摘要： The invention relates to a device for purifying exhaust gas of a diesel engine comprising a first continuous regeneration type diesel particulate filter (122) arranged in the exhaust gas passage of an engine, a by-path (101) by-passing the exhaust gas passage on the upstream side of the first continuous regeneration type diesel particulate filter (122), a second continuous regeneration type diesel particulate filter (132) arranged in the by-path (101), a change-over valve (102) arranged in the exhaust gas passage between the by-path (101), an exhaust gas temperature-elevating means, an exhaust gas temperature region detecting means, and a control means (10) for controlling the exhaust gas temperature-elevating means and the change-over valve (102) based on the exhaust gas temperature region of the engine detected by the exhaust gas temperature region detecting means. When the exhaust gas temperature region of the engine detected by the exhaust gas temperature region detecting means is a temperature range lower than a predetermined temperature region, the control means (10) actuates the exhaust gas temperature-elevating means and controls the change-over valve (102) so that the exhaust gas passes through the second continuous regeneration type diesel particulate filter (132).

摘要： Die Erfindung bezieht sich auf ein Verfahren zur internen Abgasrückführung für mehrzylindrige Brennkraftmaschinen. Ein besonderes Problem für Dieselmotoren ist die Reduzierung der Stickoxide. Ein Weg zur Lösung dieses Problems stellt die Abgasrückführung dar. Gelöst wird die Abgasrückführung erfindungsgemäß zum einen dadurch, daß durch das Öffnen eines ersten Auslasses eines ersten Zylinders, welcher sich am Ende eines Expansionstakts befindet, eine Druckwelle entsteht, welche sich im gemeinsamen Abgaskrümmer fortpflanzt, daß während der Öffnung des ersten Auslasses ein zweiter Auslaß eines zweiten Zylinders, der sich in einem Ansaugtakt oder in einer frühen Phase eines Verdichtungstaktes befindet, über die für den eigentlichen Gaswechsel erforderliche Öffnungsdauer hinaus offen gehalten wird und daß durch die Druckwelle über den zweiten offengehaltenen Auslaß Abgas in den zweiten Zylinder zurückgeführt wird. Ein anderer Lösungsweg besteht darin, daß ein Einlaß eines an Expansionstakt befindlichen Zylinders gegen Ende der Expansion geöffnet wird, so daß durch die, zu diesem Zeitpunkt positive Druckdifferenz zwischen Zylinder und zugehörigem Einlaßkanal Abgas in diesen Einlaßkanal des Zylinders oder in eine davor liegende Leitung zurückströmt und daß die Rückführrate an Abgas durch Lage und Dauer der Öffnung des Einlasses gesteuert wird. Beide Lösungen erfordern nur relativ kleine bauliche Veränderungen an der Nockenwelle, zusätzliche Ventile werden nicht benötigt.

摘要： The present invention is directed to a valve actuation system for an internal combustion engine. The valve actuation system includes an intake valve actuation assembly for operating at least one intake valve in response to an intake cam. The valve actuation system further includes an exhaust valve actuation assembly operating at least one exhaust valve in response to at least one exhaust cam to produce at least one of a main exhaust event, an engine retarding event and an exhaust gas recirculation event. The exhaust valve actuation assembly is capable of operating in two modes. In the first operating mode, the at least one exhaust valve is operated to produce the main exhaust event. In the second operating mode, the at least one exhaust valve is operated to produce at least one of the main exhaust event, the engine retarding event and the exhaust gas recirculation event.

摘要： A method and apparatus for carrying out a variable timing exhaust gas recirculation is disclosed for use during both positive power and retarding operation of an internal combustion engine. Motion or energy is derived from an engine component and stored as potential energy. The stored energy (400) is selectively applied to a valve actuator (300) to carry out exhaust gas recirculation in an engine cylinder (40). The energy derived from engine may be stored and selectively applied to the valve actuator (300) with an electronically controlled trigger valve (400). The valve actuator (300) may be a slave piston (300) having an inner core (360) and an outer sleeve (370) capable of opening the exhaust valve (30) of the cylinder (40) in response to independent exhaust gas recirculation and compression release hydraulic systems.

摘要： A method wherein a number of cylinders (2, 3; 1, 4) are combined on a single exhaust manifold (8, 10) such that the pressure in the exhaust manifold (1e....4e) undergoes substantial time-dependent amplitude fluctuations, and an exhaust valve (6) of a cylinder (1) is opened during induction or filling thereof (i.e. adjacent to the bottom dead centre) so that, in a given range of engine speeds, a phase (28) of instantaneous low exhaust pressure in the exhaust manifold enables the inlet manifold (1a)/cylinder (1)/exhaust manifold (1e) to be scavenged while the inlet valve (5) and the exhaust valve (6) are both open. A phase (29) of instantaneous high exhaust pressure caused by another cylinder after the inlet valve (5) has closed and while the exhaust valve (6) is still open is used for post-filling the cylinder (1) with air (A) previously stored in the exhaust manifold (1e). The size of the turbine (T) is selected so that there is virtually no post-filling of the cylinder (1) with exhaust gases at engine speeds above said engine speed range.

摘要： Par un effet de centrifugation, l'air frais introduit dans la chambre de travail (1) du moteur est empêché de se mélanger aux gaz de combustion retenus intentionnellement dans celle-ci, d'un cycle à l'autre. Les moyens d'introduction du combustible sous pression (10) sont agencés de manière à injecter le combustible directement dans la zone centrale (G) de la chambre (1) où la concentration des gaz de combustion retenus et la température sont ainsi rendues maximales, ce qui permet de réduire le délai d'inflammation du combustible.

摘要： The invention relates to an internal combustion engine comprising at least one combustion chamber having an inlet valve and an outlet valve, the or each chamber being in communication with an inlet manifold when the inlet valve of the or each chamber is open, a piston reciprocable in the or each chamber to define a variable volume space therein, and means for controlling timing of the opening and closing of the inlet valve of the or each chamber so that opening occurs at a time when pressure in the or each chamber is lower than pressure in said inlet manifold, and the pressure differential across the inlet valve at said time is such that said opening of the inlet valve creates an in-flow to the or each chamber generating turbulence, at least some of which is present when combustion occurs in the or each chamber. Preferably, the inlet valve opens and closes twice during the induction and compression strokes, the first opening occurring at T.D.C. (A) and closing during the induction stroke (E), the second opening occurring at B.D.C. (B) or after it (G), and closing before the compression stroke finishes. Alternatively the outlet valve closing occurs after the end of the exhaust stroke and a single opening of the inlet valve occurs after the outlet valve closes, in order to produce said turbulence. A method of operating such an engine is also disclosed.
