摘要:
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.

摘要:
A supercharged internal combustion engine comprising a two channel turbine fluidly connects the two channels within the turbine housing by virtue of at least one opening in the housing wall which separates the two channels wherein at least one displaceable wall part is provided which serves for opening up the opening in the housing wall to optimize the performance of the turbine responsive to the exhaust gas flow rate.
摘要:
A method includes deactivating one or more cylinders of the second cylinder group responsive to engine operation in a first engine speed-load region, and adjusting exhaust valve timing of one or more cylinders of the first cylinder group responsive to the deactivating. The method further includes adjusting exhaust valve timing of the one or more cylinders of the first cylinder group responsive to engine operation in a second engine speed-load region, and deactivating the one or more cylinders of the second cylinder group responsive to the adjusting.

Embodiments for operating an engine in a partial deactivation mode are provided. In one example, a method for an engine having a first cylinder group and a second cylinder group includes responsive to engine operation in a first engine speed-load region, deactivating one or more cylinders of the second cylinder group, and responsive to the deactivating, adjusting exhaust valve timing of one or more cylinders of the first cylinder group. The method further includes responsive to engine operation a second engine speed-load region, adjusting exhaust valve timing of the one or more cylinders of the first cylinder group, and responsive to the adjusting, deactivating the one or more cylinders of the second cylinder group.
