Title (EN) INTERNAL-COMBUSTION ENGINE SUPERCHARGING DEVICE
(FR) DISPOSITIF DE SURALIMENTATION DE MOTEUR À COMBUSTION INTERNE

Abstract:
(EN) [Problem] In internal-combustion engine supercharging devices comprising a supercharging means provided with an air flow rate amplifier which performs supercharging in a driving flow, two driving flow supply means for supplying driving flows to the supercharging means, and a fluid control means for controlling the pressure and/or flow rate of the two driving flows, it is difficult to mix the two driving flows using an accurate mixing ratio by controlling the two driving flows using the respective fluid control means, and it is consequently difficult to perform appropriate supercharging of premixed gas such as fuel, which is the driving flow, and this gives rise to problems such as that, if the pressure differential between the two driving flows is large, backflow between the driving flows may occur. [Solution] In this internal-combustion engine supercharging device, by providing the fluid control means of the internal-combustion engine with a pump type mixer comprising positive displacement pumps provided in both fluid passages and a rotation control means interlocking the two pumps, it is possible for a mixing ratio obtained by controlling respective driving flow supply pressures and a supercharging pressure obtained by means of the rotation control performed by the rotation control means to be controlled accurately.
(FR) Le problème décrit par la présente invention réside en ce que dans des dispositifs de suralimentation de moteur à combustion interne comprenant un moyen de suralimentation doté d'un amplificateur de débit d'air qui effectue une suralimentation dans un flux d'entraînement, deux moyens d'alimentation de flux d'entraînement permettant de fournir des flux d'entraînement au moyen de suralimentation, et un moyen de commande de fluide permettant de commander la pression et/ou le débit des deux flux d'entraînement, il est difficile de mélanger les deux flux d'entraînement à l'aide d'un rapport de mélange précis en commandant les deux flux d'entraînement à l'aide du moyen de commande de fluide respectif, et il est par conséquent difficile de réaliser une suralimentation appropriée de gaz prémélangé tel que du carburant, qui est le flux d'entraînement, ce qui pose des problèmes tels que, lorsque la différence de pression entre les deux flux d'entraînement est grande, le reflux entre les flux d'entraînement peut se produire. La solution selon l’invention consiste en ce que, dans ce dispositif de suralimentation de moteur à combustion interne, en fournissant au moyen de commande de fluide du moteur à combustion interne un mélangeur de type à pompe comportant des pompes volumétriques prévues dans les deux passages de fluide et un moyen de commande de rotation reliant les deux pompes, un rapport de mélange obtenu en contrôlant les pressions d'alimentation de flux d'excitation respectives et une pression de suralimentation obtenue au moyen de la commande de rotation effectuée par le moyen de commande de rotation peut être commandé précisément.
(JA) 【課題】駆動流にて過給を行う空気流量増幅器を備えた過給手段と、前記過給手段に駆動流を供給する二つの駆動流供給手段と、前記二つの駆動流の圧力および/または流量を制御する流体制御手段と、から成る内燃機関の過給装置において、前記二つの駆動流を各々の前記流体制御手段にて制御するが、前記二つの駆動流を正確な混合比で混合することは困難であるので、駆動流である燃料等の適正な予混合気の過給が困難で、前記二つの駆動流の圧力差が大きい場合は駆動流同士の逆流等の問題点がある。 【解決手段】内燃機関の前記流体制御手段に、前記流体通路の両方に設けた容積型ポンプと前記二台のポンプを連動する回転制御手段で構成されるポンプ式ミキサを設け、各々の駆動流供給圧の制御による混合率と、前記回転制御手段の回転制御による過給圧を正確に制御できる内燃機関の過給装置である。
