Abstract: A diesel engine system comprises a particulate filter interposed in an exhaust line and a plurality of fuel injectors associated with an engine. When a quantity of particulate accumulated within said filter is estimated to be greater than a threshold, a control mode of the injectors is activated causing an automatic regeneration of the filter, by increasing a temperature of exhaust gases fed to the filter sufficient for burning the particulate within the filter. A statistical model is applied which estimates the quantity of particulate accumulated in the filter per time unit The estimation of the particulate accumulated in the filter is corrected after each regeneration of the filter, on a basis of a comparison between the real variation of said temperature during the regeneration as detected by a sensor and a stored reference variation of said temperature previously detected empirically during a regeneration with the filter being empty.

Abstract: A cylinder head for an internal-combustion engine includes, for each cylinder of the engine, at least one intake duct extending from an inlet located at a lateral face of the head down to an outlet cylindrical mouth and an intake valve associated with each intake duct. The surface of the intake duct has a longitudinal projection for deflecting the flow of air that flows through the intake duct. The projection is configured to provide a deflection of the air flow towards the two sides of the valve stem, so as to substantially reduce the quantity of air that hits the valve stem directly. The projection extends down to the outlet cylindrical mouth, so as to hinder a flow of air through an angular sector of the cross-sectional area of the outlet mouth which angular sector faces towards the lateral face of the cylinder head.

Abstract: An engine includes a crankcase; an oil sump; at least one balancing shaft mounted in a balancing tunnel of the crankcase, which includes first and second end portions and a central portion extending between the end portions; and a blow-by gas recirculation system having an inlet channel communicating with the oil sump, an outlet channel communicating with an intake manifold, a centrifugal separator arranged between said inlet and outlet channels, and a drainage channel opening into the oil sump for discharging separated liquid. The inlet channel communicates with said first end portion, and said centrifugal separator is housed in said second end portion and is driven in rotation by said balancing shaft. The outlet channel communicates with a gas outlet of said centrifugal separator, whereby, during operation, blow-by gas flows successively through the central portion and the centrifugal separator in a path from the inlet to the outlet channel.

Abstract: A lever device for actuating the parking brake of a motor-vehicle includes a lever structure with a base portion tiltably mounted on a supporting bracket. The mounting includes a first transverse axis, a second transverse axis, a third transverse axis and a fourth transverse axis. When the lever structure is in its completely lowered position, the third and fourth transverse axes are each lower than that of the first and second transverse axes, respectively. In the lowered position, two theoretical planes containing the first and third transverse axes and the second and fourth transverse axes, respectively, intersect along a theoretical axis of instantaneous rotation of the lever structure, which is located above the first and second transverse axes. When the lever structure moves to its completely raised position, the lever arm and its end handgrip displace according to a substantially elliptical, and substantially vertically oriented, path, respectively.

The gear shift system includes gear shift devices rotationally integral with the steering wheel and an electronic control device. Each of the gear shift devices is operable by a driver of the motor vehicle to carry out at least one respective gear shift function associated with the respective gear shift device. The electronic control unit is configured to receive a magnitude indicative of a current steering wheel angle, determine, on the basis of the received magnitude, whether the current steering wheel angle satisfies predefined conditions, and, if it determines that the current steering wheel angle satisfies the predefined conditions, reconfigure the gear shift functions associated with the gear shift devices.

Abstract: A supporting and braking assembly for a motor vehicle wheel has a supporting member, defined by a single piece adapted to be coupled to a suspension of the motor vehicle and provided with a central portion coupled to a rotating hub by means of a bearing. The supporting member is also provided with two arms which extend in cantilevered manner from the central portion in essentially radial directions and support respective studs, to which a floating caliper is slidingly coupled. The caliper is arranged straddling a brake disc, fixed and coaxial with respect to the hub, and supports two brake pads arranged on opposite sides of the brake disc. At least one of the studs is sized so as to transfer the tangential loads caused by braking from the caliper directly onto the corresponding arm.

Abstract: A support and retention assembly for a portable electronic device has a support member with a front surface which defines a rest surface. The support member is connected to a structure of a dashboard so as to able to be moved between a retracted position and an extended position, in which it is locked by means of releasable locking devices. The assembly is provided with a rest element which projects from the front surface at a lower end of the support member and a clamp which is arranged over the rest element and may rotate upwards about a horizontal axis starting from a stowed position, in which at least part of the clamp is housed in a seat made in the front surface.

Abstract: A fuel tank for a motor-vehicle includes a vent conduit connected to a canister arranged outside of the tank for absorbing fuel vapors. The vent conduit has a portion arranged inside the tank with an intermediate portion located at a lowermost position, which creates a zone in which liquid fuel tends to stagnate, which is originated from condensation of the vapors inside the vent conduit. The tank further includes a conduit for draining the liquid fuel originated from condensation of vapors present within the vent conduit. The draining conduit extends downwardly starting from the zone and ends with a closed end portion acting as accumulator and evaporator of the fuel. The closed end portion is arranged at an area which can reach a temperature sufficient for causing evaporation of the condensed fuel and elimination thereof by a flow in an opposite direction through the draining conduit and then through the vent conduit towards the canister.
