摘要： A cooling system for an internal combustion engine of a motor-vehicle presenting a circuit (1) for a coolant of the engine. The circuit (1) comprises a thermally insulated tank (6) for the coolant of the engine, connected to an outer portion of the cooling circuit (101). The tank (6) is arranged in the circuit (1) to retain a defined quantity of coolant at a temperature above the ambient temperature when the engine (2) is inactive, and for causing this quantity of coolant to flow, at a temperature above the ambient temperature, into the cooling circuit of the engine (2), after a subsequent start of the engine (2), during an engine warm up stage. The circuit (1) also comprises an expansion vessel connected to the outer circuit portion (101) of the coolant of the engine (2). The expansion vessel has a thermally insulated body and constitutes the thermally insulated tank (6) for the engine coolant.

摘要： A motor-vehicle comprises one or more electrically-operated valves (101), arranged on the structure of the motor-vehicle in a lower position with respect to the windows (W, P), for providing a communication between the passenger compartment (10) of the motor-vehicle (100) and the external environment, and one or more electronic control units (ECU) programmed to activate a ventilation mode of the passenger compartment when the motor-vehicle is parked with the engine off, even with the driver outside the vehicle, said ventilation mode of the passenger compartment comprising controlling at least partial opening of one or more windows (W) and the opening of one or more of said valves (101) to generate a flow of natural air from the bottom upwards through the passenger compartment of the motor-vehicle.

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： A system for feeding air to an internal combustion engine of a motor-vehicle comprises a heat exchanger (IC) arranged along a duct (3) for feeding air, downstream of a supercharging compressor (SC), to cool a flow of air fed by the air compressor (SC), by means of a fluid that circulates in a cooling circuit of the engine. The system also comprises an evaporator (E2), interposed in the air feed duct (3) downstream of the heat exchanger (IC), to further cool the air flow by means of a coolant that circulates in an air conditioning circuit (A/C) of the motor-vehicle. The air conditioning (A/C) circuit of the motor-vehicle comprises a coolant compressor (CO) and an electronic controller (ECU) configured to control the activation of the coolant compressor (CO), depending on the request for air conditioning of the passenger compartment of the motor-vehicle, and the request for cooling the air fed to the engine. In particular the electronic controller (ECU) is configured to enable the coolant compressor (CO) to be activated only when the engine load is below a certain threshold.
