  • Method of conditioning a particle filter
    Patent number: 9599051
    Abstract: A method of conditioning a particle filter provided for receiving exhaust gases from internal combustion engine is provided and includes providing a first engine control mode and a second engine control mode, wherein in the second engine control mode at least one combustion control parameter that affects the characteristics of particles emitted together with and carried by the exhaust gases from the engine is different in relation to the first control mode such that the filling rate of the particle filter with particles is increased compared to the filling rate that would have been achieved with the first engine control mode, determining a soot loading status of the particle filter, and temporarily applying the second engine control mode to the engine based on the soot loading status.
