  • Patent number: 11951846
    Abstract: In a structure of a disconnect plug of an electric vehicle, a plug bracket is raised from an inside of a battery unit to an inside of a bulge formed on a floor panel under rear seats for preventing a submarine motion of a passenger. In addition, a disconnect plug is detachably attached to a front face of a plug bracket, and an opening for accessing to the disconnect plug is formed on a front wall of the bulge. Further, a cover for covering the opening capable of being opened and closed is provided on a trim beneath a front face of a seat cushion of the rear seats.

  • Patent number: 11767798
    Abstract: An engine including a main fuel injection valve, a pilot fuel injection valve, a liquid fuel supply rail pipe, and a pilot fuel supply rail pipe. The main fuel injection valve supplies liquid fuel from the liquid fuel supply rail pipe to a combustion chamber during combustion in a diffusion combustion system. The pilot fuel injection valve supplies pilot fuel from the pilot fuel supply rail pipe to the combustion chamber in order to ignite gaseous fuel during combustion in a premixed combustion system. The liquid fuel supply rail pipe is disposed at one side of an imaginary vertical plane including an axis of a crank shaft. The pilot fuel supply rail pipe is disposed at the side of the imaginary vertical plane at which the liquid fuel supply rail pipe is disposed.
