DIESEL PARTICULATE FILTRATION (DPF) SYSTEM
First Claim
6. A method for removing soot from exhaust gases of an internal combustion engine comprising:
- introducing a first portion of a filter material from a supply of the filter material into a path of exhaust gasses to collect the soot on the material; and
subsequently moving the first portion of the material out of the path while moving a second portion of the material from the supply into the path.

Abstract
A fiber-paper based Diesel particulate Filtration (DPF) apparatus possessing high filtration efficiency and a high porosity, the apparatus comprising at least two rollers capable of rotating over rotors with the help of a controlled motor and capable of supplying fiber paper at the exhaust gas inlet. As the exhaust gas moves over the fiber paper supplied from one of the rollers, the soot gets gradually collected on the fiber paper and keeps on increasing the backpressure thereon. The moment when the backpressure increases beyond a limit, the loaded section of the fiber paper is replaced by fresh fiber paper from the other roller. The loaded fiber is sent to an off-board regeneration facility for regeneration.

10. A Diesel Particulate Filtration (DPF) system comprising:
- a supply roller and a take-up roller;
a filter material disposed on the supply roller and having an end connected to the supply roller;
portions of the material between the supply roller and the take-up roller passing through exhaust gasses passing through the system; and
a motor for moving the portions of the material between the supply roller and the take-up roller. - View Dependent Claims (11, 12, 13)

14. A Diesel Particulate Filtration (DPF) system comprising:
- a supply of filter material, a first portion of the material being disposed in a path of exhaust gasses passing through the system to collect soot in the exhaust gasses; and
a motor for moving the first portion of the material out of the path while drawing a second portion of the material from the supply into the path. - View Dependent Claims (1, 2, 3, 4, 5, 15, 16, 17, 18, 19, 20, 21, 22, 23)
