Title: Fuel injector for internal combustion engine
Inventor: AGUSTIN ULRICH DR ING
IPC: F02M63/00
Filed: 1996-11-15
Granted: 1998-01-22
Abstract: The injector has a spring loaded needle (4) operated by a control piston (5) to open and close the fuel feed. A control valve comprising a spring loaded piston (27) is fitted between the fuel inlet (8) and the feed to the needle. This piston has a sealing profile at the bottom end to locate in a valve seat (16) in the bottom of the injector. The piston only reaches the sealing position if there is a fault in the injector control. This effectively limits the maximum amount of fuel that can be injected in one pulse. The control piston has a flow limiter for the fuel flow between injection pulses. The upwards travel of the control piston is limited by a stop (20) on the shaft of the needle, or by a stop (20') on the inside wall of the injector bore.

Title: Monitoring alignment of beam characteristic of object sensor
Inventor: LUCAS BERNHARD
IPC: G01S13/931
Filed: 1997-02-26
Granted: 1998-10-29
Abstract: The method monitors the alignment of an object sensor (10) especially the vertical alignment of a radar sensor, not angle resolving in this plane. The object sensor using measurement waves transmitted, reflected and received again, determining at least one distance (d(t)) of a measurement object in the detection range. A reference reflector (11) serves as the measurement object, which during at least one measuring cycle, moves on a determined track (12a, b) so that different distances (d(t)) and different angle positions (gamma(t)) between the object sensor and the reference reflector are produced. An intensity distribution (P(gamma)) of the measurement wave reflected by the reference reflector is determined (206). Based on the determined intensity distribution, the alignment of the beam characteristic of the object sensor is monitored (207, 208) and a characteristic is produced, based on which a false alignment of the beam characteristic of the object sensor can be identified (210).
