摘要： The invention relates to a fuel injector having a solenoid valve for actuating an armature assembly which is configured in one piece or a plurality of pieces. A closing element is actuated via this in order to relieve the pressure in a control chamber. The armature assembly is guided in an armature guide which is fastened in the injector body by means of a valve-clamping screw. In a fixing region in the injector body, the armature guide has at least one circumferential recess which allows for deformation of the fixing region during fastening by the valve-clamping screw.

摘要： The metering servo valve comprises a valve body, an open/close element, and an electromagnet, and is housed in a shell of the injector. The electromagnet actuates a mobile armature for a travel defined by an arrest element, carried by the electromagnet, which is housed in a casing, fixed in the shell by means of a threaded ring nut. Said ring nut is screwed with a pre-set tightening torque on a thread of the shell. The casing has a resting surface designed to engage a shoulder of the shell. The surface is carried by an area of the casing designed to undergo deformation as a function of the tightening torque of the ring nut so as to enable fine adjustment of the travel of the armature.

摘要： The injector has a hollow body housing the body of the metering valve, which has a discharge hole for discharging the usual control chamber. The hole comes out at a flat surface of the valve body, and is engaged by a flat surface of a plate, under the control of an armature of an electromagnet. The armature is in the form of a disk, has substantially no stem, is connected to the hollow body by a leaf spring hinge, and has a surface having a spherical-bowl-shaped recess. A ball is located between the recess and another recess carried by a second surface of the plate. The valve body is fixed to the hollow body by a ring nut of a given height. And, to cover the distance between the valve body and the armature, a spacer member is preferably formed in one piece with the valve body.

摘要： The present invention relates to an injector for injecting fuel into the combustion chamber of an internal combustion engine. The injector (1) is actuated by an actuator (29) and includes a central chamber (5, 44), through which fuel under high pressure enters into a control chamber (3) that activates a nozzle needle (4). The central chamber (5, 44) is connected via a connector (7) to a high pressure source. In the injector body (13) between the central chamber (5, 44) and an end face (38) on the connector (7) are configured supply-line bores (30, 31), whose diameters (33, 34) are many times smaller than the diameters (36, 45) of the central chamber (5, 44).

摘要： A system and method for engine control determine a spilled fuel quantity for use in controlling pressure of a common rail fuel system. In one embodiment, a spilled fuel estimate is determined based on rail pressure and engine speed. Another embodiment determines a spilled fuel estimate based on a leakage quantity and a spill control quantity. The leakage quantity represents the amount of fuel leaked past the internal passages inside the injectors and is based on rail pressure alone. The spill control quantity is based on rail pressure and injector energizing time. The spill control quantity represents the fuel used to actuate the injector allowing the injected fuel into the cylinder during the combustion cycle. A more accurate determination of the quantity of fuel pumped based on spilled fuel and injected fuel may be used to improve the common rail pressure control, for example.
摘要翻译：用于发动机控制的系统和方法确定用于控制共轨燃料系统的压力的溢出燃料量。在一个实施例中，基于轨道压力和发动机速度确定溢出燃料估计。另一个实施例基于泄漏量和溢出控制量确定溢出的燃料估计。泄漏量表示喷射器内部通道内泄漏的燃料量，仅基于钢轨压力。泄漏控制量基于轨道压力和喷油器通电时间。泄漏控制量表示用于致动喷射器的燃料，允许喷射燃料在燃烧循环期间进入气缸。例如，可以更准确地确定基于溢出的燃料和喷射燃料泵送的燃料的量来改进共轨压力控制。
