valve shaft, and a first pressure labyrinth at least partially defined by the first control element. The first control element is movably disposed in the first opening between a closed position, in which the first control element sealingly engages the first valve seat, thereby closing the first opening, and an open position, in which the first control element is spaced from the first valve seat, thereby opening the first opening. When the first control element is in the closed position, the first pressure labyrinth is configured to cause a pressure drop in fluid flowing therethrough, thereby minimizing an internal leak rate of the rotary control valve.
