摘要： A pulsation absorption system for a turbocharged engine is provided herein. The pulsation absorption system includes a pulsation absorption device coupled to an air passage at a position between a compressor and a turbine, wherein the pulsation absorption device is configured to selectively increase a volume of the air passage. In this way, it is possible to reduce surge while limiting increase in turbo lag.

摘要： Systems and methods for controlling air flow in an engine including a turbocharger are provided. One example method includes during a first operating range, operating the engine with a first exhaust valve duration at a first exhaust valve timing, during a second operating range, operating the engine with a second exhaust valve duration at a second timing, and during a third operating range, operating the engine with the first exhaust valve duration at a third timing, where engine load of the second operating range is higher than engine load of the first operating range, which in turn is higher than engine load of the third operating range, and where the first exhaust valve duration is longer than the second exhaust valve duration, and where the first timing is retarded to a greater extent than either of the second and third timings.

摘要： A method for controlling combustion in a combustion chamber of a turbocharged engine is described. The method includes admitting to the combustion chamber prior to ignition a first amount of exhaust from an intake manifold of the engine, the first amount changing at a first rate in response to a changing engine load. The method also includes retaining in the combustion chamber prior to the ignition a second amount of exhaust from the combustion chamber, the second amount changing at a second rate, greater than the first rate, in response to the changing engine load.

摘要： A four-stroke cycle reciprocating internal combustion engine includes a piston mounted for reciprocal movement within a power cylinder and primary and secondary intake valves. The primary valve has a fixed event, in terms of both duration and lift, and the secondary valve has variable duration and lift. Although the timing of the primary and secondary valve events may be retarded from a standard timing value, both valves close at the same time regardless of the presence of timing retard. The dual event strategy, combined with camshaft timing retard for part load conditions, produces excellent charge motion by staggering the respective lifted flow areas of the primary and secondary valve events and by delaying the secondary valve opening.
