What’s the boost pressure on a Mercedes Benz Turbo?

The reason for this is very simple the turbo is spinning at 2750 rps (per second) at normal boost pressures and flow rates (not maximum) rpms translate to approx 165,000 per minute. The micro sensor for boost pressure is capable of up to 500 samplings per second due to the extremely rapid response of the VNT type turbos.

How does the diesel fuel system keep air out?

The diesel fuel system is designed to keep air out of the fuel system by keeping the entire system full of diesel at all times. Air can get into the fuel system after a fuel filter change or if the vehicle runs out of diesel.

However, if the engine is not running correctly automatic regeneration will not be started.
