Abstract: A fuel heating apparatus and method are disclosed where a conductive coil is wrapped around an outer surface of at least a portion of a nozzle of a fuel injector. The coil and the nozzle are inductively cooperative with each other such that the coil, in response to a variable current through the coil, induces a heating of the nozzle. The inductively heated nozzle can heat fuel passing into an engine so as to cause the fuel to combust as it exits the heated nozzle. This arrangement allows for sparkles combustion of fuel in an internal combustion engine.

Abstract: An injector nozzle used with an internal combustion engine for guiding and shaping a fluid flow is provided. The injector nozzle has a fluid flow guide provided at an outlet of a nozzle body. The fluid flow guide has a plurality of fluid passageways for creating a plurality of stream jets. Each passageway has an orifice, through which a respective stream jet is discharged from a respective passageway. The imaginary extensions and the plurality of passageways converge to create at least one focal point, such that the plurality of stream jets impinge on each other to form a spray plume. The plurality of orifices of the fluid passageways are arranged on an imaginary circle on an exterior surface of the fluid flow guide. The plurality of orifices are radially asymmetrically distributed on the imaginary circle with respect to the central axis of the imaginary circle.

Abstract: The device for valve operation and setting the stroke of a valve (10), comprises an operating device (20), for displacing the valve body (12), which may be controlled by means of a pneumatic or hydraulic pressure medium. A flexible tube body (22) runs between the both end pieces (24, 26) of the operating device (20), the inner volume of which is pressurised with the pressure medium. One of the end pieces (24) is connected to the valve body (12) and a belt structure is fixed to both end-pieces (24, 26) which runs co-axial to the tubular body (22) and comprises two crossed belt groups, containing belts running in the same longitudinal orientation. A membrane (16) running perpendicularly across the valve housing (11) is connected to the valve body and elastically draws the valve body back on displacement. The valve stroke can be exactly controlled with just the size of the control pressure.

Abstract: The invention relates to an electromagnetic valve (2) for controlling an injection valve (1) of an internal combustion engine. Said electromagnetic valve comprises an electromagnet (34), a mobile armature (29), a control valve element (25, 26), which is moved with the armature (29), interacts with a valve seat (24), and which is provided for opening and closing a fuel drainage channel (17) of a control pressure space (14) of the injection valve. The electromagnetic valve also comprises a sliding piece (40), which guides the armature (29) and which, together with the armature (29) and the control valve element (25, 26), is arranged inside an armature space (51, 52). In order to reduce the armature rebound, the invention provides that the sliding piece (40) subdivides the armature space into a relieving space (52), which is connected to a fuel low-pressure connection (10), and into a hydraulic damping space (51), into which the fuel drainage channel (17) runs. Said damping space can be relieved from stress by at least one connecting channel (44, 47), which is provided with a restrictor (43, 48) and which leads up to the relieving space (52). As the electromagnetic valve (2) closes, a fuel pressure cushion acting upon the control valve element (25, 26) reduces the velocity of said control valve element (25, 26) before it comes into contact with the valve seat (24).
