Publication number: 20030029396Abstract: Oil injection apparatus and methods for injecting oil directly between the cylinder sleeves and the pistons of both cylinder banks in a v-type engine are described. In one embodiment, and with respect to each cylinder, an oil port in the engine block extends to an annular groove in the cylinder wall. An oil pump supplies lubricating oil to the port via a conduit, and under the control of a control unit. In operation, if the piston is thrust into the cylinder wall at the location of the groove when oil is being injected, the oil flows into the groove and is dispersed as the piston moves past the groove on the next stroke. If the piston is not thrust into the cylinder wall at the time oil is introduced, the oil flows into the cylinder and is dispersed by the piston.Type: ApplicationFiled: October 10, 2002Publication date: February 13, 2003Inventors: David Haman, Richard P.

Publication number: 20030029414Abstract: A method for controlling an injector is described, where the trigger signal (Ua) for the actuator is controlled as a function of the amplitude and the duration. The actuator, using an hydraulic coupler, actuates a control valve which, at a low voltage, operates in a ballistic mode and opens up an opening cross-section to an inlet channel (ZK). The opening cross-section (8) becomes smaller with increasing trigger voltage (Ua), and the fuel quantity to be injected increases. The control valve (5) is brought from ballistic mode to nonballistic mode via the amplitude and duration of the trigger voltage (Ua). The delivery duration (FD) and the amplitude of the trigger voltage (Ua) are tuned to each other so that one or several jumps may occur, during which a switch is made from one voltage value (Ua) to another voltage value (Ua), and from one delivery duration to another delivery duration (FD). The method is preferably used in a unit injector system such as is used in direct injection.Type: ApplicationFiled: July 24, 2002Publication date: February 13, 2003Inventors: Juergen Boss, Klaus Zimmermann, Andreas Hoyler

Publication number: 20030029421Abstract: The present invention finds application in engines using mechanically actuated electronically controlled fuel injectors having direct control needle valves. In valves such as these, a spill control valve member controls fuel pressurization within the injector while a needle control valve member controls the timing and duration of the injection event. However, when the momentum of fuel exiting the fuel injector past the spill valve is greater than that of the tappet and plunger moving toward their downward positions, engine components upstream of the tappet can briefly separate and re-engage, which can result in increased mechanical noise levels. Therefore, the present invention is directed to maintaining sufficient contact force in the various engine components to reduce the mechanical noise levels by positioning a flow restriction between the fuel pressurization chamber of the fuel injector and a fuel source.Type: ApplicationFiled: August 10, 2001Publication date: February 13, 2003Inventors: Dana R.

Publication number: 20030029440Abstract: According to prior art, such windows are typically configured as a multiple glass pane module which is provided with at least two transparent glass panes (1, 2) that are held by means of distance pieces (3) in such a way that said panes are spaced apart. Said distance pieces are glued together with said panes (1, 2) in a gas-tight manner. The aim of the invention is to provide a gas pressure compensation between the inner chamber between the two panes (1, 2) and the surroundings without said panes getting dirty. According to the invention, the window is designed in such a way that at least one opening (5) is embodied in the distance pieces (3). Said opening is closed by means of a permeable filter (6) that enables gas to penetrate for pressure compensation but prevents steam and vapours to enter.Type: ApplicationFiled: September 3, 2002Publication date: February 13, 2003Inventors: Oliver Gros, Kurt Leuntner
