Internal combustion engines for hybrid powertrain

摘要: A hybrid power train and method for operating same in which the operation of engine is modified to effect an improvement fuel economy and/or emissions performance train. In one embodiment, battery employed provide auxiliary heat aftertreatment system thereby improve effectiveness system. another various components engine, such as a water pump, are wholly or partly operated by electric motors that receive from braking can be situations where regenerative does not sufficient torque. further valves may selectively opened reduce pumping losses associated with back-driving engine.
