Patent number: 4644922Abstract: The invention is directed to a method and an apparatus for controlling the overrun mode of operation of an internal combustion engine, wherein instantaneous values of the relevant negative speed change of the internal combustion engine are sensed and evaluated to control the overrun mode. In this arrangement, a higher resume speed which is selected on commencement of the overrun mode and reduced to a lower speed limit after a predetermined time function, can be shifted additionally in dependence on the negative speed change. Further, to keep an internal combustion engine from stalling, the actual value of the negative speed change can be compared with a predetermined desired value; if it exceeds that value, the decision for a resume of fuel delivery can be made without delay.Type: GrantFiled: October 22, 1985Date of Patent: February 24, 1987Assignee: Robert Bosch GmbHInventors: Otto Glockler, Dieter Gunther, Ulrich Steinbrenner

Patent number: 4603670Abstract: A method of and a device for regulating air-fuel ratio of an internal combustion engine includes an oxygen or lambda probe and a signal processing unit connected to the lambda probe. The change-overs of the lambda signal at the output of the lambda probe are compared with a succession of adjustable first time intervals t.sub.1 and, when no change-over is detected during the first time interval, the output signal from the signal processing unit which controls the air-fuel ratio is abruptly changed in a jump. To avoid overshoot of the output control signal, there is provided a resetting unit by means of which the jump of the control signal is reversed when the change-over of the lambda signal occurs in an additional monitoring time interval t.sub.2 following the first monitoring time interval t.sub.1.Type: GrantFiled: July 5, 1984Date of Patent: August 5, 1986Assignee: Robert Bosch GmbHInventors: Richard Bertsch, Dieter Gunther, Hans Schnurle, Ulrich Steinbrenner

Patent number: 4492204Abstract: A fuel metering system and method for an internal combustion engine is proposed, having a lambda regulation device and a warm-up enrichment, in which at the onset of regulation the warm-up enrichment is reduced or turned off for the purpose of not having an abnormally high control stroke when transferring to a closed-loop operation and thereby rapidly attaining a stable lambda value.Type: GrantFiled: August 25, 1982Date of Patent: January 8, 1985Assignee: Robert Bosch GmbHInventors: Richard Bertsch, Dieter Gunther, Ulrich Steinbrenner

Patent number: 4449508Abstract: An electronically controlled or regulated fuel metering system for an internal combustion engine having one sensor each for the air flow in the intake tube and for the throttle valve position is proposed. In accordance with the signals of these sensors, influence can be exerted upon at least one of the operating states of lambda regulation, full load and fuel quantity limitation. The fundamental concept is that not only the air flow rate signal or only the signal relating to an opened throttle valve should be evaluated as a full-load signal but that the full-load state is presumed to exist when, with the throttle valve opened, the air throughput in the intake tube simultaneously exceeds a predetermined value as well. The same condition applies to full-load enrichment. The overall result is cleaner exhaust gas.Type: GrantFiled: September 13, 1982Date of Patent: May 22, 1984Assignee: Robert Bosch GmbHInventors: Otto Glockler, Dieter Gunther, Michael Horbelt, Ulrich Steinbrenner
