摘要： In an internal combustion engine provided with an electro-hydraulic system for variable actuation of the intake valves of the engine, each cylinder has two intake valves, which are associated with two intake conduits and are controlled by a single cam of a camshaft through a single hydraulic circuit. The communication of the hydraulic actuators of the two intake valves with a discharge channel is controlled by two electrically-actuated control valves, both of an on/off two-position type, arranged in series with each other along a hydraulic line for communication between the a pressure volume and the discharge channel.

摘要： System to cause a motor vehicle equipped with an automotive automated driving system to perform a Follow-Me low-speed manoeuvre under the control of a user terminal from the outside of the motor vehicle. The motor vehicle comprises automotive on-vehicle systems comprising a propulsion system, a braking system, a steering system, a sensory system; an automotive communications system to communicate with communications systems of user terminals; and an automotive electronic control unit configured to be connectable to the automotive on-vehicle systems and to the communications system, and to cooperate with the automotive on-vehicle systems to implement said automotive automated driving system. The user terminal comprises a digital image capture device and a communications system to communicate with automotive communications systems. The user terminal is programmed to communicate and cooperate with the electronic control unit of the motor vehicle to implement a Follow-Me functionality that allows a user from the outside of the motor vehicle and in possession of the user terminal to cause the motor vehicle to perform a Follow-Me low-speed manoeuvre under the control of the user terminal. The user terminal is further programmed to: set up a communication between the communications systems of the motor vehicle and of the user terminal, activate the digital image capture device so that the user can frame the motor vehicle, capture and process one or more digital images of the motor vehicle captured by the digital image capture device of the user terminal to identify the motor vehicle in the captured digital images and to compute a relative position of the user terminal relative to the identified motor vehicle based on the captured digital images, implement a surveillance device whose operating state is indicative of a continuous surveillance of the user in possession of the user terminal on the execution of the Follow-Me manoeuvre, and send to the electronic control unit of the motor vehicle Follow-Me data indicative of the relative position of the user terminal relative to the identified vehicle and the operating state of the surveillance device. The Electronic Control Unit is Programmed to: receive and process the Follow-Me data transmitted by the user terminal to determine the relative position of the user terminal relative to the motor vehicle and the operating state of the surveillance device, and control the automotive automated driving system the motor vehicle based on the Follow-Me data, so as to cause the motor vehicle to perform a Follow-Me low-speed manoeuvre under the control of the user terminal to follow the movements of the user in possession of the user terminal as long as the operating state of the surveillance device is such as to indicate a continuous surveillance of the user in possession of the user terminal on the execution of the Follow-Me low-speed manoeuvre, and to interrupt the Follow-Me low-speed manoeuvre when the operating state of the surveillance device is such as to indicate an interruption of the surveillance of the user in possession of the user terminal on the execution of the Follow-Me manoeuvre.

摘要： A system for feeding air to an engine of a vehicle includes a heat exchanger arranged along a duct for feeding air, downstream of a supercharging compressor, to cool a flow of air fed by the air compressor, by a fluid that circulates in an engine cooling circuit. The system also includes an evaporator, interposed in the duct downstream of the heat exchanger, to further cool the air flow by a coolant that circulates in an air conditioning circuit of the vehicle. The air conditioning circuit includes a coolant compressor and a controller for controlling activation of the coolant compressor, depending on a request for air conditioning of a passenger compartment of the vehicle, and a request for cooling the air fed to the engine. The electronic controller is configured to enable the coolant compressor to be activated only when the engine load is below a certain threshold.

摘要： In a motor-vehicle seat a padding body of a cushion and/or backrest has a passage for air coming from an air conditioning system of the motor-vehicle. This passage includes a closed cavity defined between a lowered surface formed in an outer surface of the padding body and the seat cover. At least part of the closed cavity is separated from the cover through a layer of a material substantially impervious to air, configured to exchange heat by thermal conduction, through the cover with a body of an occupant.

摘要： A hatchback door includes a load-bearing inner panel made of composite plastic material, a plastic top outer panel glued on a top portion of the inner panel, and a plastic bottom outer panel glued on a bottom portion of the inner panel. The top panel includes a first layer of transparent plastic material and a second layer of opaque plastic material or opaque paint. The opaque layer covers only some of the transparent layer such that the top panel is transparent in a central part overlying a rear-window opening of the inner panel and in its peripheral portions that function as transparent elements for two lateral sets of lights and a third top set of lights. The light sets are without a front transparent element and are connected to a rear side of the top panel. The transparent peripheral portions constitute the front transparent elements of the light sets.

摘要： In a vehicle cooling system, a quantity of warm coolant stored within a thermally insulated tank is used to heat engine lubricating oil in an engine warm-up phase following a cold start. A conduit feeding coolant leaving the engine is connected to an inlet of the tank via a reduced cross-section or a labyrinth pathway. The conduit is connected to an inlet of an electronically controlled distribution valve having three outlets connected to the oil cooler, a passenger compartment heater, and a radiator. In an initial part of the warm-up phase, the valve is closed, and the entire flow of coolant leaving the engine flows into the tank, moving the quantity of warm coolant previously stored in the tank to the oil cooler, where it contributes to more rapid heating of the lubricating oil. When the engine is switched-off, the tank is again filled with warm coolant from the engine.
