Abstract

The process establishes an estimate of the dilution rate (Pdil) of fuel in oil and authorizes the regeneration when the estimate of the dilution rate is less than a preset dilution threshold. The process handles data and controls the engine to achieve regeneration of the particle filter when necessary. The variation in dilution rate (dPdil) is evaluated by a first function (-Fevap) representing the evaporation of the fuel while no regeneration of the filter is in progress, and by a second function while the filter is being regenerated. The second function is the sum of the first function and a third function (Grege). The variation in the dilution rate is evaluated as a function of the speed of rotation of the engine (N) and a variable representing the load on the engine (Qc), such as the flow of injected fuel. The functions are recorded in the form of graphs.
