  • Publication number: 20240134596
    Abstract: The content output device includes an information acquisition unit, a content generation unit and an output unit. The information acquisition unit acquires driving state information which is information related to a current driving state of a vehicle. The content generation unit acquires one or more content elements corresponding to a trigger condition, from among a plurality of content elements combinable with each other, when the driving state information satisfies the trigger condition, and generates an output content using the acquired content elements. The output unit outputs the output content.

  • Publication number: 20140116543
    Abstract: A fuel supply system includes a fuel tank, a filler pipe through which fuel is supplied to the fuel tank, and a storage tank in which a fuel additive that is to be supplied to the fuel tank is stored. An extended portion is formed at a portion adjacent to a communication port of the filler pipe and to which fuel directly flows when the fuel is supplied to the fuel tank. The fuel tank includes an injector that injects the fuel additive from the storage tank into the fuel tank. The fuel additive is injected into the extended portion.

  • Patent number: 8449643
    Abstract: An exhaust gas cleaner which can attain an improvement in the efficiency of particulate filter regeneration and has excellent durability. The exhaust gas cleaner, which purifies an exhaust gas discharged from an internal combustion engine, comprises: a gas channel through which the exhaust gas flows; and a DPF (17) disposed in the gas channel and having many pores. The DPF (17) has an introduction surface (171) which comes into contact with the exhaust gas, the surface (171) having been almost wholly coated with a microporous material (18) having micropores with a smaller pore diameter than the pores. This microporous material (18) comprises a support made of an oxygen-storing/releasing oxide having one or more elements selected from the group consisting of alkaline earth metal elements, transition metal elements, Group-12 elements, and Group-13 elements and a silver-containing catalyst deposited on the support.
