Method for alignment of lambda sensor signal provided by lambda sensor arranged in exhaust duct of internal-combustion engine of motor vehicle, involves opening butterfly valve during fuel cut-off, and adjusting signal after opening valve |
摘要 |
<p>The method involves adjusting a lambda sensor signal (lam-Mes) during fuel cut-off of an internal-combustion engine (10). A butterfly valve (18) arranged within intake area (16) of the internal-combustion engine is opened during the fuel cut-off and during alignment of the lambda sensor signal, and the lambda sensor signal is adjusted after opening the butterfly valve during the fuel cut-off. The lambda sensor signal is assigned to a value that corresponds to oxygen concentration of 21 percentage. Independent claims are also included for the following: (1) a device for alignment of a lambda sensor signal (2) a controller program comprising a set of instructions to perform a method for alignment of the lambda sensor signal (3) a controller program product comprising the set of instructions to perform a method for alignment of the lambda sensor signal.</p> |
