Title: Method and device for lambda control
Inventor: SCHNAIBEL EBERHARD DIPL ING
IPC: F02D45/00
Filed: 1988-11-09
Abstract: A device for lambda control operates on an internal combustion engine (11) with a catalytic converter (12) and one lambda probe (13.v) attached upstream and one lambda probe (13.h) attached downstream of the said catalytic converter (12). The device integrates with an integration means (15) the difference between the actual lambda value measured by the downstream probe and the set lambda value to which the system is to be adjusted. The integration value is used as set control value for a means (16) for lambda control. This device and the associated method permit adjustment to be carried out to the actually desired set lambda value even if the upstream lambda probe makes incorrect measurements, e.g. because of hydrocarbons in the exhaust gas upstream of the catalytic converter or, in the case of continuous control, because of faulty linearisation of the characteristic curve of the probe. <IMAGE>
