How It Works 101
Driving a turbo car is a fun experience. The acceleration boost from the turbo is quite thrilling. Anyone who’s driven or owns a turbo car will understand. But, did you ever wonder why a turbo makes an air release sound when releasing the gas? That sound is usually a blow-off or diverter valve. Per this article, the focus will be solely on the diverter valve concept. So, how does a diverter valve work with a turbo?
Breakdown of Diverter Valve Functionality
A diverter valve is a manifold vacuum-actuated valve that releases pressure into the intake system on turbo engines. This valve is also known as a compressor bypass valve (CBV) or a pressure relief valve. Furthermore, the valve release occurs during the lifting or closing of the throttle. Hence, while accelerating and then releasing the throttle, the car makes an air sound. This sound is the air pressure releasing into the intake. Many turbo enthusiasts love this sound, just as a supercharger fans enjoys the high-rev whining. By sending the air back into the intake, it overall benefits the performance of the vehicle. Even if it is only a slight boost in power, every bit counts.
Vroom! Hiss! Vroom! Hiss!
Well, hopefully this article helps the reader understand the purpose of a diverter valve. Any vehicle with a turbo has some form of a blow-off valve. And, each one functions differently. Manufacturers such as Audi and VW use diverter valves in their vehicles. Furthermore, Aftermarket diverter valves are a great addition to a turbo vehicle. But, first, always ensure the valve fits the specific model. Buying the wrong valve may lead to lost time and longer wait periods. In conclusion, the diverter valve is a piece of technology that offers a way to be energy efficient.
