SURGE TANK OF INTERNAL COMBUSTION ENGINE AND INTAKE MANIFOLD

PROBLEM TO BE SOLVED: To provide a surge tank of an internal combustion engine in which a pressure sensor can be fitted without increasing the number of parts and assembling man-hours and which can eliminate the effect of a purge gas introduction part even if the purge gas introduction part is provided thereto, and to provide an intake manifold having the surge tank. SOLUTION: A first partition wall 19 and a second partition wall 24 extend toward the openings 14a, 15a of a manifold body 14 and a tank cover 15. A cylindrical part 33 into which the detection part 20b of the pressure sensor 20 is inserted is so formed that an undercut is not formed therein. A room 26 communicating with an intake air introduction port 18 and an intake air supply port 23 sides through an air passage 25 are formed of the first partition wall 19 and the second partition wall 24. The intake air pressure in the room 26 is detected with the pressure sensor 20. COPYRIGHT: (C)2010,JPO&INPIT
