Patent number: 10082108Abstract: A fuel injector for operation with combustible gas, having a gas nozzle assembly having at least one gas nozzle opening, and at least one gas nozzle needle associated with the gas nozzle assembly and accommodated in an axial holder so that the stroke of the gas nozzle needle can be controlled. Each gas nozzle opening leads out of the holder having a radial direction component at the nozzle end. The fuel injector has, in the holder, a needle seat upstream of the particular nozzle opening, which needle seat is provided for selectively blocking a combustible-gas flow path to the associated gas nozzle opening in interaction with the gas nozzle needle. The gas nozzle openings are distributed over part of the circumference in the circumferential direction of the gas nozzle needle. The holder, adjoining the needle seat and extending away therefrom axially in the upstream direction, is asymmetric with respect to an axial center axis through the gas nozzle needle.Type: GrantFiled: January 7, 2016Date of Patent: September 25, 2018Assignee: L'Orange GMBHInventors: Ingmar Joachim Berger, Markus Kalenborn

Patent number: 7377154Abstract: In a method for monitoring an exhaust gas limiting value of an internal combustion engine using an engine controller, the engine controller has at least one exhaust gas sensor, and an error signal is output when the exhaust gas limiting value is exceeded. If the emissions predicted for the present driving state are ascertained with the aid of an engine model and compared to the signal of the exhaust gas sensor or a comparison value for the emission derived therefrom, the prescribed driving cycle may be taken into account when certifying a limiting value monitoring system and a defective system may be reliably recognized in practical operation even in atypical driving states without resulting in erroneous triggering of error signals.Type: GrantFiled: July 20, 2006Date of Patent: May 27, 2008Assignee: Robert Bosch GmbHInventors: Joachim Berger, Rainer Strohmaier, Bernard Kamp
