Björn Häggendal has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9850795
    Abstract: A process is provided for regenerating an exhaust gas after-treatment device in an exhaust line of an internal combustion engine arrangement, the exhaust line including a particle filter. The process includes identifying when soot loading of the particle filter exceeds a predetermined level. After that, temperature of exhaust gases at the particle filter is maintained within a first temperature range until at least one of a predetermined period of time has lapsed or a determination is made that soot loading of the particle filter is below the predetermined level. After that, the temperature of the exhaust gases at the particle filter is increased to within a second temperature range above the first temperature range. An internal combustion engine arrangement is also disclosed.
    Type: Grant

  • Patent number: 9114985
    Abstract: A fuel processor for generating hydrogen rich gas or cleaned hydrogen rich gas from hydrocarbon fuel includes an inner housing and an outer housing defining a mantel space between them, wherein at least one fuel reformer unit for reforming hydrocarbon fuel to a hydrogel rich gas and optionally a gas-cleaning unit for cleaning the hydrogen rich gas from unwanted by-products are arranged in the inner housing. The fuel processor further includes a processor inlet for introducing hydrocarbon fuel into the inner housing and a processor outlet for releasing cleaned hydrogen rich gas from the inner housing. The outer housing further includes a fluid inlet for introducing a heat transporting fluid into the mantel space. The inner housing includes at least one opening for providing a fluid-connection between the inner housing and the mantel space. A method for operating such a fuel processor is also provided.
