Yuuji WAKAI 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).

  • Engine system, engine system control device, engine system control method, and program
    Patent number: 10753269
    Abstract: A control device according to the present invention determines whether a demand load demanded of an engine exceeds a load threshold. The control device starts an electric motor if the demand load exceeds the load threshold. If the demand load is equal to or less than the load threshold, the control device performs control such that the degree of opening of an on-off valve increases monotonically with respect to the demand load. The control device switches the on-off valve from an open state to a closed state when the electric motor starts.
    Type: Grant
