Description:Cat® Exhaust Venturi Pipe in exhaust system is a device that uses the venturi effect to create a low-pressure zone in the exhaust pipe, which draws in fresh air and reduces the back pressure and noise of the exhaust system. The venturi pipe consists of a converging nozzle, a throat, and a diverging diffuser, and can be adjusted to vary the flow rate and pressure of the exhaust gas. A venturi pipe can also be used to recirculate some of the exhaust gas back into the engine, which reduces the emissions and improves the fuel efficiency. Each Cat® Pipe utilizes superior materials and processes, fabricated specifically to withstand the application’s pressure and flow requirements which will ensure a long life and proper machine functionality. Engineered with a specific application in mind, every Cat® Pipe is designed and manufactured to exacting tolerances to ensure proper alignment with existing systems on your Cat® Machine.Application:Cat® Exhaust Venturi Pipe is used in exhaust systems of Cat machines.
