摘要： The invention concerns a device and method for cooling and preheating, especially of transmission fluid, of an internal combustion engine, with an equalization tank, with at least one radiator, which can be connected by means of an engine thermostat when a predetermined temperature is reached in the cooling loop, and with a water/oil heat exchanger. It is prescribed according to the invention that the forward stream (1) of a single water/oil heat exchanger (5) be branched off in the heating phase by means of a valve unit (3) essentially from the main cooling loop (12) of the internal combustion engine (17) and that its forward stream (1) in the cooling phase be taken by means of the same valve unit (3) essentially in the coolant side stream (13) from the low-temperature region (14) of the radiator (4) or a separate low-temperature cooler (14a) connected in the side stream after radiator (4, 4a). The method proposes that the forward stream (1) of the water/oil heat exchanger (5) be taken in the heating phase essentially from the main coolant stream (12) not flowing through the radiator (4), that switching to cooling operation occur at a temperature lying somewhat below the switch point of the engine main thermostat (9) and the forward stream (1) of the water/oil heat exchanger (5) in cooling operation be branched off essentially from the low-temperature region (14) of radiator (4), or from a low-temperature cooler (14a) additionally connected in the side stream after radiator (4, 4a).

摘要： In order to control the temperature of the transmission oil of a motor vehicle driven by a liquid-cooled engine, a coolant/transmission oil heat exchanger is provided. The coolant stream supplied to the heat exchanger is miscible in a thermostatic valve from recooled and non-recooled coolant in order to achieve a desired temperature. Preferably the thermostatic valve is controlled by the temperature of the transmission oil, but it is also possible to have two expanding material elements as control pistons of the thermostatic valve, with one control piston being provided in the oil chamber of the thermostatic valve and the other control piston being provided in the coolant mixing chamber of the thermostatic valve. It is also possible, for purposes of precontrol, to electrically heat at least one of the control pistons.

摘要： A cooling circuit includes a valve device (1, 1', 1") for a separate heat exchanger (42), especially of an internal combustion engine (48). To achieve a combined pressure limitation and pipe or hose break valve, a valve body (6, 35, 50), upon reaching a coolant throughput for maximum heat transfer in heat exchangers (42) located downstream, is actuated as a function of delivery pressure into an engaged position with a valve seat (5, 51). A throttle passage (7, 36, 52) maintains a coolant throughput that corresponds to maximum heat transfer. In the event of a pipe or hose break, the valve body (6, 35, 50) serving as part of a pipe or hose break is locked in a closed position.

摘要： A coolant temperature control system for an internal-combustion engine in a motor vehicle having an electrically heatable thermostatic valve whose method of operation can be shifted by electrical heating in the radiator operation direction. Control devices are provided for recognizing a defect of another system in the motor vehicle which controls the coolant flow. When a defect of this other system is recognized, the thermostatic valve is heated. Particularly when a defect is recognized, the heating of the thermostatic valve is controlled such that the coolant temperature is maintained below a preset coolant temperature threshold. Preferably, the recognition of a defect is carried out by means logically monitoring output signals of the other system.

摘要： In a device for control of a motor vehicle engine operating at idle with two rows of cylinders, having a catalytic converter with an oxygen sensor associated with each, during operation of the engine at idle the injectors of one of the two rows of cylinders are alternately switched off. This switching of the injector shut-off from one row of cylinders to the other row of cylinders always takes place when the temperature of the catalytic converter associated with the row of cylinders that has just been shut-off falls below a predetermined temperature limit. Alternatively, in a device for control of a motor vehicle engine operating at idle with only one catalytic converter and only one oxygen sensor, during operation of the engine at idle the injectors are sequentially shut-off according to a predetermined program as a function of the engine firing order. This sequential injector shut-off is suspended at least for a predetermined period of time when the temperature of the catalytic converter falls below a predetermined temperature limit.

摘要： In the case of a cooling system for an internal-combustion engine of a motor vehicle comprising a radiator and a thermostatic valve by means of which the temperature of the coolant can be controlled in a warm-up operation, a mixed operation and a radiator operation. The thermostatic valve containing an expansion element can be electrically heated for reducing the coolant temperature, the expansion element being designed such that the coolant temperature is controlled without any heating of the expansion element in the warm-up operation and/or the mixed operation to an upper operating limit temperature. In addition, a temperature switch is provided which, as a function of the coolant temperature detected at the or near the radiator outlet, releases the heating of the expansion element as required in order to shift the method of operation of the cooling system toward the radiator operation.

摘要： A cooling device is provided for a motor vehicle liquid-cooled internal combustion engine with a radiator connected to the supply and return lines of the engine. The radiator has a filling opening closable by a cap. A temperature-controlled thermostatic valve, via which the coolant is sent completely or partially either through the radiator or through a bypass between the supply and return lines to bypass the radiator, is controllable by electrical heating. An electrical switch is mounted on the filling opening such that upon actuation the thermostatic valve is electrically heated, so that the coolant passes at least partially through the radiator.

摘要： A cooling system for an internal-combustion engine of a motor vehicle having a radiator and a thermostatic valve by which the temperature of the coolant can be controlled in a warm-up operation, a mixed operation and a radiator operation. The thermostatic valve contains an expansion element which can be electrically heated for reducing the coolant temperature, the expansion element being designed such that the coolant temperature is set without heating the expansion element in the warm-up operation and/or in the mixed operation to an upper working limit temperature. A control unit is provided which, as a function of sensed operating and/or environmental quantities of the internal-combustion engine, activates the heating of the expansion element, as required, in order to shift the operating mode of the cooling system from the warm-up operation or from the mixed operation of the upper working limit temperature in the direction of the mixed operation or radiator operation of a coolant temperature which is lower with respect to the upper working limit temperature.
