Title:
MUFFLER FOR AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2013/069851
Kind Code:
A1
Abstract:
The present invention pertains to a device for the pressure calibration of exhaust gas and torque output, wherein the fluctuation pressure of exhaust gas which is discharged via an exhaust device is calibrated for increasing the torque output of an engine while the change of exhaust pressure due to the difference of static pressure and negative pressure that is generated when pistons operate is controlled for increasing the running performance of an automobile, saving fuel, and promoting the discharge of exhaust gas.
An induction member (10) of the above-mentioned present invention comprises:
a spiral induction piece (11) made from a metal plate in the shape of a cross and connected to an exhaust pipe (4) between a catalyst converter (2) of an exhaust system which discharges exhaust gas discharged from an engine (1) and a sub muffler (3); a cylindrical coupling member (12) is coupled to one side of the induction piece (11) by welding and has a protrusion portion (12a) and a fitting portion (12b) for connecting the same to the exhaust pipe (4); an induction rod (14) is welded at one side of the cylindrical coupling member (12); and upper and lower and right and left slanted surfaces (11a) are respectively formed so as to protrude at an acute angle at both sides of the induction piece (11), wherein the exhaust pipe (4) is fitted into the fitting portion (12b) of the induction member (10).
