DEVICE AND METHOD FOR AN EXHAUST SYSTEM OF A MOTOR VEHICLE

摘要

A device for an exhaust system of a motor vehicle includes baffle wall, a passage, and a body having a sidewall with an exhaust conduit extending therethrough. The baffle wall has a bore in fluid communication with the exhaust conduit. The baffle wall extends from the sidewall and into the exhaust conduit for directing the flow of exhaust gas through the bore and increasing a speed of the flow of the exhaust gas. The passage extends through the sidewall of the body for fluid communication between the bore and an ambient environment. As such, the increased speed of the flow of the exhaust reduces the pressure and creates a venturi for drawing cool ambient gas into the flow of the hot exhaust gas. In addition to the venturi, the bore and the passage collectively generate a desirable engine exhaust sound when the flow of the exhaust gas passes therethrough.

1. A device for an exhaust system of a motor vehicle, the exhaust system including an exhaust pipe for receiving a flow of exhaust gas from an engine of the motor vehicle and discharging the flow of exhaust gas into an ambient environment, the device comprising;
a body having a sidewall and an exhaust conduit extending therethrough; a baffle wall having at least one bore, the at least one bore in fluid communication with the exhaust conduit extending therethrough for increasing a speed of the flow of exhaust gas through the bore; and a passage extending through the sidewall of the body from the ambient environment to the bore for fluid communication therebetween, wherein the bore and the passage are configured to generate a venturi and draw cooler ambient gas through the passage and into the bore.
