Abstract: Crystallizer for the continuous casting of long metal products such as blooms or billets, of the type cooled by an external cooling jacket, in which, at least in the zone of maximum thermal peak, positioned around the zone of the meniscus or immediately below it, there are means present, made on the walls of the crystallizer, to condition the heat exchange between the walls of the crystallizer and the cast steel. The means to condition the heat exchange comprise concavities or depressions made on the internal wall of the crystallizer, made around the zone of maximum thermal peak, and having a distribution that, in terms of the overall area occupied by them per surface unit, is reduced until it is canceled toward the bottom at a certain distance from said zone of maximum thermal peak.

Abstract: A container tracking system comprising a mobile unit configured to be coupled to a container to be tracked and to communicate with a remote control unit through of a communication system. The mobile unit comprising a positioning module, an alarm module adapted to detect alarm conditions related to said container, and a communication module generating a tracking signal containing positioning data of the mobile unit and/or alarm information associated with one or more alarm conditions related to the container. Furthermore, the mobile unit is configured to evolve to a temporary deactivation state whenever a communication unavailability condition of the tracking signal through the communication system occurs.

Abstract: There is described a method of diagnosing a motor vehicle battery, wherein, at each start-up of the vehicle engine, a number of parameters, related to the pattern of an electric quantity supplied by the battery during a transient start-up state of the engine, are recorded; and the recorded parameters are then memorized to create a database which is used to determine the charge status of the battery.

Abstract: A method of diagnosing a cooling system of a vehicle engine, including the steps of: acquiring operating data relative to operation of the cooling system (cooling system radiator water temperature/fan rotation speed) during a trip time between turn-on of the engine and subsequent turn-off of the engine; processing the acquired data, and accumulating the data for each trip to create a database; and examining the location of the data within the database to determine malfunction and/or potential malfunction situations of the cooling system.

Abstract: A method of diagnosing a vehicle compressed-air generating system, the method including the steps of: acquiring a number of operating data items associated with operation of the compressed-air generating system between turn-on of the system and subsequent turn-off of the system; processing the acquired operating data items and accumulating the data items to create at least one database; and examining the location of the data items in the database to determine malfunction and/or potential malfunction situations of the compressed-air generating system.

Abstract: A control method for controlling injection of an engine having an oxygen concentration sensor generating a composition signal as a function of the oxygen difference in the exhaust gases with respect to the stoichiometric condition of the burnt air/fuel mixture, and a number of injectors for injecting fuel for an operating injection time in each operating state of the engine, and each of which is assigned, in each operating state of the engine, a respective calibration injection time determined at an initial engine calibration stage using a reference fuel.

Abstract: A method of controlling injection of an engine having an oxygen concentration sensor generating a composition signal correlated to the composition of the exhaust gases, and a number of injectors for injecting fuel for an operating injection time in each operating state of the engine, and each of which is assigned, in each operating state of the engine, a respective calibration injection time determined at an initial engine calibration stage using a reference fuel.

Abstract: An internal combustion engine is provided with a methane feed system including a plurality of methane injection devices respectively associated with the various cylinders of the engine. The methane injection devices are mounted within respective seats communicating with a distributing conduit or rail for feeding methane. The seats for the injection devices in the rail are formed in an auxiliary body separate from the intake manifold and the head of the engine. An electronic control unit provides for the control of the injection devices on the basis of signals indicative of the parameters of operation of the engine so as to carry out the methane injection at each cylinder when the rotational speed of the engine is lower than a predetermined threshold when the intake valve of the cylinder is open.
