Title:
吸気制御装置
Document Type and Number:
Japanese Patent JP6968636
Kind Code:
B2
Abstract:
To provide an intake control device which can introduce intake pressure in an intake pipe into an intake pressure sensor without the need of using a pressure introduction pipe.SOLUTION: An intake control device 1 comprises: a body 4 integrally having intake pipes 2a, 2b and a connection part 3; and an intake pressure sensor 7 for measuring intake pressure on a downstream side of the intake pipes 2a, 2b. The body 4 comprises: an intake pressure detection pipe 9 communicating with a detection part of the intake pressure sensor 7; linear intake pressure introduction pipes 10a, 10b passing through the inside of the connection part 3, and communicating with the intake pressure detection pipe 9; a purge first passage 11 connected with a conduit communicating with a canister; and a linear purge second passage passing through the inside of the connection part 3, and communicating with the purge first passage 11. The purge second passages 12a, 12b are parallel with the intake pressure introduction pipes 10a, 10b.SELECTED DRAWING: Figure 1
