APPARATUS FOR ADJUSTING THE VENTILATION OF AN EXHAUST PIPE FOR A VEHICLE, ENABLING GAS DISCHARGE TO BE EFFICIENTLY CONTROLLED SINCE A SECOND OUTLET IS GRADUALLY OPENED AND A DISCHARGE PATH IS EXPANDED AS THE DISCHARGE PRESSURE OF EXHAUST INCREASES

摘要

PURPOSE: An apparatus for adjusting the ventilation of an exhaust pipe for a vehicle is provided to enhance gas discharge efficiency since the size of a discharge path of an exhaust pipe is controlled according to the discharge pressure of the exhaust gas, which is related to the RPM of a vehicle.;CONSTITUTION: An apparatus for adjusting the ventilation of an exhaust pipe for a vehicle comprises a first outlet(110), a second outlet(120) and an opening/closing part(130). The first outlet is installed in the exhaust pipe and discharges the exhaust gas from the vehicle. The second outlet is arranged on one side of the first outlet in the exhaust pipe, side by side. The opening/closing part is formed on the second outlet and the opening rate of the opening/closing part increases as the pressure of the exhaust gas increases. The second outlet is used as an additional discharge path of the exhaust gas. The first outlet has a venturi pipe shape, of which cross section becomes narrow with respect to the discharge direction of the exhaust gas.;COPYRIGHT KIPO 2011
