Abstract: A system, method and apparatus for multi-fuel, range extending power generation applied to propulsion in a vehicle. One or more fluid fuels including diesel and natural gas and/or their renewable counterparts of Biodiesel or Renewable Natural Gas are stored on board a vehicle and selectively supplied to an onboard electrical generator according to sensor measurements analyzed by a processor directing power generation and transmission to motor controllers and motors providing vehicle propulsion. The combined natural gas-electric and diesel-electric transmissions control system power generation driving electric motors rather than a diesel engine mechanical connection to axles and wheels. This integrated system provides improved extended range to diesel hauling applications with improved emissions while maintaining torque, and efficiency.

Abstract: A movable wall member is mounted in the intake runner of an internal combustion engine manifold and connected to an actuator plate in the manifold plenum which moves the wall member in a longitudinal direction to increase the effective runner length. A rigid link or end panel is pivotally connected to the other end of the wall member and to the associated runner wall so that longitudinal movement of the wall member results in simultaneous transverse movement thereby reducing the effective cross-sectional flow area of the runner passage. The movable wall members of multiple runner passages are connected to a common actuator plate in the manifold plenum which reduces the effective plenum volume upon displacement of the actuator plate.
