The length of the second intake passage (8) is longer than the length of the first intake passage (5) from a surge tank (1) to the connection point (S) between the second intake passage (8) and the first intake passage (5), and the passage cross-sectional area of the second intake passage (8) is smaller than the passage cross-sectional area of the first intake passage (5) from the surge tank to the connection point (S).

  • Patent number: 8118007
    Abstract: An L-shaped rotary valve has a pair of side plates and a valve plate. The rotary valve is rotatably supported in a housing at a shaft 5. The valve plate moves along downstream ends of side wall portions of an air duct. A gap is formed between a downstream end of an air-intake passage and the valve plate, when the rotary valve is moved to its valve closed position. The side plates of the rotary valve cover the gap in a lateral direction in parallel to an axial direction of the shaft, so that leakage of air flow in the lateral direction of the gap is suppressed.

  • Patent number: 8015958
    Abstract: An active intake manifold system includes at least one flap cartridge assembly having a unitary cartridge housing including one or more flap valve housings. A flap valve is rotatable in the aperture of the flap valve housing between an open state and a closed state. A shaft is provided extending through the mounting ear apertures of the flap valves so that the flap valves change state in unison. A plurality of air intake runners provides air flow communication between the outlets of the flap valve housings and the cylinder intake valves of the engine. Each intake runner includes a main runner portion that then splits into a plurality of tracts of differing lengths with each tract tuned to a different predetermined engine speed and having a length and volume selected to optimize engine performance at the predetermined speed. The flap valves may be automatically operated by an actuator under control of an engine control system.

  • Publication number: 20100269777
    Abstract: Improvements in an intake manifold for an internal combustion engine having separate plenum intake storage tanks. Each plenum stores an internal large volume of air that more easily drawn into intake conduits that feed air into the intake ports of an engine. Each plenum has one or more intake ports where air is supplied from a throttle body and a plurality of intake conduits. In the preferred embodiment there are three intake conduits that provide air for a total of six cylinders. The plenums are constructed from formed pieces to provide thinner walls thereby increasing the internal volume of the plenums. The plenums further have connection ports for sensors. The intake conduits terminate a distance within the plenum and have flared ends that can be oriented towards the center of the plenum to improve air movement and flow from the input.
