Abstract (en)

[origin: WO2005083250A1] The invention relates to a method for determining the actual oxygen load (m02) of a 3-path catalyst (6) of a lambda-controlled internal combustion engine (1), whereby a value for the actual oxygen load (m02) is calculated from the signal of a pre-catalyst lambda probe (5) and the measured air mass flow rate by integration over time, whereby the post-catalyst lambda probe is initialised when the signal is interrupted.
