Patents by Inventor Yasunori IWAYA

Yasunori IWAYA 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).

  • Intake system
    Patent number: 11952068
    Abstract: Intake efficiency in an intake system is improved. An intake system takes air through an air inlet duct extending from an air cleaner case, and includes a vortex generator that causes the flow of the intake air inside the air inlet duct to rotate around an axis of the air inlet duct.
    Type: Grant
    Filed: March 24, 2022
    Date of Patent: April 9, 2024
    Assignee: HONDA MOTOR CO., LTD.

  • Fuel injection controller for internal combustion engine, and engine including the same
    Patent number: 9822726
    Abstract: In a fuel injection controller, a first throttle opening TH0 is defined at a specific time P2. The P2 is a specific time later than the peak value of an intake pipe internal pressure PB of a previous cycle. In the cycle, P3 is a specific time that is set immediately before the calculation of the injection time. A second throttle opening TH2 is defined at P3. The fuel injection controller corrects a fuel injection amount based on variation in correction time ta0 at the first throttle opening TH0 to correction time ta1 at the second throttle opening TH1. The time P2 is later than time P1, which is the peak value of the intake pipe internal pressure of the previous cycle. Accordingly, the fuel injection amount correction is completely unaffected or only slightly affected by the intake pipe internal pressure, thus ensuring close-to-ideal correction.
