Abstract
PURPOSE: To stabilize the Karman vortex and reduce the pressure loss of sucked air, by providing the Karman vortex flow meter in the detection duct having an approximately angular section fixed to the straight tube part of the air suction tube.
CONSTITUTION: Detection duct 13 having an approximately angular section is fixed to straight tube duct 10 constituting a part of the air suction tube by arm 11 so that center lines of both ducts may agree with each other, and vortex generating material 14 for Karman vortex flow meter and heat coil 15 of a vortex detector are provided in duct 13. Therefore, since the distance between vortex generating material 14 and the wall face of duct 13 can be 3W4 times as long as the width of the vortex generating material, generation of Karman vortex can be stabilized and increment of pressure loss for the maximum air suction quantity of the engine can be suppressed. Further, since it is unnecessary to give the angular section to the air suction tube itself, it is unnecessary to increase the length of the detecting part for the purpose of preventing flow disturbance, and reduction of the number of degrees of freedom for mounting of the detector is prevented.
