Summary: | The invention relates to a method for estimating the overall dilution ratio of the oil of an internal combustion engine provided with a device for treating combustion gases requiring phases of treatment by post-injection of fuel into the cylinders of the engine, said method comprising steps of estimating the dilution ratio of fuel in oil (T1), characterised in that it also comprises at least one step of estimating the dilution ratio of the oil's own carbonaceous compound fractionation (T2) as a function of the ratio of fuel injected into the oil (T11), the overall dilution ratio (T) of the oil being the sum of at least said ratio of fuel dilution in oil (T1) and said dilution ratio of the oil fractionation. |
