  • Publication number: 20230250783
    Abstract: A hybrid electric vehicle includes an engine having an in-cylinder injection valve, a fuel supply device that supplies fuel to the in-cylinder injection valve, a motor that can generate an electric power through the use of a motive power output from the engine and can output a running motive power, and an electrical storage device that exchanges electric power with the motor. A deposit removal process where deposits adherent to the in-cylinder injection valve are removed by setting a pressure of fuel supplied to the in-cylinder injection valve to a predetermined pressure higher than a normal pressure and injecting fuel from the in-cylinder injection valve is performed during the performance of a forcible charging process for the electrical storage device, and the forcible charging process is continued until the pressure of fuel is returned to the normal pressure after the end of the deposit removal process.
