Abstract:
In a variable intake apparatus for an internal combustion engine, each of a plurality of intake pipes (1) is separated from a surge tank (2) by a partition wall (3), and communication ports (31), provided in the partition wall (3) for the respective intake pipes (1), are opened and closed by respective variable intake valves (4) to adjust length of intake passages. In a valve housing (41) that retains the variable intake valves (4), a first rib (45) is formed in an area between each pair of the variable intake valves (4), in which a turning shaft (5a; 5b) is disposed and inserted. The first rib (45) is formed in parallel with the turning shaft (5a; 5b). The valve housing (41) includes a fastening portion (47) that is used to fasten the valve housing (41) to an upper cover (C) with a bolt (41a). A second rib (46) is formed in an area that is close to one of the communication ports (31) that is close to the fastening portion (47).
Abstract:
A supercharger (10) is positioned in the valley of an automobile engine (60) so that it fits under the engine hood (25) . The supercharger (10) has a low profile air inlet (14) at the top that passes air to an inlet tube (16) The height of the inlet tube (16) decreases and its width expands as the inlet tube (16) extends away from the air inlet (14) to keep a low profile while minimizing restrictions to airflow. The inlet tube (16) supplies air to a compressor (18) at the bottom. The pressurized air flows through a large and thin intercooler (24) directly above the compressor (18) . The cooled air is fed to long and straight intake manifold runners (28) positioned above the engine heads (61, 62) of the engine (60) . The supercharger (10) provides a large volume of low pressure and low temperature air charge to the engine (60) .
Abstract:
Saugmodul zum Betrieb einer brennkraftmaschine. Es wird ein Saugmodul (3) für ein Kraftfahrzeug vorgeschlagen, mit einem ersten Volumen, in dem sich über eine Einströmöffnung (4) angesaugte Luft sammelt, einem zweiten Volumen in dem sich die Luft verteilt und das zu den Einlassventilen führende Ansaugkanäle (5) enthält, einem Gehäuse das die beiden Volumina umgrenzt und einer Drosselvorrichtung (8). Erfindungsgemäss umfasst die Drosselvorrichtung (8) ein Trägermodul (9) und ein zugehöriges Drosselelement, welches zwischen dem ersten und dem zweiten Volumen des Saugmoduls (3) angeordnet ist. Anwendung in Kraftfahrzeugen, insbesondere Personenkraftwagen.
Abstract:
A rotor housing (2) has a flange (8) projecting in opposite axial directions of a rotor and having the suction flow outlet of a suction pipe (33) joined thereto integrally with the rotor housing (2). The rotor housing (2), collector housing (21) and suction pipe (33) are integrally formed of aluminum alloy casting. The lower surface of the flange (8) of the rotor housing (2) is used as an attachment surface to be attached to the upper surface of a cylinder head.
Abstract:
An engine intake manifold assembly (10), including a first component (12) having a first mating surface (14) and a second molded plastic component (16) having a second mating surface (18). The second molded plastic component (16) is adhesively bonded to the first component (12) with an adhesive (20).
Abstract:
A mounting arrangement and method for installing fuel injectors (30) in a molded composite intake manifold (24) having an integral fuel rail portion (32) in which the injectors are first assembled into bores (42) in the fuel rail portion, and the intake manifold advanced onto a cylinder head surface (26) having bores (38) extending perpendicularly into the surface so as to allow the tips of the fuel injectors to be seated therein at the same time as the manifold is mounted. Air assist passages (62) are also integrally formed in the intake manifold aligned with passages (66) in the cylinder head.
Abstract:
The present invention relates to an intake manifold structure including: an apparatus body in which an intake port is disposed; a surge tank part disposed inside the apparatus body and connected to the intake port; a runner part disposed inside the apparatus body and connected to the surge tank part; and a flow changing means disposed between the surge tank part and the runner part and adjusting a flow rate or direction of air flowing from the surge tank part to the runner part. According to the present invention, there is an effect of variably adjusting the amount of air flowing from the surge tank to the runner according to operation states.
