Many modern large slow speed diesel engines used for main propulsion operate with a so called constant pressure turbocharging system. What is meant by constant pressure when used to describe such a turbocharging system?

Pressure variations in the scavenge air supply are avoided by supplementing the air supply with air from the auxiliary blowers so keeping a constant pressure across the load and speed range.

Pressure variations at the turbocharger inlet are damped out due to the large volume of the exhaust receiver and the short lengths of pipe from individual cylinders.

The exhaust pipes from groups of three cylinders are joined together before entry into the turbocharger so that the exhaust pulses from each cylinder cancel each other giving a constant inlet pressure.

The exhaust gas pressure is maintained constant by using a bypass waste gate to dump excess pressure at high engine loads.
