Abstract: An apparatus for enhancing the control response of EGR recirculation rate. For EGR control, this apparatus contains a throttle valve for controlling the opening of an engine air intake passage (i.e. throttle valve for EGR control), and an EGR valve for controlling the flow rate of the exhaust gas recirculated into the air intake passage. The apparatus also includes a first air intake body containing the throttle valve, drive motor thereof and reduction gear mechanism, and a second air intake body containing the EGR valve, drive motor thereof and reduction gear mechanism. The first and second air intake bodies are connected with each other to form an integral assembly and are equipped with the first and second covers for protecting the respective reduction gear mechanisms. At least a circuit board for controlling the drive of the reference value is incorporated in at least one of said covers. The circuit board can be equipped with a circuit for controlling the drive of the EGR valve, in addition to the throttle valve.

Abstract: The invention is intended to simplify a default mechanism of a throttle valve opening and closing device for the purpose of improving mountability of the device to a vehicle. When a motor generate no driving forces, a throttle valve is held in a position (1) by a return spring. In this position, gaps are formed between the throttle valve and a wall surface of an intake passage. Spherical recesses are formed in parts of the wall surface of the intake passage. In a position (2) where the throttle valve is opposed to the spherical recesses, the gaps are minimized in an operating range of the throttle valve.

Abstract: A throttle control apparatus for an engine on a vehicle is provided, in which the number of component parts in the position detection means and the driven means is reduced to improve the accuracy in its position control and at the same time an integrated wiring is achieved and connectors are aggregated. The position detection means for detecting the position of a control valve, the driven means for controlling the position of the control valve, the means for processing control signals, an output from the position control means for controlling the position of the control valve are disposed within a sealed space defined by a body supporting a control valve shaft, and a cover. Based on the fact that the number of component parts of the position detection means may be reduced, the mechanical hysteresis and electrical hysteresis may also be reduced to improve the accuracy in controlling the control valve position, and it is possible to aggregate the connectors.
