摘要： This system for directly injecting fuel into a cylinder combustion chamber of an internal combustion engine comprises at least a fuel injector (3) and means (4) for priming the fuel in the chamber (1). The system is characterised in that the said at least one injector (3) is arranged parallel to a direction tangential (T) to the chamber (1), offset with respect to of the chamber longitudinal axis (X-X) and inclined relative to a plane transversal (P) to the said axis (X-X), towards the priming means (4), to create in the chamber, an air/fuel vortex towards the priming means.

摘要： A solenoid valve (1) having a fuel inlet (3) and a fuel outlet (4) and containing a solenoid coil (5) combined with power supply control means therefor, as well as a magnetic piece (6) and a plunger (7) with facing contact surfaces. The plunger (7) is connected to sealing means (8) for opening and closing said outlet (4) by moving the plunger (7) relative to the magnetic piece and causing mutual engagement between the contact surfaces thereof. Said solenoid coil power supply control means (5a) are arranged to apply a current (I) to said coil that has a surge phase (A) and a plateau phase (M). At the end of the surge phase, the current has a shallower slope (A2) than at the start (A1) thereof, whereby the impact of the plunger (7) against the magnetic piece (6) is reduced as the valve body outlet is opened.

摘要： A system comprising a fuel tank (20), pressurised fuel accumulation means (21), means (26) for connecting the accumulation means to means (27) for injecting fuel into the engine, and a control valve (29) positioned between the connecting means (26) and the tank (20) and connected to control means (30) for opening and closing the valve to generate a fuel pressure wave by means of a surge effect in the connecting means up to the injection means, and thereby inject fuel into the engine. Said system further comprises means (30) for controlling the fuel pressure in the accumulation means (21) to enable adjustment of the fuel pressure wave amplitude in the injection means (27) and thus also of the amount of fuel injected into the engine, in accordance with the operating conditions thereof.
