Abstract: The present disclosure relates to a diesel exhaust treatment device including a catalytic converter positioned upstream from a diesel particulate filter. An electric heater is positioned between the catalytic converter and the diesel particulate filter. A shore station can be used to provide power and combustion air to the diesel exhaust treatment device during regeneration of the diesel particulate filter.

Abstract: The present disclosure relates to a pulse cleaner for cleaning a diesel exhaust treatment device. The pulse cleaner includes a cabinet, a diesel exhaust treatment device mount positioned within the cabinet for mounting the diesel exhaust treatment device during pulse cleaning, and a collection filter positioned within the cabinet for collecting material displaced from the diesel exhaust treatment device during cleaning. The pulse cleaner also includes a pulse generator for generating pulses that are each directed at a majority of a face of the diesel exhaust treatment device when the diesel exhaust treatment device is mounted at the diesel exhaust treatment device mount. The pulse generator includes a pressure tank for accumulating pressurized air, and a valve arrangement that flushes the pressurized air from the tank. A pulse of air for cleaning the diesel exhaust treatment device is generated each time the tank is flushed.
