Title: Intake quantity controller for engine
Inventor: SHINDO TAKAO
IPC: F02D9/02
Filed: 1989-06-09
Abstract: PURPOSE:To arbitrarily reduce the rate of change of the opening port area in a low opening degree region by constituting the title device so that an intake introducing pipe has a restricted inner wall surface for maintaining the small gap from the outside peripheral edge on one side of a throttle valve shaft in the case when the opening degree of the throttle valve is less than a prescribed value, continuously to a closed inner wall surface. CONSTITUTION:When a throttle valve 5 starts opening from an idle position X-X, an outside peripheral edge 5b shifts, increasing the gap little by little from a closed inner wall surface 6 along a restricted inner wall surface 10 or maintaining a nearly certain gap. Though, at the same time, the outside peripheral edge 5a gradually increases the interval from an opposed ventilating passage wall, the intake quantity increases, since the rate of increase of the opening area of the whole is little. After the passing through the restricted inner wall surface 10, the intake quantity increases at a rate in the equal degree to the conventional. Therefore, even in the considerably high opening degree region of the throttle valve 5, the engine operation is stabilized by setting the turning quantity of the throttle valve for the accelerator operation quantity to the equal degree to the conventional, and then the perfect opening is suppressed with the equal accelerator operation quantity, since opening is suppressed in a low opening degree region.
