  • Patent number: 11067019
    Abstract: A filter is disposed on an exhaust path of the internal combustion engine to capture particulate matter exhausted from the internal combustion engine. A controller is caused to execute regeneration control that incinerates the particulate matter captured on the filter. The controller accomplishes the regeneration control by executing lean incineration control and stoichiometric incineration control in combination with each other. The lean incineration control incinerates the particulate matter, keeping an air-fuel ratio of the internal combustion engine to be leaner than a logical air-fuel ratio. The stoichiometric incineration control incinerates the particulate matter, oscillating the air-fuel ratio of the internal combustion engine about the logical air-fuel ratio as an average air-fuel ratio at a predetermined first cycle.

  • Patent number: 11060512
    Abstract: An elongate fiber artificial muscle includes or consists of an elongate carbon or glass fiber and at least a partial coating of a polymer, and preferably a full shell coating to form a core-shell arrangement, that is volumetrically responsive to thermal changes or to moisture changes. Additional elongate fiber artificial muscles of the invention include a plurality of elongate carbon or glass fibers that are infiltrated between the fibers with a polymer that is volumetrically responsive to thermal changes or to moisture changes. In a fabrication method, the rheology (flow characteristic) of a polymer precursor is adjusted with solvent so it is less viscous. A fiber or plurality of fibers (pre-twisted or untwisted), such as a tow is dipped in the polymer precursor. The fiber or fibers is then pulled out of the polymer precursor and hung to allow polymer to distribute and then cured and can be twisted to coil prior to curing.
