摘要： The invention describes a control circuit (10) for an LED external lighting unit (2) of a vehicle (1), said lighting unit (2) comprising at least an LED source (L1, L2) and a passive heatsink (3). The control circuit (10) comprises: - a temperature sensor (11) adapted to provide a first output signal (s_t) carrying information about the operating temperature of the LED source (L1, L2) and/or of the passive heatsink (3); - a first output node (NO_1) operatively connectable to an optical and/or acoustic warning device (6) and adapted to provide thereto a first control signal (s_a), depending upon the first output signal (s_t), adapted to produce an alarm warning through said warning device (6) when said temperature is higher than a first threshold value (T1); - a driver unit (12) of the LED source (L1, L2) comprising a first input node (NI_1) adapted to receive a second control signal (s_c), depending upon the speed of the vehicle (1) and the first output signal (s_t), the driver unit (12) being adapted to output an LED source driving signal (s_d), said driving signal being a relatively high-power signal or a relatively low-power signal according to the second control signal (s_c).

摘要： A combined ignition and fuel supply system for an internal combustion engine is described. The system comprises an ignition unit and a blending/dosing device (10) comprising a valve and equipped with an entrance duct (12) for the combustive agent, usually air, an entrance duct (14) for the fuel and an exit duct (16) for the fuel-combustive agent blend. The exit duct (16) is hydraulically connected to an aspiration manifold (18) which introduces the fuel-combustive agent blend into the cylinder (20) of the engine. Downstream of the valve of the blending/dosing device (10) and upstream of the cylinder (20), there is at least one pressure sensor (22) used to identify the pressure value of the fuel-combustive agent blend inside the aspiration manifold (18), in order to optimise fuel consumption and/or improve performance, varying the advance in relation to the pressure value in the aspiration manifold (18) and the engine revs.
