摘要： A throttle valve linkage for use with a multi-carburetor assembly comprising a pair of carburetors has first and second levers secured respectively to the throttle shafts of the first and second carburetors, first and second link members respectively connected at one ends to the free ends of the first and second levers. The other ends of the first and second link members are pivotally connected by a common pivot pin which is slidably movable in a guide channel. The rotation of the first carburetor throttle shaft is transmitted by the linkage to the second carburetor throttle shaft so that the latter is rotated in a direction opposite to the direction of rotation of the first carburetor throttle shaft.

摘要： An intake air flow sensor comprises a sensor main body and a connection unit main body, the former consisting of a main passage for passing intake air and a bypass passage for bypassing part of the air flowing through the main passage and joining it again to the air of the main passage. An intake air flow meter is disposed in the bypass passage to measure the intake air quantity. The bypass passage has an opening which opens to the main passage. A ring is fitted into the main passage of the sensor main body in such a manner as to close part of the opening of the bypass passage. An insulator is clamped by the ring and the connection unit main body. According to this construction, the area of the opening of the bypass passage to the main passage is not changed due to deformation of an insulator when the insulator is interposed between the sensor main body and the connection main body and they are fixed together by bolts.
