Method for operating an internal combustion engine having a plurality of cylinder banks

Lambda modulation for internal combustion engine, involves conducting exhaust gases by exhaust system, controlling air-fuel mixture ratio by fuel measuring system and adjusting lambda value by automatic control loop

Method for performing on board diagnosis of e.g. exhaust gas system of motor car, involves adjusting manipulated variables, and making decision whether to perform diagnosis process again in response to determined state variables

Lambda control for internal combustion engine regulates oxygen concentration in exhaust gas in front of catalytic converter on internal combustion engine

Method for the diagnosis of a catalytic converter which is arranged in an exhaust area of an internal combustion engine and device for carrying out said method

Method for checking operation of catalyst in exhaust system of internal combustion engine for motor vehicle, involves determining oxygen storage ability of catalyst using primary lambda probe after introducing reducing agent in catalyst

Method for detecting type of sensor or actuator connected to control unit or adapted for connection

Method for judging starting of catalyzer for cleaning exhaust gas of e.g. petrol engine, involves controlling air/fuel mixture in detection phase such that gas probe recognizes alteration of period during oscillation of control loop

Y-shaped automotive exhaust system tests functioning of first-stage inlet components during regeneration of downstream common catalytic converter

Lambda regulation method for use in internal combustion engine, involves forming adaptation contact whose changes swap regulation contact synchronously for changes in adaptation contact, and partly compensating changes in adaptation contact
