摘要:
A trapped burned gas fraction is controlled in a two-stroke cycle opposed-piston engine with uniflow scavenging by adjusting an external EGR setpoint in real time. The adjusted setpoint is used to control EGR flow in the engine's air handling system.

Die vorliegende Erfindung betrifft eine aufgeladene Brennkraftmaschine (2), vorzugsweise eines Fahrzeugs (1), mit einem Kältekreis (9) sowie einer Frischluftanlage (3) zur Versorgung der Brennkraftmaschine (2) mit Frischluft aufweist. Eine erhöhte Sicherheit des Kühlsystems (8) ergibt sich dadurch, dass ein Zwischenkreis (18) vorgesehen ist, in dem ein Zwischenmedium zirkuliert und in dem ein erster Verdampfer (15) des Kältekreises (9) sowie ein erster Ladeluftkühler (17) der Frischluftanlage (3) eingebunden sind, wobei der Zwischenkreis (18) fluidisch von der Frischluftanlage (3) sowie von dem Kältekreis (9) getrennt ist. Eine erhöhte Effizienz des Kühlsystems (8) ergibt sich ferner dadurch, dass ein Kältekreiskompressor (10) zum Antreiben eines Kältemittels im Kältekreis (9) in Schubphasen eines zugehörigen Fahrzeugs (1) durch eine Schubleistung des Fahrzeugs angetrieben wird. Die Erfindung betrifft des Weiteren ein solches Fahrzeug (1).
摘要:
The present invention relates to a crosswalk illumination device and a crosswalk illumination method that illuminate a crosswalk so that a driver can easily discern a pedestrian, and more particularly, to an illumination device and an illumination method that divide an area of a crosswalk into multiple areas so as to sequentially illuminate each of the areas of the divided cross - walk in the direction in which the pedestrian walks, starting from the area closest to the pedestrian. Also, the present invention relates to an illumination device that is configured to include a first light-emitting unit that performs illumination according to a movement of the pedestrian, and a second light-emitting unit that illuminates the road all the time. According to the illumination device and the illumination method of the present invention, an LED that is installed on each surface of an illumination substrate illuminates each of the virtually divided areas of the crosswalk so that the present invention can be applied to a crosswalk across many lanes at a reduced installation cost, and illumination can be prevented from being concentrated on a portion of the areas of the cross-walk. Also, according to the illumination device and the illumination method of the present invention, the area of the crosswalk is divided into the multiple areas so as to sequentially illuminate each of the areas of the divided crosswalk in the direction in which the pedestrian walks, starting from the area closest to the pedestrian. Thus, energy efficiency can be improved and the driver can easily discern a pedestrian walking on a crosswalk.
摘要:
Die Erfindung betrifft eine Ladeluftkühleranordnung (1) für ein Kraftfahrzeug, vorzugsweise ein Nutzfahrzeug. Die Ladeluftkühleranordnung (1) umfasst einen Ladeluftkühler (2). Die Ladeluftkühleranordnung (1) zeichnet sich insbesondere dadurch aus, dass eine zumindest abschnittsweise flexible Verbindungskonstruktion (3) von der Auslassseite des Ladeluftkühlers (2) abzweigt und auf der Einlassseite des Ladeluftkühlers (2) mündet, um Kondensat auf der Einlassseite des Ladeluftkühlers (2) abzusaugen, und der Ladeluftkühler (2) eine Montageeinrichtung (5) zum Verschwenken des Ladeluftkühlers (2) umfasst, so dass der Ladeluftkühler vorzugsweise verschwenkbar ist, ohne den Ladeluftkreis zu öffnen.
摘要:
A two-stroke cycle, turbo-driven, opposed-piston engine with one or more ported cylinders and uniflow scavenging has no supercharger. The engine includes a high pressure EGR loop and a pump in the EGR loop to boost the pressure of the recirculated exhaust products.

The invention relates to an air supply system (4) for supplying the combustion chambers (3) of a supercharged internal combustion engine (1) with fresh air, the system comprising a housing (13), through which a fresh air path (14) runs and which has a lateral introduction opening (18), and comprising a charge-air cooler (12) which is introduced into the housing (13) through the introduction opening (18) in an introduction direction (19) such that the fresh air path (14) runs through the charge-air cooler (12). An outer end region (20) of the charge-air cooler (12) closes the introduction opening (18). To achieve a simplified assembly, the outer region (20) of the charge-air cooler (12) is locked with the housing (13).
摘要:
A plurality of upper fins (3) and a plurality of lower fins (4) are each provided in an EGR passage (2) so as to be adjacent to each other across a predetermined space (5A to 5C, 6A to 6C) in a direction perpendicular to an exhaust-gas flow direction. The upper fins (3) and the lower fins (4) are gradually narrowed in width toward their respective projection directions, so that both sides thereof in their width direction have inclined surfaces. A tilt angle (β) of the inclined surfaces of the lower fins (4) is made larger than a tilt angle (α) of the inclined surfaces of the upper fins (3).

The present invention relates to a fresh-air system (1) for supplying combustion chambers of a supercharged internal combustion engine with fresh air, comprising a housing (2), through which a fresh-air path (3) is led, an intercooler (4), which is arranged in the housing (2) in such a way that the fresh-air path (3) leads through the intercooler (4), and at least one bypass seal (6) extending perpendicularly to the fresh-air path (3), which bypass seal is arranged between the housing (2) and the intercooler (4) and hinders bypassing of the intercooler (4) on the air side. Improved sealing results if the particular bypass seal (6) comprises a seal support (8), which bears at least one sealing body (9, 10) and comprises a guide lug (11), wherein the housing (2) comprises a guide groove (12), which extends perpendicularly to the fresh-air path (3) and is open to the fresh-air path (3), into which guide groove the guide lug (11) is inserted in an insertion direction (13), wherein the guide lug (11) is arranged in such a way that the guide lug can be moved in the guide groove (12) in the insertion direction (13).
