Abstract: An internal combustion engine assembly comprising a fuel reformer, a combustion chamber and a controller. The fuel reformer comprises a first channel and a second channel, a portion of the second channel being adjacent to a portion of the first channel to facilitate heat exchange between the first and second channels. The first channel comprises a catalyst selected to reform ammonia to hydrogen and nitrogen. The first channel is configured to receive ammonia, pass the ammonia over the catalyst and output a first mixture comprising ammonia, hydrogen and nitrogen. The composition of the first mixture depends on a first reformer temperature of the first channel. The combustion chamber is configured to receive the first mixture from the fuel reformer; to receive an oxidant; to combust the first mixture in the oxidant to produce heat and a first product; and to output the first product. The second channel of the fuel reformer is configured to receive the first product.

Abstract: The present disclosure refers to a method for regenerating a filter adapted to remove particulate material from a gas. The disclosed method comprises at least producing at least one electric arc discharge pulse, the at least one electric arc discharge pulse being adapted to generate at least one pressure wave so that the particulate material is being dislodged from the filter. In addition, the disclosure refers to a filter regenerating arrangement and a diesel particulate filter.
