Abstract:
1. A particle separator configured for the separation of particles from an exhaust gas stream of an internal combustion engine, the particle separator comprising: at least two heat transfer zones arranged in respective sections along respective lengths of a main flow direction of the exhaust gas stream, the main flow direction extending from an inflow side to an outflow side of the particle separator, the at least two heat transfer zones each having at least one of a different heat storage capacity, a thermal conductivity, and heat-transfer properties from the exhaust gas stream to the particle separator, each of the at least two heat transfer zones configured for a defined amount of heat to be transferred from the exhaust gas stream to the respective sections of the particle separator; and at least one insert element having a predetermined shape extending over a predetermined part of a distance of the main flow direction, the at least one insert element forming one of the at least two heat-transfer zones with a heat-transfer property different from that of an adjacent one of the at least two heat-transfer zones in the main flow direction, wherein the at least one insert has a shape in the form of at least one of a wall, a cooling rib, a sphere, a knob, a pin, and a spade.
