摘要： An internal combustion engine is provided with a variable valve train (30, 31) capable of altering opening and closing timings and/or opening amounts of at least one of an intake valve (28) and an exhaust valve (29) of an internal combustion engine. The internal combustion engine is further provided with a negative pressure mechanism (100) that operates using intake pipe negative pressure generated in an intake passage (33, 34, 35) of the internal combustion engine, a throttle valve (39) for adjusting the flow rate of intake air flowing through the intake passage (33, 34, 35), and negative pressure generating means (20) for controlling at least one of the variable valve train (30, 31) and the throttle valve (39) to generate the intake pipe negative pressure, when the intake pipe negative pressure for operation of the negative pressure mechanism (100) is insufficient.

摘要： The invention concerns a method and a device for simultaneous regulation of an intake air flow (24) of an internal combustion engine (10) and a secondary air flow (21) in the exhaust system (12) of the internal combustion engine, wherein the secondary air flow is produced by a compressor (20) powered by a turbine (18). The turbine (18) is mounted in a bypass (16), wherein said bypass is disposed parallel to a throttle valve (14) in the intake tract (11) of the internal combustion engine. The amount (21) of secondary air supplied thereby depends on the position of the throttle valve. In order to provide compensation therefor, a regulating valve (32) is provided, which is connected to the secondary air line (22) by means of a connecting line (34). The regulating valve influences the cross section of the bypass (16) so that the cross section of the bypass can be simultaneously widened when the throttle valve (14) is opened, whereby a pressure drop in the turbine caused by the opening of the throttle valve can be compensated for. In another embodiment, a control valve that is controlled by a control unit can also be mounted, wherein mechanical coupling of the throttle organ in the bypass and the throttle valve is also possible. The disclosed method enables simultaneous regulation of intake air flow and secondary air flow with acceptable structural complications thereby representing an economical solution.

摘要： The invention relates to an internal combustion engine comprising at least one line system for secondary air. A module body comprises a portion of the lines (25, 30, 35), a portion of the actuating valves (26a, 31, 26b), and check valves (27). The throttle valve (13) and its actuator (36) are additionally integrated in said module. A line section (14) which is part of the intake system (11) is also integrated in the module. The admissions of the lines (35, 30) are easily realized in said line section. The line (30) is intended for recirculating exhaust gas. It is also possible to partially realize the depicted idea with regard to integration. It is also possible to simultaneously utilize the supply line (29) in the exhaust (21) of the internal combustion engine as a bleed line for the exhaust gas. All of these measures are suited for reducing the installation space and the number of components for the internal combustion engine, whereby they yield very economical solutions.

摘要： An alternator assembly (100) for use with a port fuel injected internal combustion engine (102) including a battery charging system is driven by a turbine assembly (104) mounted in a variable air intake (116) or throttle valve assembly and converts the change in kinetic energy provided by the inlet combustion air movement across the turbine assembly (104) into rotational movement which drives an electrical generating assembly (106) or alternator to generate current which can be used to supplement a conventional vehicle battery charging system (122).

摘要： An arrangement in a throttle-controlled internal combustion engine (1, 2) equipped with a supercharger which has the form of a compressor (10) provided with screw rotors (14, 15) arranged in a compression chamber. The supercharger is inactive at part engine loads, and since the engine normally operates at part loads for about 95% of its running time, efficiency is correspondingly poor. This drawback is overcome with the arrangement according to the invention, which is mainly characterized in that the screw compressor (10) is provided on the inlet side (20) thereof with a capacity regulating device (22) which is operated by the gas pedal, or accelerator, and which when the engine is only partially loaded is adjusted to a corresponding position in which the compressor (10) operates as an expander (3) of variable throttle effect on the engine inlet side (3) and transmits power to the engine, therewith replacing the conventional gas throttle.

摘要： Agencement dans un moteur à combustion interne (1, 2) doté d'une commande des gaz et équipé d'un surcompresseur ayant la forme d'un compresseur (10) pourvu de rotors hélicoïdaux (14, 15) disposés dans une chambre de compression. Le surcompresseur est inactif dans le cas de charges partielles du moteur, et puisque le moteur est soumis à des charges partielles pendant à peu près 95% de son temps de fonctionnement, le rendement est en conséquence médiocre. Cet inconvénient est éliminé avec l'agencement ci-décrit, lequel est principalement caractérisé par le fait que le compresseur (10) à rotors hélicoïdaux est pourvu du côté admission (20) d'un dispositif de régulation de capacité (22) qui est commandé par la pédale des gaz ou l'accélérateur, et qui, lorsque le moteur n'est que partiellement chargé, est réglé sur une position correspondante dans laquelle le compresseur (10) fait office de détendeur (3) avec effet d'étranglement variable sur le côté admission (3) du moteur auquel il transmet la puissance, remplaçant ainsi la commande traditionnelle des gaz.
