摘要： To provide a gas-liquid separator that can improve the separation performance of a liquid attached to a swirling flow generating ribbon and can reduce a required installation space. A gas-liquid separator includes the inlet pipe (21) and an inner pipe (22). The inlet pipe (21) receives a swirling flow generating ribbon (30), and includes an exhaust port (21a) through which a separated gas flows out and a drain port (21b) through which a separated liquid flows out. The outer diameter of the inner pipe (22) is smaller than the inner diameter of the inlet pipe (21). An end of the inner pipe is inserted into the exhaust port (21a) and is open at a location downstream of the swirling flow generating ribbon (30). A terminal end (31) of the swirling flow generating ribbon (30) includes a first terminal edge (32a) and a second terminal edge (32b). The first and second terminal edges (32a, 32b) connect a first terminal end point (31a), a second terminal end point (31b), and a middle terminal end point (31c). The first terminal end point (31a) is in one of radially outward ends and the second terminal end point (31b) is in the other of the radially outward ends. The middle terminal end point (31c) is closer to the side where the gas-liquid two-phase fluid flows in than the first and second terminal end points (31a, 31b) and is on an axial line (O).

摘要： An engine 1 includes: a urea water injector 40 which is provided in an exhaust pipe 30 of the engine 1 mounted on a vehicle and which injects and supplies urea water into the exhaust pipe 30; a selective reduction catalyst 34 which is provided in the exhaust pipe 30 on a downstream side of the urea water injector 40, and which reduces and purifies nitrogen oxide contained in an exhaust gas inside the exhaust pipe 30 by the urea water supplied from the urea water injector 40; and a low-pressure exhaust gas recirculation passage 45 which introduces the exhaust gas from the exhaust pipe 30 on an upstream side of the selective reduction catalyst 34 and recirculates the exhaust gas into an intake pipe 20 of the engine 1, in which when an exhaust gas recirculation valve 48 for opening and closing the low-pressure exhaust gas recirculation passage 45 is switched from a closed state to an open state, the urea water injector 40 stops injection and supply of the urea water.

摘要： The invention proposes a method for diagnosing an SCR catalyst of an internal combustion engine fitted with a low-pressure EGR loop removing exhaust gas downstream from the catalyst. The diagnostic criterion is a function of the difference between a measured concentration value of nitrogen oxides entering the catalyst and a modelled theoretical value. According to the invention, the flow of reductants in the catalyst is increased in order to cause ammonia leaks at the outlet of the catalyst; the concentration of nitrogen oxides and ammonia at the inlet of the catalyst is then measured and compared with a theoretical value of the concentration of nitrogen oxides at the inlet of the catalyst, modelled as a function of the operating point of the engine and the EGR rate. The catalyst is declared faulty when the difference between the measured concentration and the theoretical concentration exceeds a threshold.

摘要： L'invention propose un procédé de contrôle d'un moteur à allumage commandé du type suralimenté associé à un circuit de recirculation partielle des gaz d'échappement à l'admission, le moteur étant monté sur un véhicule automobile.
La principale caractéristique de ce procédé est que, en cas de lever de pied, on ferme d'abord la vanne du circuit EGR sans modifier la position du boîtier-papillon du moteur, et on active un alternateur du moteur pendant la durée de transfert des gaz recyclés depuis la vanne EGR jusqu'au moteur. Puis on désactive l'alternateur, on ferme presque complètement le boitier-papillon, et, dès que la pression d'admission du moteur devient inférieure à un seuil, on coupe l'injection de carburant.
L'utilisation du procédé est particulièrement avantageuse dans le cas où le circuit EGR est du type à basse pression, et/ou lorsque l'alternateur se présente sous la forme d'une machine électrique réversible, apte à ajuster la charge d'une batterie sans perte d'énergie.

摘要： During a rich spike control for an exhaust gas purification system for an internal combustion engine, a base air-fuel ratio AFb is decreased in a range where a combustion variation &Dgr;CC does not exceed a permissible limit &Dgr;CCL (S108). When the combustion variation &Dgr;CC exceeds the permissible limit &Dgr;CCL, the spike base air-fuel ratio AFbs is increased (S213). When the torque decrease amount &Dgr;TD is above the permissible value &Dgr;TDL, the spike base air-fuel ratio AFbs is decreased (S215). When the combustion variation &Dgr;CC is above the permissible limit &Dgr;CCL, and the torque decrease amount &Dgr;TD is above the permissible value &Dgr;TDL, the spike base air-fuel ratio AFbs is increased, and a fuel discharge time number EN is increased (S216).
