  • Patent number: 8024109
    Abstract: An abnormality determination apparatus for an intake amount control mechanism according to the invention includes a control portion which sets an allowable range of an opening amount of a throttle valve which provided in an intake passageway of an internal combustion engine based at least on an index value of an engine operation state, including an operation amount of accelerator, and on a lift working angle of an intake valve, and which determines that an abnormality is present in a state of driving of the throttle valve if an actual opening amount of the throttle valve is outside the allowable range set.
    Type: Grant
    Filed: March 23, 2009
    Date of Patent: September 20, 2011
    Assignee: Toyota Jidosha Kabushiki Kaisha
    Inventors: Naohide Fuwa, Kiyoo Hirose, Yuuji Miyanoo, Yuichiro Ido

  • Patent number: 7237530
    Abstract: A control apparatus for an internal combustion engine provided with a fuel vapor treatment system according to the invention includes a controller that discharges fuel vapor into an intake passageway by using the intake negative pressure, and which adjusts the amount of the intake air through the cooperative control of a variable control of at least one of the lift amount of an intake valve and the working angle of the intake valve, and a control of the degree of opening of a throttle valve. In addition, the control apparatus executes the variable control so that at least one of the lift amount and the working angle of the intake valve changes in accordance with the fuel vapor concentration in the fuel vapor treatment system.
