Cleaning arrangement for turbocharger turbines

The engine has parallel exhaust turbo chargers, at least one of which can be switched to idling operation. Each working bank (3,4) of the V-type engine (1) has separate charging air and exhaust air collection pipes (7,8,5,6) with associated turbochargers (9,10) for thermodynamic separation. Each bank also has fuel supply reduced to idling operation. The charging air pipes are formed as a common pipe with dividing wall. The fuel supply to each working bank is adjusted to idling operation via pump stop cylinders of the injection pumps.
