20090032620 | METERING SERVOVALVE AND FUEL INJECTOR FOR AN INTERNAL COMBUSTION ENGINE - A metering servovalve for a fuel injector of an internal combustion engine has an electro-actuator and a fixed valve body, which defines a control chamber communicating with an inlet and with an outlet channel. The outlet channel has at least one calibrated restriction and exits through the lateral surface of an axial stem, on which a sleeve slides, in a substantially fluid-tight manner, to open/close the outlet channel and so vary the pressure in the control chamber. The outlet channel is closed by an end portion of the sleeve that is elastically deformable in a radially outward direction, under the thrust of the fuel pressure, to increase the diameter at which the seal against the valve body is formed, with respect to a non-deformed state, and to generate a radial unbalancing force on the sleeve upon opening when the outlet channel is closed. | 02-05-2009 |
20100162992 | FUEL INJECTION SYSTEM WITH HIGH REPEATABILITY AND STABILITY OF OPERATION FOR AN INTERNAL-COMBUSTION ENGINE - The system comprises an injector controlled by commands of a control unit. The injector comprises a dosing servo valve having a control chamber provided with an outlet passage that is opened/closed by an open/close element that is axially movable. The open/close element is carried by an axial guide element that is separate from an anchor of an electromagnet. The open/close element is held in the closing position by a spring acting through an intermediate body. Preferably, the strokes of the open/close element and of the anchor are chosen so as to eliminate, upon closing of the solenoid valve, the rebounds of the open/close element subsequent to the first rebound. The control unit controls an injection comprising a pre-injection and a main injection, via two distinct electrical commands, which are spaced apart by a dwell time such as to occur in an area of reduced variation of the amount of injected fuel; therefore, the stability of operation of the system increases as said dwell time varies. | 07-01-2010 |
20120035832 | HIGH OPERATION REPEATABILITY AND STABILITY FUEL INJECTION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - A fuel injection system for an internal combustion engine, comprising: at least one fuel electroinjector; and one electronic control unit designed to supply the fuel electroinjector, in a fuel injection phase in an engine cylinder, with at least a first electrical command to perform a pilot fuel injection, and a second electrical command to perform a main fuel injection. The first and second electrical commands are separated in time by an electrical dwell time such that the main fuel injection starts without interruption with respect to the pilot fuel injection. The electrical dwell time between the first and second electrical commands belongs to an electrical dwell time range in which the total fuel amount injected in the pilot and main fuel injections in a fuel injection phase in an engine cylinder is substantially constant. | 02-09-2012 |
