摘要： This lubrication system for a differential of a driven axle on an automotive vehicle includes a sump in which is located a crown wheel driven by a pinion, the crown wheel being fast in rotation with a carrier, and a main lubricant tank having an inlet port and at least one outlet port. Rotation of the crown wheel causes lubricant to be transferred from the sump to the main tank via the inlet port, and the outlet port allows the lubricant to pass from the main tank to the sump. The lubrication system includes an auxiliary lubricant tank located in the sump, adapted to be filled in with lubricant by rotation of the crown wheel, and an arrangement to convey lubricant from auxiliary tank to a lubricant needing portion of the differential.

摘要： An internal combustion engine includes a plurality of cylinders, an air intake line and an exhaust line collecting exhaust gas. The engine also includes an EGR line for rerouting a part of the exhaust gas from the exhaust line towards the air intake line and at least a first turbocharger comprising a first turbine driven by the exhaust gas flowing towards the atmosphere, linked to a first compressor located on the air intake line. The engine further includes a variable geometry EGR turbine located on the EGR line, driven by the EGR gas flowing in the EGR line. Thus, thanks to the pressure reduction occurring in the turbine, the EGR gas temperature is lowered, and less cooling power from the engine cooling system is required to cool down the EGR.

摘要： A valve actuation mechanism includes rockers moved by a camshaft, each rocker being adapted to exert a valve opening force on at least a portion of a valve opening actuator of each cylinder, via an activation piston, housed in a bore of the rocker and movable with respect to the rocker under action of a fluid pressure raise in a chamber fluidly linked to the bore, from a first position to a second position, in which a cam follower of the rocker reads at least one auxiliary cam sector of a cam of the camshaft so as to perform an engine operating function. Each rocker includes a reset valve adapted to reduce fluid pressure in the chamber. The valve actuation mechanism includes, for each rocker, a reset cam profile adapted to open the reset valve when the activation piston has to be moved from its second position to its first position, and each reset valve includes a cam follower adapted to drive the reset valve as a function of the movement of the reset profile.

摘要： A dual drive arrangement has three way power split device such as an epicyclic gearing system converting input rotation from a gearbox or from an electric motor into an output rotation driving a hydraulic pump. A method for controlling the dual drive arrangement driving a hydraulic pump includes setting a minimal flow value to the hydraulic pump, sensing the vehicle speed, processing the sensed vehicle speed, where the processing includes comparing the sensed vehicle speed with a reference speed value to thereby determine whether the vehicle operates in a first operational mode I where the speed vehicle is too low to drive the hydraulic pump up to the minimal flow or in a second operational mode II where speed vehicle where the speed vehicle is sufficient to meet at least the minimal flow value, and controlling the operation of the epicyclic gear so that the electric source drives the hydraulic pump when the vehicle runs under the first operational mode I and at least the gearbox drives the hydraulic pump when the vehicle runs under the second operational mode II.

摘要： A method is provided for controlling a power supply system of an automotive vehicle that includes at least one battery and at least one associated battery managing unit adapted to monitor the state of charge of the battery. During an off state of the vehicle, the state of charge level of each battery is monitored by the battery managing unit. If the state of charge monitored reaches a low state of charge threshold, an on-board communication device adapted to emit a critical state of charge level alarm to be received by an off-board reception device is activated. The power supply system includes a battery managing unit per battery and an alarm to emit a critical state of charge level alarm.
