An intake manifold () of comburent air is provided for an internal combustion engine () with a recirculating conduit () of exhaust gases. The intake manifold () includes a first inlet mouth () of the comburent air, a second inlet mouth () in communication with the recirculating conduit () of the exhaust gases, and a plurality of outlet mouths (), having a wall () positioned in front of each of the outlet mouths () and suitable for dividing the internal volume of the intake manifold () into two chambers (), the first chamber () being placed in communication with the first inlet mouth () and the second inlet mouth () and the second chamber () being placed in communication with the outlet mouths (), the wall () defining an opening () suitable for placing the first chamber () and the second chamber () in communication.

Intake manifold of comburent air for an internal combustion engine equipped with EGR

An auxiliary air conditioning system () for a motor vehicle (), comprising a first heat exchanger () adapted to be installed inside a passenger compartment () of the motor vehicle and an external unit () comprising an auxiliary engine (), an auxiliary compressor () driven by the auxiliary engine () and a second exchanger (). The system comprises a switching valve () for selectively setting a first refrigerating cycle operating mode in which the first heat exchanger () serves as an evaporator and the second heat exchanger () serves as a condenser, and a second heat pump operating mode, in which the first heat exchanger () serves as a condenser and the fluid of the second heat exchanger () is cut off and the operative fluid is allowed to flow through a heating device () to receive thermal power independently from the outside environment temperature.

Air conditioning system for a motor vehicle

An auxiliary power system for a vehicle, having an auxiliary internal combustion engine with a starter is described. An auxiliary alternator driven by the auxiliary engine and connected to a battery of the vehicle and a control unit, which is connected to the battery, and activates the starter of the auxiliary engine in the event the voltage of the battery is below a reference value, may be included.

Automotive auxiliary power system

A continuously variable transmission including an input shaft; a flywheel connected to the input shaft; a drive pulley connected to the input shaft and defined by a first and a second half-pulley defining a groove of variable width for a belt; and a centrifugal actuating assembly having a centrifugal actuating device, which activates above a first threshold value of the angular speed of the input shaft to connect the drive pulley to the flywheel by a clutch interposed between the first half-pulley and the flywheel, and a speed regulating device, which is active above a second threshold value of the angular speed of the input shaft to adjust the width of the groove of the drive pulley, and therefore the work diameter of the belt.

Automatic, mechanical, continuously variable transmission, particularly for a heavy-duty vehicle

A pulley for a continuously-variable-ratio drive, having a fixed half-pulley fitted to a shaft of the drive; a movable half-pulley mounted to slide axially with respect to the fixed half-pulley to define with it a V groove of variable size for a V belt; and a torque-sensitive, axial thrust compensating device having an acceleration cam and a deceleration cam, which are interposed between the fixed half-pulley and the movable half-pulley to generate thrust on the movable half-pulley in the compression direction of the belt in response to both a drive torque and a braking torque.

Pulley for a continuously-variable-ratio drive

A continuously-variable-ratio drive, having an input shaft; a flywheel integral with the input shaft; a drive pulley idle with respect to the input shaft and defined by two half-pulleys defining a groove of variable size for a V belt; and a centrifugal control assembly. The control assembly has a centrifugal actuating device which intervenes above a first threshold value of the angular speed of the input shaft to connect the drive pulley angularly to the flywheel by means of a friction clutch; and a speed adjusting device which is active over a second threshold value of the angular speed of the input shaft to adjust the size of the groove of the drive pulley and therefore the work diameter of the belt.

Automatic mechanically controlled continuously-variable-ratio drive

The drive assembly has: an input member and an intermediate shaft; an axial clutch device for connecting the input member and the intermediate shaft in rotary manner; and a pulley connected in rotary manner to the intermediate shaft and defined by two half-pulleys movable axially with respect to each other and engaging a drive belt, the distance between the half-pulleys determining the winding radius of the belt. A push member, movable axially, along the intermediate shaft, between two limit positions, exerts thrust on the two half-pulleys to determine, in direct relation with its own axial position, the axial distance between the two half-pulleys, and alternatively exerts thrust on the clutch device to release the clutch device when moved axially in the direction increasing the distance between the half-pulleys. A control device is also provided to vary, on command, the axial position of the push member.
