  • Patent number: 7984701
    Abstract: The device is adapted to control the movement of a valve (1) of an internal combustion engine comprising a stem (1a) which may move in translation through an opening (2a) of a hollow guide body (2) and which ends in a mushroom head (1b) cooperating in operation with a valve seat (12) provided in a wall (13) of the engine head. The valve (1) may move in translation with respect to the hollow guide body (2) between a retracted position and a forward position in which the mushroom head (1b) respectively closes and opens the associated valve seat (12). The control device comprises an electromagnet (3) adapted, when energised, to retain the valve (1) in the retracted closed position, a first spring (7) associated with the valve (1) and tending to urge it towards the open position, and a second spring (8) also associated with the valve (1) and tending to oppose its transition into the open position.

  • Publication number: 20050175408
    Abstract: A safety barrier for road use comprises a barrier element (5) which can be displaced between an operative position, above the road surface, and an inoperative position, in which it does not substantially project above the road surface. Preferably provided is a number of sets of aligned barrier elements, rigidly connected to one another, the adjacent sets being connected together by articulated connecting structures (18) which enable one set of barrier elements (5) to be displaced between its inoperative position and its operative position without modifying the positions of the adjacent sets. In this way, one or more stretches of the barrier can be brought into the inoperative condition, leaving the adjacent stretches of barrier in the normal operative condition. The invention is particularly, although not exclusively, suited for the construction of traffic-divider barriers in road tunnels where it is necessary to eliminate the barrier rapidly in the event of an accident occurring.

  • Patent number: 6411886
    Abstract: A method of detecting and controlling detonation, including the steps of: generating (10) a vibration signal (D) proportional to the intensity of vibration on the crankcase; wide-band-filtering (11) the vibration signal (D) to generate a first intermediate signal; rectifying (12) the first intermediate signal to generate a second intermediate signal; integrating (13) the second intermediate signal to generate a first numeric value; calculating (14) a logarithm of the first numeric value to obtain a second numeric value (Xi); calculating (16) a difference between the second numeric value (Xi) and the mean value (&mgr;i) to obtain a third numeric value (&dgr;i) with a predetermined threshold value (&dgr;o); determining (18) the presence of detonation in the event the third numeric value (&dgr;i) has a first predetermined relationship with the predetermined threshold value (&dgr;o); forming (19, 21) a detonation index (Ii) indicating the behavior of the engine in terms of detonation; and obtaining (22) a spark l
