    • PROBLEM TO BE SOLVED: To provide an intake device capable of measuring flow rate highly precisely when arranging at least either one side of bypass channel inlet and outlet of an intake amount measuring device biased toward the inside of a curve.SOLUTION: In an intake device 1, a channel which reaches an AFM 4 in a duct 3 from an element 7 of an air cleaner 2 is curved, when the direction becoming the inside of a curve is set as the inner circumferential side and the direction becoming the outside of the curve is set as the outer circumferential side, an AFM inlet 22 is located biased toward the inner circumferential side of the duct 3, and a straightening plate 30 which aligns a flow of intake air and guides the intake air into a bypass channel has a shape curved in such a direction that the flow direction of the intake air is changed, the curvature decreasing toward from the upstream side to the downstream side of the intake air. Thereby, in the channel from the element 7 to the AFM 4, the flow rate on the inner circumferential side increases according to the actuation of the straightening plate 30. As the result, even when the AFM inlet 22 is located biased toward the inner circumferential side of the duct 3, the flow rate can be measured highly precisely.
    • 要解决的问题:提供一种进气装置,其能够在将进气量测量装置的旁通通道入口和出口的至少任一侧至少偏向曲线内侧时精确地测量流量。解决方案:在进气装置 如图1所示,当从空气滤清器2的元件7到达管道3中的AFM 4的通道弯曲时,当将曲线内部的方向设定为内周侧和变为曲线外侧的方向时 被设定为外周侧,AFM入口22被定位成朝向管道3的内周侧偏置,并且将进气的排出并将进气引导到旁通通道的矫直板30具有弯曲的形状 在进气的流动方向改变的方向上,曲率从进气的上游侧向下游侧减小。 因此,在从元件7到AFM 4的通道中,根据矫正板30的动作,内周侧的流量增加。结果,即使当AFM入口22被偏置到内周面 可以高精度地测量流量。

    • PROBLEM TO BE SOLVED: To provide an engine fuel feed system having a speed density control system for fuel injection control which enables a predetermined person to easily recognize the clogging of an air cleaner when the air cleaner is clogged.
      SOLUTION: In this method of detecting the clogging of an air cleaner by an electronic control unit 10A which is an engine fuel injection control device in which the speed density control system is adopted to determine a fuel injection amount by predicting an intake air amount from the detected engine rotational speed and intake pipe pressure values, the difference between the averaged value and the minimum value of the intake pipe pressures which are continuously detected is calculated. When the difference is at least smaller than a predetermined clogging determination value, the air cleaner 2 is determined to be clogged, and a trouble code lamp 100 serving as a display means is lit.

    • PURPOSE:To easily detect choking of an air purifier irrespective of a fluctuation in the number of revolutions of an engine, by deciding whether the value of an intake air amount (the number of revolutions) and a negative pressure are higher or lower than their respective given values. CONSTITUTION:During the starting of an engine, when the number of revolutions of an engine is low, since a negative pressure in a suction pipe 4 is low, vacuum in a vacuum tank 17 is exerted on an actuator 13, and a valve element 7 decreases the area of an air intake pipe 2. When the number of revolutions is increased, a negative pressure in the suction pipe 4 is increased, vacuum in a vacuum tank 17 is released from a pressure control valve 14, an atmospheric pressure is exerted on the actuator 13, and the valve element 7 opens the air intake pipe 2. When a negative pressure in the suction pipe 4 is below a given value, the switch of the actuator 13 is turned ON, and when the number of revolutions of a sensor 25 for the number of revolutions is below a given value, a display part 32 is actuated.
