open-loop catalytic converter
- open-loop catalytic converter
A preset converter which does not use an oxygen-sensor control system and thus operates without feedback. The opposite is computer-controlled catalytic converter. Certain engine management systems deactivate emission control systems (such as EGR and/or oxygen sensor control) under certain operating conditions (e.g., full-throttle driving); i.e., the electronic control module operates in the open-loop mode
