Particle filter regeneration process for internal combustion diesel engine of motor vehicle, involves regenerating particle filter by injecting fuel into exhaust line based on defined injection parameter i.e. temperature set point

摘要

The process involves measuring a parameter representative of a composition of soot accumulated in a particle filter (5), where the measuring process includes determination of a calorific value of fuel to be injected. A fuel injection parameter i.e. temperature set point of a temperature control loop of the particle filter, in an exhaust line (1) is defined in an upstream of the particle filter according to a measured parameter. The particle filter is regenerated by injecting the fuel into the exhaust line based on a defined injection parameter. Independent claims are also included for the following: (1) an injection Control device for regeneration of a particle filter of an internal combustion engine (2) a motor vehicle comprising a system for regeneration of a particle filter.
