摘要： A component of a fuel combustion system of an engine includes a body with a knurled conduction surface. The body is hollow and defines a central longitudinal axis. The body includes an outer surface, an inner surface, and an orifice surface. The outer surface defines an outer opening. The inner surface defines an interior chamber and an inner opening. The orifice surface defines an orifice passage extending between, and in communication with, the outer opening and the inner opening. The orifice passage is in communication with the interior chamber via the inner opening. The outer surface includes the knurled conduction surface. The knurled conduction surface has a boundary surface and a plurality of protrusions that project outwardly from the boundary surface. At least a portion of the knurled conduction surface is axially aligned with the interior chamber along the central longitudinal axis.

摘要： Systems and methods are provided for an engine. The system comprises a direct injection engine having a cylinder in which a piston is slidingly supported to form in combination with a cylinder head a combustion chamber; a fuel injector for the cylinder having a catalytic coated tip portion that projects into the combustion chamber; and an electronic controller to control the operation of the engine and operates the engine in a heating mode of operation if heating of the fuel injector tip is requested. Various methods for heating the fuel injector tip are proposed including operating the engine on a reduced number of cylinders and varying one or both of fuel injection timing and quantity of fuel injected and the ignition timing in order to increase the temperature of combustion.

摘要： An engaging projection of a valve body engages with an interlocking groove of a nozzle plate and the nozzle plate is rotated relative to the valve body. The engaging projection moves in a lateral groove of the interlocking groove while elastically deforming an arm part (elastically deformable portion), and the engaging projection is accommodated in a recess (lock position in the interlocking groove) of the arm part. A bottom surface of the recess of the arm part is pushed against the engaging projection of the valve body by the elastic force of the arm part, and the engaging projection of the valve body is seated and fixed on the bottom surface of the recess of the arm part. Accordingly, the nozzle plate is fixed to the valve body while being retained via the engaging projection and the interlocking groove (interlocking means).

摘要： A pressure relief valve for a common rail fuel system includes a hard ceramic spherical valve member that moves into and out of contact with a conical valve seat of a soft metallic valve body. Fretting damage to the valve is inhibited by using the dissimilar materials, and by using a guide pin that is allowed to move on the spherical surface of the ceramic spherical valve member. The valve member may be constructed of silicon nitride.

摘要： A high speed and high force magnetostrictive actuator is the preferred source of continuously controllable motion for the hydromechanical portion of a diesel fuel injector. The actuator converts continuously variable voltage and current into continuously variable force and displacement. A magnetostrictive actuator advances the state of the art of fuel injection by exerting continuously variable control through-out each injection event, including very fast transients free of overshoot or ringing. From rest, magnetostrictive fuel injector actuators have been tested to extend to their full distance of tens of micrometers without ringing and return to their rest position at near zero velocity. Complete cycles, from rest to rest, can occur in well under two hundred microseconds. A method of detecting fuel pressure takes advantage of the continuous variability in certain properties of the magnetostrictive alloy.
