DUAL WASTEGATE ACTUATION

摘要

Various systems and methods for controlling dual wastegates via a single wastegate actuator are provided. In one example, a system comprises a first wastegate comprising a first wastegate valve, a second wastegate comprising a second wastegate valve, and a wastegate actuator coupled to each of the first and second wastegate valves to vary openings of the first wastegate valve and the second wastegate valve according to desired boost.
