摘要： A cooling apparatus for an engine, the cooling apparatus includes a main circuit (42), a warm-up circuit (43), a coolant passage (23, 24), a coolant pump (3), a pre-branching passage (41), a coolant temperature sensor (91) and an agitator (8). The warm-up circuit (43) allows a coolant to bypass the main circuit (42). The coolant passage (23, 24) is provided inside an engine body. The coolant pump (3) is configured to discharge the coolant toward the coolant passage (23, 24). The pre-branching passage (41) is communicated with an outlet side of the coolant passage (23, 24), and communicated with the main circuit (42) and the warm-up circuit (43). The coolant temperature sensor (91) is configured to detect a coolant temperature inside the pre-branching passage (41). The agitator (8) is disposed downstream of the coolant temperature sensor (91) when the coolant pump (3) is operating.

摘要： The invention concerns a method for cooling a motor vehicle engine, which consists in regulating the volume and the flow rate of a coolant in a hydraulic circuit (2) provided with a branch pipe (4) equipped with an actuator (14) electronically monitored and provided with means (9) forming a radiator. The method comprises a first step which consists in determining the temperature (T) of the coolant, a step which consists in comparing said temperature with a predetermined threshold temperature (T2) from which the engine is said to be hot , and, when the temperature (T) of the fluid is higher than the threshold temperature (T2), the flow rate in the radiator branch pipe (4) is regulated so as to maintain the temperature (T) of the coolant around a predetermined setpoint value (Tc). The invention is characterised in that the curve representing the opening (O) of the thermostat valve (4) based on the temperature (T) of the coolant exhibits hysteresis (h1, h2) around the setpoint temperature (Tc1, Tc2), so as to adjust the temperature (T) of the coolant to the setpoint temperature (Tc1, Tc2). The invention also concerns a device for cooling a motor vehicle engine.

摘要： A cooling circuit (1) for a vehicle internal combustion engine (2), having a first circuit branch (23) for cooling the cylinder head (3) of the engine (2); a second circuit branch (26) for cooling the engine block (4) of the engine (2) and connected in series to the outlet (25) of the first circuit branch (23); a feedback line (29) extending between the outlet (28) and the inlet (27) of the second circuit branch (26); and a valve (31) for controlling flow along the feedback line (29); the temperature of the coolant in the second circuit branch (26) is therefore higher than the temperature of the coolant in the first circuit branch (23), thus enabling the cylinder head (3) and the engine block (4) to be maintained at noticeably different operating temperatures.

摘要： The invention relates to a device for cooling a vehicle combustion engine control element comprising a principal coolant flow circuit which passes through the engine (1) and includes a circulation pump (3), a thermostatic valve (4) and a radiator (5). Said inventive device is characterised by the fact that a heat exchanger (14) that can cool the control element is mounted in a secondary circuit (13), downstream of the radiator, between said radiator (5) and the circulation pump (3). Furthermore, a restrictor (16) is mounted in the principal circuit in parallel with the exchanger (14). A branch (17) of the secondary circuit connects the exchanger (14) to the restrictor (16) and in this way the coolant can pass through said branch in either direction depending on whether the thermostatic valve (4) is open or closed.

摘要： Es wird ein Kühlsystem für Kraftfahrzeugantriebe beschrieben, welches einen Motorkühlkreis (10), in dem eine Motorkreis-Kühlmittelpumpe (20) das Kühlmittel wenigstens durch ein Motorkühlsystem (14) und einen Motorkreis-Wärmetauscher (16) pumpt, und welches wenigstens einen separaten Ladeluftkühlkreis (12), in dem eine Ladeluftkreis-Kühlmittelpumpe (26) das Kühlmittel durch wenigstens einen Ladeluftkühler (28) und einen Ladeluftkreis-Wärmetauscher (32) pumpt, aufweist. Die beiden Kühlkreise (10, 12) stehen mit einem gemeinsamen Flüssigkeitsbehälter in Verbindung.
Um bei einem Kühlsystem mit zwei separaten Kühlkreisen (10, 12) lediglich wenige Füllorte vorsehen zu müssen, wird vorgeschlagen, dass der Flüssigkeitsbehälter ein gemeinsamer Expansionsbehälter (36) ist und dass von jedem Kühlkreis (10, 12) wenigstens eine Entlüftungsleitung (50, 52) abzweigt, die in einen oberen Bereich des Expansionsbehälters (36) mündet.
