Title
(EN) DUAL-ROTOR ENGINE AND REGULATION METHOD FOR OPERATING PARAMETER THEREOF
(FR) MOTEUR À DEUX ROTORS ET SON PROCÉDÉ DE RÉGULATION POUR PARAMÈTRE DE FONCTIONNEMENT
(ZH) 一种双转子发动机及其运行参数的调控方法
Abstract
(EN) A dual-rotor engine, comprising stators and rotors (8), and comprising two rotors (8) connected in series, i.e., a first rotor and a second rotor. The two rotors are both 8-shaped. An included angle between 8-shaped major axes of the two rotors is 180 degrees. Each stator is internally provided with three petal-shaped cavities enclosed by three arc-shaped side walls. The rotors (8) are located in the three petal-shaped cavities inside the stator. Arcs of 8-shaped heads match circular arcs constituting the three petal-shaped cavities. The dual-rotor engine has two stators, i.e., a first stator (201) and a second stator (202). Combustion chambers are added on side walls of the rotors of the dual-rotor engine. When the head of the 8-shaped rotor (8) is located in one of the three petal-shaped cavities, in addition to the combustion space provided on the interval between the arc-shaped side wall of the rotor and an arc-shaped inner wall of the cavity, the combustion spaces of the combustion chambers are further additionally provided, so that oil and gas are mixed more uniformly. Also disclosed are a regulation method for an operating parameter of the dual-rotor engine, and an operating method for the dual-rotor engine.
(FR) La présente invention concerne un moteur à deux rotors comprenant des stators et des rotors (8) et comprenant deux rotors (8) raccordés en série, c'est-à-dire un premier rotor et un second rotor. Les deux rotors sont tous les deux en forme de 8. Un angle inclus entre les axes principaux en forme de 8 des deux rotors est de 180 degrés. Chaque stator est pourvu en son sein de trois cavités en forme de pétale entourées par trois parois latérales en forme d'arc. Les rotors (8) sont situés dans les trois cavités en forme de pétale à l'intérieur du stator. Des arcs de têtes en forme de 8 correspondent à des arcs de cercle constituant les trois cavités en forme de pétale. Le moteur à deux rotors comprend deux stators, à savoir un premier stator (201) et un second stator (202). Des chambres de combustion sont ajoutées sur les parois latérales des rotors du moteur à deux rotors. Lorsque la tête du rotor en forme de 8 (8) est située dans l'une des trois cavités en forme de pétale, en plus de l'espace de combustion prévu sur l'intervalle entre la paroi latérale en forme d'arc du rotor et une paroi interne en forme d'arc de la cavité, les espaces de combustion des chambres de combustion sont en outre prévus, de sorte que l'huile et le gaz sont mélangés de manière plus uniforme. La présente invention concerne également un procédé de régulation d'un paramètre de fonctionnement du moteur à deux rotors, et un procédé de fonctionnement du moteur à deux rotors.
(ZH) 一种双转子发动机,包括定子和转子(8),该双转子发动机包括2个串联的转子(8),分别为第一转子和第二转子,2个转子均为"8"字形,2个转子的"8"字形的长轴的夹角为180度,定子内部具有三段弧形侧壁围成的三瓣形空腔,转子(8)位于定子内部的三瓣形空腔中,"8"字的头部的弧与构成三瓣形空腔的圆弧相适配;该双转子发动机有2个定子,分别为第一定子(201)和第二定子(202)。该双转子发动机在转子的侧壁上增加了燃烧室,当"8"字形转子(8)的头部位于三瓣形空腔中的一个空腔时,除了转子的弧形侧壁和该空腔的弧形内壁间距提供燃烧空间,还额外有燃烧室的燃烧空间,使油气混合更加均匀。还公开了一种双转子发动机运行参数的调控方法及一种双转子发动机的运行方法。
