    摘要： In a cooling system (1) for a motor vehicle a quantity of relatively warm coolant stored within a thermally insulated tank (6) is used to heat the engine lubricating oil in an initial part of the warm-up phase of the engine (2), following a cold start. A conduit (102) which feeds the coolant leaving the engine (2) is connected to an inlet (601) of the thermally insulated tank (6) via a reduced cross-section (7) or a labyrinth pathway. Said conduit (102) is also connected to the inlet (300) of an electronically controlled distribution valve (3) having three outlets (301, 302, 303) respectively connected to the cooler of the lubricating oil of the engine (4), to the heater of the passenger compartment (8) and to the radiator (9) of the motor vehicle. In the initial phase of engine warm-up, the said valve (3) is in a closed condition, and the entire flow of coolant leaving the engine flows into the thermally insulated tank (6), moving the quantity of relatively warm liquid previously stored in said tank (6) to the engine lubricating oil cooler (4), where it contributes to a more rapid heating of the lubricating oil. In the subsequent phases of engine warm-up, the electronically controlled distribution valve (3) opens in succession the communication with the first outlet (301) connected to the cooler (4) of the engine lubricating oil, with the second outlet (302) connected to the heater of the passenger compartment (8) and with the third outlet (303) connected to the radiator (9) of the motor vehicle. When the engine (2) is switched-off, the thermally insulated tank (6) is again filled with warm coolant coming from the engine (2).

    摘要： The invention relates to a coolant distribution module for a coolant circuit which has at least one coolant duct to at least one heat source and at least one coolant duct to a heat sink, in particular for a power unit, in particular for an engine, in particular for an internal combustion engine, having a housing (10, 12) with at least three connectors (24, 28, 36, 42) which can be flowed through by coolant for fluid-conducting connection to the at least two coolant ducts, wherein a rotary slide (16) which can be rotated relative to the housing (10, 12) with control openings (60, 62, 64, 66, 68) is arranged in the housing (10, 12), which rotary slide (16) selectively establishes or interrupts fluid-conducting connections between the connectors (24, 28, 36, 42) of varying flow cross section by way of the control openings (60, 62, 64, 66, 68), wherein at least one sealing package (52, 54, 56, 58) is arranged between the housing (10, 12) and the rotary slide (16) at every connector (24, 28, 36, 42) in such a way that every sealing package (52, 54, 56, 58) forms a fluid-conducting duct between the rotary slide (16) and the housing (10, 12) and seals said fluid-conducting duct at a stop surface between the sealing package (52, 54, 56, 58) and the housing (10, 12) on one side and between the sealing package (52, 54, 56, 58) and the rotary slide (16) on the other side in a fluid-tight manner. Here, the rotary slide (16) is configured as a hollow cylinder with a cylinder wall (46), which hollow cylinder has a first end wall (58) at a first end in the axial direction and has a second end wall (50) at a second end which lies axially opposite said first end, wherein in each case at least one control opening (60, 62, 64, 66, 68) is configured in the cylinder wall (46) of the hollow cylinder, in the first end wall (58) and in the second end wall (50).

    摘要： The invention relates to an internal combustion engine with a combustion engine and a cooling system which comprises a coolant pump, a main cooler (30), a heating heat exchanger (28), a bypass (34) which bypasses the heating heat exchanger (28), coolant channels in the combustion engine, and a regulating device with an actuator for distributing a coolant in a controlled manner depending on at least one local coolant temperature. The invention is characterized in that when the actuator is actuated in one direction, the regulating device - allows a coolant flow through the combustion engine and the heating heat exchanger (28) and prevents a coolant flow through the bypass (34) and the main cooler (30) in a first position (72); - additionally allows a coolant flow through the bypass (34) in a second position (88); and - additionally allows a coolant flow through the main cooler (30) in a third position (96).

    摘要： [Problem] To obtain a thermostat device with which it is possible to dull the thermosensitivity of a thermo-element thermosensitive component to coolant water and better control the opening and closing of a main valve at a selected timing by means of an electrical heater. [Solution] A thermostat device (1) comprises: a piston (3); a cylinder container (4) which operates forward and reverse with respect to the piston and further comprises a flange valve which opens and closes a main flow path of coolant water; a thermal expansion body (W) which causes the cylinder container to operate forward and reverse upon the piston with a volumetric change commensurate with a temperature change within said cylinder container; and a thermo-element assembly body (10) which is disposed within the piston and further comprises a heat emitting element (H) which applies heat to the thermal expansion body by a supply of electricity. An insulating cover (20) is disposed which is formed to cover the exterior side portion of the cylinder container which faces the coolant water. Additionally, a resinous insulating material (21) and/or an atmosphere layer (22) are selectively disposed on the interior side of the insulating cover between said insulating cover and the exterior side face of the cylinder container.

    摘要： An internal combustion engine has a water-cooled intercooler cooling intake air turbocharged by a turbocharger. The intercooler has an HT intercooler into which HT cooling water passing through a cylinder block is introduced and an LT intercooler into which LT cooling water lower in temperature than the HT cooling water is introduced and the LT intercooler is arranged to abut against an intake downstream side of the HT intercooler. A target LT temperature is set to a high temperature-side target value in a case where a temperature of the HT cooling water flowing into the HT intercooler is lower than a target HT temperature correlated with warm-up completion and the target LT temperature is set to a low temperature-side target value in a case where the temperature of the HT cooling water is equal to or higher than the target HT temperature.
