A Blow Off valve lets excess pressure escape from the intake tract of the engine to prevent excessive pressure and material fatigue. In tuning enthusiasts, however, the main focus is on the striking noise during load change, which has become known from scene films. This noise is generated when the pressure generated in the intake tract by the turbocharger is discharged by this valve.

The Blow Off valve is distinguished between closed and open models. In the closed variant, the air discharged through the valve is not returned to the outside into the atmosphere, but to the suction tract before the turbocharger. In the open variant, the air is guided directly into the atmosphere when leaving. This results in the known cliche.

A friend of mine once had a Smart Diesel (no joke) with an open BlowOff valve and you’ve heard that well. Of course, this is completely illegal.

But at least the conversion does not change the classification of pollutants, does it?
