Fiber Wound Electrically Regenerable Diesel Particulate Filter Cartridge for Small Diesel Engines

An electrically regenerable diesel particulate filter particularly suitable for small (less than 4.0 liters) diesel engines has been developed. The cartridge consists of a unique tubular heater which is wrapped with ceramic fibers. Two or more of these cartridges with integral heaters are used in building a diesel particulate filter system.

The features of this cartridge are described along with performance results. Performance and durability data are presented under both steady state and transient operating conditions.

System design using these cartridges in a forklift truck application is presented in this paper. Performance and durability data of the system is discussed.
