Patent DE-19834867-A1 (DE)
Title: Injector for common-rail direct-injection diesel engines
Inventor: BUERGLER LUDWIG DIPL ING
IPC: F02M47/02
Filed: 1998-08-01
Abstract: The injector has two spring-loaded concentric fuel pins, each of which opens and closes a group of nozzles. The operation of the pins is partly or fully independent. The inner pin opens only at relatively high engine speeds and power outputs. The fuel pressure at which the outer, hollow pin opens is controlled by the piston (11) of a control unit (17) arranged on the injector axis (2). The piston resists the opening of the pin due to the pressure of fluid in the cylinder (18). Fluid is fed through a restrictor (Z) from either from the common rail, or from a separate source. A bleed orifice (A) and an electromagnetic or piezoelectric valve (20) control the pressure on the piston. The valve acts in response to engine operating parameters.

Title: Automatic control of particle grading in, recirculation to, seeding and height of fluidized bed
Inventor: HERBST BRENDAN
IPC: B01J8/00
Filed: 1999-04-15
Abstract: A fluidized bed, increases the size of particles fed to it. A coarse fraction of the growing particles is extracted automatically. The fraction is determined from the total mass of fluidized particles and height of the fluidized bed, these values being measured. Preferred Features: Separation of coarse particles to be removed, and fine fraction to be recycled, is achieved by upward flow classification. Other suitable methods may be used. Sensors measure bed height and may be external to the reactor. A differential pressure measurement, establishes total mass of particles. The method is carried out in stages or continuously. An algorithm, illustrated graphically as a logic flow diagram, connects the stages used. Other unspecified physical principles may be employed to determine the solids recycle ratio. Fluidized bed height may be deduced from other diverse measurements.
