Title: Process for controlling the reduction of noxious emissions from gas engines
Inventor: KLEEBLATT HERBERT
IPC: F02D41/00
Filed: 1985-10-10
Granted: 1988-05-26
Abstract: In an automatic control method for reduction in the level of contaminants emitted by a gas engine, the automatic control process is orientated in accordance with the reference point at which lambda is equal to unity and enriches the mixture after detecting this point by a certain step. Subsequently the instantaneous probe potential is measured and used by an automatic control circuit as a set point, which so affects the actuator for setting the air ratio that the probe potential is kept constant at this set point. The automatic control system in keeping with the invention reacts immediately in response to a disturbance and does not have to wait until a renewed search for the reference point takes place.
