Abstract

The filter (10) has a filtering panel (80) that is placed inside a filter body (100) for filtering soots. A compression and evacuation unit comprises an endless screw (15) that is rotated in a tunnel (40) in which the soots are collected, so as to compress the soots and to displace the compressed soots along threading of the endless screw for storing the compressed soots in a serpentine-shaped soot storage pipe. The screw cooperates with a mobile valve of a compaction unit that enables compaction of the soots.

As. we can see in the figure of figure 5d., when it is deformed, it passes through the tooth. saw 33 against which it was stuck and ... moves to the next tooth 3 ', This process sereprodOit. tooth by tooth until filling: pipe. 30. Alternatively, the same compaction can be obtained with a storage pipe 25 internal sawtooth saws of flexible and deformable nature, anda rigid valve 3. Figure 1 shows another variant of the continuous movement of the chopper.The storage pipe is a serpentine pipe with a smooth inner wall and a valve which resists the pipe. The pressure of the soot is equipped with an urethane 34, preferably an O-ring, the resistance of the valve 32. It resists the growth of soot It is at its friction The speed of movement of the valve 3a, and soothes 1, is proportional to the force exerted by soot It is inversely proportional to the strength of the joint 34. The accumulation of soot can be optimized by the dimensional dimension of the resistance to the displacement of the joint, which can be corrected. In the described embodiments, the filter for the art has been placed in the form of cylinders, in particular the pipe and the filter can be positioned in several ways in Figure 41. Storage is the filter, in Figure 5b, 115 are side by side. get out of the box i nvention, the serpentine pipe can be t_s contained in a box orE drawer, or can be 0-antenna freely hooked to the tunnel spout of the filter. Seleri case the emptying can be carried out replacement of the drawer or the haler containing the coil, or by directly removing the serpentine himself, or by sucking the soot, the drawer or the topper: container. the coil or the spiral, small to be hooked, OR suspended from the filter body, The doming device according to the invention is applicable to any type of motor vehicle equipped with a heat engine. It allows space between emptying intervals and reduces CO2 emissions by reducing fuel consumption as it will no longer be necessary to inject the fuel to make them. regeneration of the filter. particles ..
