    Abstract: A method of initiating regeneration of a particulate filter for a diesel engine having a common rail injection system permitting, at each engine cycle and in each cylinder of the engine, a fuel injection strategy performing one or more of the following injections: a main injection; a first pre-injection preceding the main injection and performed at the compression stroke; a second pre-injection preceding the main injection and following the first pre-injection; a first post-injection following the main injection; and a second post-injection following the first post-injection and performed at the exhaust stroke; the second pre-injection and the first post-injection being performed close enough to the main injection to participate, together with the main injection, in the actual fuel combustion phase. The method of initiating regeneration of the particulate filter provides for implementing, at each engine cycle and in each cylinder of the engine, a fuel injection strategy wherein one or more of the first and second pre-injection, the main injection, and the first and second post-injection are performed, and wherein the timing of one or more of the injections performed is varied with respect to the timing of the injections

    Abstract: In a gas-supply system for supplying a generic engine of a vehicle type, comprising electronic control means for controlling delivery devices associated to various engines, said electronic control means are programmed for processing the data regarding the low-pressure part of the system according to a predetermined algorithm, at predefined instants, in order to enable timely detection of incorrect functioning of a solenoid valve set in a position corresponding to a pressure-reducing device set between the gas tank and a manifold for distribution of the gas to the delivery devices. The system is moreover able to detect possible gas leaks from the low-pressure part of the system. The electronic control means are moreover able to process the data regarding the high-pressure part of the system, according to a predetermined algorithm, during operation of the system in order to enable timely detection of incorrect functioning of the valve set immediately at the outlet of the tank or to detect a possible gas leak from the high-pressure part of the system.

    Abstract: The injector has a hollow body housing a fuel metering valve closed by a closing spring; and a support housing an electromagnet controlling an armature. The support is connected to the hollow body, and the armature provides for opening the valve. The armature is fitted inside the hollow body by means of a leaf spring hinge having an annular portion fixed between the hollow body and the support, and a projecting radial tongue fixed to a central portion of the armature. The tongue, together with at least one radial appendix of the leaf spring hinge, provides for arresting the armature with a predetermined clearance with respect to the core of the electromagnet.
