Definitions

  • the present invention has a first feature in that, in addition to the ninth or tenth feature, the device block is made of a synthetic resin.
  • the intermediate portion of the bypass can be formed simultaneously with the molding of the device block made of synthetic resin, and the production time can be reduced.
  • the use of synthetic resin device blocks, which are light in weight and weight, can reduce the overall weight of the intake system. It should be noted that the above operation corresponds to step mode 28 in an embodiment of the present invention described later, and the output of the throttle sensor corresponds to the pickup coil 8b.
  • the bypass intermediate part 15m of the device block 11 faces the mounting surface 10a so as to communicate with the bypass inlet hole 15i and the bypass outlet hole 15o, respectively.
  • the upstream groove 16 is arranged inclined in the vertical direction, the bypass inlet hole 15 i opens at the lower end (see Fig. 7), and the through hole 18 opens at the upper end. .
  • the downstream groove 17 is longer than the upstream groove 16, extends substantially horizontally from the valve guide hole 19, and bends downward from the middle thereof, and has a bypass outlet hole 15 at its lower end. o opens.
  • the metering hole 20 is disposed above the bypass inlet hole 15i and the outlet hole 15o and on the inlet side of the intake passage 2. Therefore, even when the intake passage 2 is arranged horizontally as shown in the figure, or when the entrance of the intake passage 2 is directed upward, the measurement holes 20 are the bypass inlet holes 15i and the bypass outlet holes 15i. occupy the upper position of o Will be.
  • the bypass passage 15 has a shape that always descends toward the bypass inlet hole 15i and the bypass outlet hole 15o, with the measurement hole 20 at the top.
