| 20090071431 | Intake manifold - An intake manifold for supplying intake air to an internal combustion engine includes a surge tank for temporarily storing the intake air, an air-intake port through which the intake air will be introduced in the surge tank, the air-intake port being provided in the surge tank at a position closer to an outer cylinder of the internal combustion engine than a center of the surge tank in its longitudinal direction, a plurality of branch intake passages having inlets arranged in parallel in the surge tank, each passage being configured to supply the intake air introduced in the surge tank through the air-intake port to each cylinder of the internal combustion engine through each inlet, and a guide wall provided in the surge tank and configured to change a flow direction of the intake air introduced in the surge tank to direct the intake air toward specific one(s) of the inlets of the branch intake passages. | 03-19-2009 |
| 20090084336 | Air intake system for internal combustion engine - A stepless air intake system is disposed on a throttle body of an engine. Each of plural cylinders has an intake tract to funnel air for combustion. | 04-02-2009 |
| 20090165740 | VEHICLE INCLUDING A VARIABLE INTAKE PIPE LENGTH DEVICE - Disclosed herein is a vehicle including a variable intake pipe length device capable of adjusting the length of an intake pipe according to the condition of an engine, the intake pipe being provided in an intake passage for inducing air from an air cleaner box to an intake port of the engine, the intake pipe including a fixed funnel and a movable funnel movable relative to the fixed funnel by a driving force of an actuator, wherein the actuator is located inside of an envelope formed by the contour of the intake pipe. | 07-02-2009 |
| 20090165741 | VEHICLE INCLUDING A VARIABLE INTAKE PIPE LENGTH DEVICE - A vehicle includes a variable intake pipe length device capable of adjusting the length of an intake pipe according to the condition of an engine, the intake pipe being provided in an intake passage for inducing air from an air cleaner box to an intake port of the engine, the intake pipe including a fixed funnel and a movable funnel movable relative to the fixed funnel by a driving force of an actuator. A rotating pipe as a part of the intake pipe is rotationally driven by the actuator, and the movable funnel is moved by rotating the rotating pipe, thereby varying the length of the intake pipe. | 07-02-2009 |
| 20090194055 | VARIABLE INTAKE APPARATUS FOR INTERNAL COMBUSTION ENGINE - In a variable intake apparatus for an internal combustion engine, each of a plurality of intake pipes is separated from a surge tank by a partition wall, and communication ports, provided in the partition wall for the respective intake pipes, are opened and closed by respective variable intake valves to adjust length of intake passages. In a valve housing that retains the variable intake valves, a first rib is formed in an area between each pair of the variable intake valves, in which a turning shaft is disposed and inserted. The first rib is formed in parallel with the turning shaft. The valve housing includes a fastening portion that is used to fasten the valve housing to an upper cover with a bolt. A second rib is formed in an area that is close to one of the communication ports that is close to the fastening portion. | 08-06-2009 |
| 20090272355 | Intake Control Device for Internal Combustion Engine - An intake control device for an internal combustion engine having a first intake passage ( | 11-05-2009 |
| 20100186705 | ACTIVE INTAKE MANIFOLD FLAP CARTRIDGE AND METHOD - 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. | 07-29-2010 |
| 20100294227 | INTAKE MANIFOLD SYSTEM FOR INTERNAL COMBUSTION ENGINE - An intake manifold system for an internal combustion engine includes inlet runners attached to a mounting flange. The inlet runners may be one piece with the mounting flange. A charge air control is mounted within the mounting flange, with the charge air control including a control shaft passage formed in the mounting flange, and a control shaft extending the length of the control shaft passage. The control shaft is journaled within the control shaft passage and carries a number of charge air control elements mounted for rotation with the control shaft. | 11-25-2010 |
| 20140338628 | TORQUE INCREASE RESONATOR - A torque increase resonator includes: a plurality of resonance pipes that extend outward from an intake passage supplying air to an internal combustion engine; one resonance chamber that is formed so that end portions of extending portions of the plurality of resonance pipes are positioned in an internal space of the resonance chamber; and a valve that opens and closes an opening of the extending portion of at least one resonance pipe of the plurality of resonance pipes, wherein the intake passage and the resonance chamber communicate with each other through the plurality of resonance pipes, and the plurality of resonance pipes are close to each other, and are disposed on a downstream side of a throttle in a flow direction of air in the intake passage. | 11-20-2014 |
| 20150047595 | INTAKE DEVICE - An intake device includes: an intake port; a valve body which is disposed in the intake port and rotated around a rotating shaft between an opening position and a closing position; and a seal surface which is integrally provided at the intake port and made up of an inner wall surface with which the valve body comes into contact at the closing position of the valve body, wherein the seal surface includes a first seal surface having an inner contact portion which protrudes to the inside of the intake port and a first outer contact portion which is located further to the outside than the inner contact portion, and a second seal surface having a second outer contact portion without having the inner contact portion. | 02-19-2015 |
