摘要:
Verfahren und Anordnung zur Optimierung der motorischen Verfügbarkeit einer mittels Kühlkreislauf gekühlten Elektromobilitätskomponente die Antriebsleistung in einem Fahrzeug einspeist. Es ist vorgesehen, dass eine Steuer- und Regeleinheit aus einer zukünftigen Fahrstrecke Spitzenbelastungen des Kühlkreislaufs ermittelt und dass fahrstreckenbezogen zeitlich vor diesen Spitzenbelastungen des Kühlkreislaufs vorausschauend mittels wenigstens eines im Kühlkreislauf vorgesehenen Wärmetauschers zusätzliche Kühlleistung in das System eingespeist wird derart, dass die durch die Elektromobilitätskomponente zur Verfügung gestellte Antriebsleistung optimiert wird und die Elektromobilitätskomponente im Durchlaufen und nach dem Durchlaufen der Fahrstrecke eine zulässige Grenztemperatur nicht überschreitet.
摘要:
To provide a control device for an internal combustion engine with which decreases in torque and output can be prevented by appropriately controlling an opening and closing operation of an on-off valve provided midway along a water drainage line. This control device for an internal combustion engine includes an intake passage (4), an exhaust passage (5), an intercooler (10), a catalyst (18), a water drainage line (28), an on-off valve (29), a detection means (20), and an on-off valve control unit (30). The intake passage (4) has one end connected to an intake side of an internal combustion engine (1). The exhaust passage (5) has one end connected to an exhaust side of the internal combustion engine (1). The intercooler (10) is disposed in the intake passage (4). The catalyst (18) is provided in the exhaust passage (5). The water drainage line (28) has one end connected to a portion of the intake passage (4) downstream of the intercooler (10), has another end connected to a portion of the exhaust passage (5) upstream of the catalyst (18), and allows condensation water condensed by the intercooler (10) to be discharged therethrough to the exhaust passage (5). The on-off valve (29) is provided midway along the water drainage line (28). The detection means (20) is provided in at least one of the intake passage (4) and the exhaust passage (5) and detects at least one of a state of intake air and a state of exhaust. The on-off valve control unit (30) performs opening and closing control of the on-off valve (29) in accordance with output of the detection means (20).

摘要:
A housing element (202) associated with an engine system (100) is provided. The housing element (202) includes an inlet portion (206) defined on a first sidewall (204) of the housing element (202). The housing element (202) also includes an outlet portion (212) defined on a second sidewall (210) of the housing element (202). The housing element (202) further includes an opening (216) defined on a third sidewall (214) of the housing element (202). The third sidewall (214) is adjacent and generally perpendicular to the second sidewall (214). The housing element (202) further includes a plate (400) including a first section (402) and a second section (408). The first section (402) of the plate (400) is fixedly coupled to an inner side (220) of a bottom wall (222) of the housing element (202).
摘要:
The present disclosure relates to a cooling system (100) for an internal combustion engine (14). The cooling system (100) comprises a high-temperature cooling circuit piping (44, 46, 48) including high-temperature cooling circuit connection ports (49) and a low-temperature cooling circuit piping (64, 66) including low-temperature cooling circuit connection ports (67). The cooling system (100) further comprises a two-stage charge air cooler unit (50; 504, 506) including a first cooling stage (42) with first cooling stage connection ports (43) and a second cooling stage (60) with second cooling stage connection ports (61). The first cooling stage (42) provides a first heat transfer performance and the second cooling stage (60) provides a second heat transfer performance different from the first heat transfer performance. The two-stage charge air cooler unit (50) includes a first mounting position and a second mounting position. In the first mounting position the first cooling stage (50) is connected to the high-temperature cooling circuit connection ports (49) via the first cooling stage connection ports (43) and the second cooling stage (60) is connected to the low-temperature cooling circuit connection ports (67) via the second cooling stage connection ports (61). In the second mounting position the first cooling stage (42) is connected to the low-temperature cooling circuit connection ports (67) via the first cooling stage connection ports (43), and the second cooling stage (60) is connected to the high-temperature cooling circuit connection ports (49) via the second cooling stage connection ports (61).
摘要:
Method for detecting the failure of a charge air cooler (9) installed in an air intake circuit (3) of a motor vehicle internal combustion engine (1), said circuit (3) comprising a compressor (7) upstream of the cooler (9), said method being performed continuously in successive iterations and comprising a step of determining the cooled charge air temperature (Tsras) between the cooler (9) and the engine (1), characterized in that it further comprises: - a step of calculating the rate of variation with respect to time (dTsras/dt) of said cooled charge air temperature (Tsras); - a step of comparing said rate (dTsras/dt) with at least one fist positive threshold (S1); and, - a step of establishing a diagnosis of whether the cooler (9) is operating correctly or incorrectly on the basis of this comparison.
