摘要:
The invention describes a plastic embodiment for a suction system, whereby various configurations of said embodiment can be produced at low cost. According to the invention, a modular structured suction system is created. Said system comprises a plastic air distributor module which can be connected to an air feed pertaining to an internal combustion engine; several plastic, single-pieced suction pipe modules, whereby one end of the suction pipes is joined to the air distributor module and the suction pipes are respectively allocated to a combustion chamber of the internal combustion engine; in addition to at least one plastic single-pieced flange module that is connected to the other end of the suction pipe of at least one suction pipe module and which can be secured to the internal combustion engine.

An intake manifold includes an upper shell, a lower shell, and a middle shell that interconnects the upper and lower shells. The lower shell has a plurality of longitudinally spaced shell ports. Each shell port is adapted for installation over a corresponding intake port for an engine cylinder head. The upper shell has a plurality of runners that are used to guide air to the shell ports. The middle shell has a plurality of channels that interconnect the runners and the shell ports such that air can flow through the runner to the cylinder intake port. Fuel injector pockets are formed within the upper, middle, and lower shells with each of the pockets having an injector opening in communication with the corresponding shell port. An internal fuel rail, formed between the upper and middle shells, supplies fuel to each of the injector pockets. A fuel injector is installed into each injector pocket such that the injectors are substantially enclosed within the manifold. An internal wire harness rail, formed between the upper and middle shells, supports a wire harness that electrically connects each of the injectors to a power supply.

The objective is to provide a resin air intake system provided with an intake control valve which permits simplifying the mold structure and maintaining axis center precision. In an air intake manifold with air intake passages (13) and (14) are fabricated to be opened and provided with an intake control valve (31) supported by a shaft (30) having an axis in the direction perpendicular to the axes of the openings (16), the air intake manifold is molded from a resin comprising at least an air intake manifold proper (10) and an air intake manifold cluster (20) which have split faces for the two, the split face of the air intake manifold proper (10) is provided with groove (18) in a direction perpendicular to the axes of the openings (16), bearings (32) which slidably support shaft (30) are mounted to be in the grooves (19), and a projection which projects from the split face of the air intake manifold cluster is brought into contact with the bearings (32).
摘要:
La présente invention concerne un répartiteur d'admission d'air pour un moteur à combustion internes à deux rangées de cylindres disposées en V qui fournit une distribution d'air équilibrée pour l'ensemble des cylindres, à admission variable en continu pour optimiser le fonctionnement du moteur quelles que soient les conditions de régime et de charge du moteur, et qui peut être disposé de façon peu encombrante dans l'environnement du moteur. Le répartiteur comporte un tambour central rotatif (50) monté à l'intérieur dudit corps de répartiteur (14) et constitué d'éléments tubulaires rotatifs (25, 26) distincts, montés adjacents chacun en regard d'un orifice d'entrée (15', 16') d'un conduit d'admission externe (15, 16) s'étendant jusqu'à un cylindre correspondant du moteur. Il est caractérisé en ce que les éléments tubulaires rotatifs (25, 26) sont cylindriques, ont des dimensions sensiblement identiques et sont coaxiaux et en ce que ledit répartiteur comporte des moyens d'étanchéité (32) disposés entre les éléments tubulaires rotatifs (25, 26) et le corps de répartiteur (14), agencés pour réaliser l'étanchéité des conduits d'admission internes (30, 31).
摘要:
A turbocharged V type engine can be equipped with an exhaust gas recirculation cooler integrated into the intake manifold, so as to achieve efficiency, cost reductions and space economization improvements. The cooler can take the form of a tube-shell heat exchanger that utilizes a cylindrical chamber in the air intake manifold as the heat exchanger housing. The intake manifold depends into the central space formed by the two banks of cylinders on the V type engine, such that the central space is effectively utilized for containing the manifold and cooler.

A linkage device of a V-type internal combustion engine rotates a pair of drive shafts (5a, b) for changing openings of swirl control valves. The linkage device receives reciprocating motion from an actuator through a rod (7). A center lever (8) connected to the rod (7) changes the reciprocating motion to swing motion and transfers the swing motion to right and left links (9, 11). The right and left links (9, 11) are connected to the drive shaft through right and left levers (10, 12), respectively. The right and left links (9, 11) and the right and left levers (10, 12) change the swing motion to rotational motion and apply the rotational motion to the drive shafts (5a, b).

Für einen Sammler einer Sauganlage für einen V-Motor, der zylinderseitig mit Einlaßleitungen und ansaugseitig mit Ansaugrohren ausgerüstet ist und im Inneren mittels einer mittigen Trennwand mit einer Durchbrechung in Kammern unterteilt ist, wird zur Erzielung einer gleichmäßigen Verteilung eines betriebspunktabhängig zugeführten Abgas-Frischluftgemisches auf sämtliche Zylinder bzw. Einlaßleitungen vorgeschlagen, daß sämtliche Einlaßleitungen mit einer ersten Kammer in mediumsführender Verbindung stehen und daß beide betriebspunktabhängig ein Abgas-Frischluftgemisch zuführenden Ansaugrohre mit der zweiten Kammer mediumsführend verbunden sind.
摘要:
A silencer for an idle air bypass valve (12) in an internal combustion engine includes a grid (56) disposed between the outlet of the idle air bypass valve (22) and the intake manifold (14). The grid (56) acts to reduce the air velocity entering into the intake manifold (14) which dampens the vibration of a plastic manifold, thereby reducing noise generated.
