摘要:
The invention relates to an exhaust gas control system (1) and an exhaust gas control method. Said exhaust gas control system (1) comprises an exhaust gas throttle valve (4) in an exhaust gas channel (5) and an actuation device (6) of said exhaust gas throttle valve (4) comprising an actuating rod (7). An exhaust gas pressure control device (8) controls the exhaust gas pressure (P 1 ) occurring upstream of the exhaust gas throttle valve (4) in the exhaust gas channel (5). Said actuating rod (7) also comprises a control actuator (9) that interacts with a pressure compensation volume (10). Said pressure compensation volume (10) is pneumatically connected to a throttle opening (11) upstream of the exhaust gas throttle valve (4).

This invention relates to an exhaust modulator in or to be fitted in the exhaust system of an engine, comprising a body (10) defining a flowpath therethrough for engine exhaust gases, a gate (44) in the exhaust flowpath movable between an open and a closed position, one or more bleed flowpaths (46) communicating between opposite sides of the gate, and flow control means (41) operable in response to one or more operating parameters to control the flow of exhaust gases along the said one or more bleed flowpaths so as to limit the back pressure applied to the engine to different predetermined levels as required for operation of the modulator in selected modes.
摘要:
A throttle valve for adjusting an amount of intake air to an internal combustion engine includes throttle shafts (32, 33; 73 - 75) disposed in an intake air passage (13) perpendicularly across the longitudinal axis of the air passage, and first and second valve members mounted on the throttle shafts for opening/closing about the throttle shafts independently of each other. By these first and second valve members, there are formed main air passages (61, 62) for causing air to flow in the intake air passage along the longitudinal axis of the intake air passage toward the internal combustion engine and auxiliary intake air passages (63, 64) for causing air to flow in the intake air passage substantially perpendicularly across the longitudinal axis of the air passage.

A variable flow control method and device between an air intake and a throttle comprise at least one one-way valve with suitable restoring function between the air intake and the throttle, especially for a car. Corresponding functions can be generated among the one-way valve, an air intake manifold and the throttle to adjust and control an engine so that the engine can rapidly get various rotating rates corresponding to various degrees of vacuum respectively as natural or original air taking can be effectively and rapidly accelerated when the accelerator is trampled rapidly, and reflect the improvement on performances responding to torsion and acceleration of the various rotating rates.

Ein Schaltsaugrohr (10) für Brennkraftmaschinen weist einen Ansaugkanal (11) mit einer Kurzschlußöffnung (16) auf. Die Kurzschlußöffnung (16) kann mit einer Schaltklappe (18,18') verschlossen bzw. geöffnet werden. Die Schaltklappe (18) ist durch eine nicht starre Verbindung mit einem Klappenhebel (20) verbunden. Die Verbindung zwischen dem Klappenhebel (20) und der Schaltklappe (18) wird von einer Platte (32) einerseits und einer Kalotte (26) andererseits gebildet. Hiermit wird eine einfach herstellbare und montierbare kippbare Verbindung zwischen der Schaltklappe (18) und dem Klappenhebel (20) hergestellt.
摘要:
Un corps de papillon pour dispositif d'injection comporte un boîtier dans lequel est ménagé un conduit d'admission (10) contenant un papillon (14) en forme de disque sensiblement circulaire, monté sur un arbre médian de rotation (12) autour d'un axe transversal au conduit et déplaçable entre une position d'ouverture minimum, éventuellement nulle, et une position d'ouverture maximum pour laquelle le papillon est orienté parallèlement à l'axe du conduit. Le conduit d'admission contient également un opercule (22) monté rotatif autour d'un axe (24) parallèle à celui du papillon décalé. L'opercule a une dissymétrie telle que l'air parcourant le conduit d'admission tend à amener une de ses ailes (28) dans une position où elle obture une fraction du conduit d'admission. L'opercule a une liaison mécanique avec le papillon qui provoque l'ouverture forcée progressive de l'opercule lorsque le déplacement du papillon à partir de sa position minimum dépasse un angle déterminé.
