  • Engine control system for increased vehicle fuel economy
    Patent number: 8584647
    Abstract: An engine control system comprises a driver input module, a cylinder actuation module, and an active fuel management (AFM) module. The driver input module generates a fuel saver mode (FSM) signal having a first state based upon a driver input. The cylinder actuation module selectively disables at least one of a plurality of cylinders of an engine based upon a deactivation signal having a first state. The AFM module generates the deactivation signal based on at least one engine parameter and at least one threshold. The at least one threshold is modified when the FSM signal has the first state.

  • Fluid entrainment apparatus
    Patent number: 7637099
    Abstract: A fluid entrainment apparatus is provided which operates to mix a first fluid stream with a second fluid stream. The apparatus includes first and second fluid flow conduits. The first fluid flow conduit includes a nozzle portion having a converging bore through which the first fluid is accelerated. Additionally, the second fluid flow conduit includes a nozzle portion having a converging bore, a duct portion having a generally cylindrical bore, and a diffuser portion having a diverging bore. The nozzle portion of the second fluid flow conduit is mounted with respect to the nozzle portion of the first fluid flow conduit such that an annular port is formed through which the second fluid passes to mix with the first fluid. Additional fluid mixing occurs in the duct portion and the diffuser portion. The fluid entrainment apparatus may be configured for use within a vehicle exhaust system.
