Abstract
The present disclosure relates to a computer system for determining a condition of an ammonia slip catalyst of a vehicle, the computer system comprising processing circuitry configured to: obtain upstream oxygen concentration information indicative of an oxygen concentration of exhaust gases upstream of said ammonia slip catalyst and downstream oxygen concentration information indicative of an oxygen concentration of exhaust gases downstream of said ammonia slip catalyst, and determine whether or not the ammonia slip catalyst is in an N2O production condition based on said upstream oxygen concentration information and said downstream oxygen concentration information. The disclosure also relates to a method and a vehicle.
Claims15
A computer system for determining a condition of an ammonia slip catalyst of a vehicle, the computer system comprising processing circuitry configured to:
- obtain upstream oxygen concentration information indicative of an oxygen concentration of exhaust gases upstream of said ammonia slip catalyst and downstream oxygen concentration information indicative of an oxygen concentration of exhaust gases downstream of said ammonia slip catalyst;
- and
- determine whether or not the ammonia slip catalyst is in an N2O production condition based on said upstream oxygen concentration information and said downstream oxygen concentration information.
A computer-implemented method for determining a condition of an ammonia slip catalyst of a vehicle, comprising:
- obtaining, by processing circuitry of a computer system, upstream oxygen concentration information indicative of an oxygen concentration of exhaust gases upstream of said ammonia slip catalyst and downstream oxygen concentration information indicative of an oxygen concentration of exhaust gases downstream of said ammonia slip catalyst;
- and
- determining, by the processing circuitry, whether or not the ammonia slip catalyst is in a N2O production condition based on said upstream oxygen concentration information and said downstream oxygen concentration information.
