TBO 24,000 hours deployed in the MTU 4000 series and allows the independent determination of all injection parameters, resulting in reduced fuel consumption and emis- sions.

Another characteristic of the 8000 series is the sequential turbo charging, which is an optional feature. The tech- nology is designed to considerably help supercharged engines to achieve a wide performance map, thus good accelera- tion while keeping fuel consumption and smoke levels low. With sequential turbo charging, individual exhaust turbocharg- ers can be switched on and off during operation, depending on the engine's power demand.

All engines of the Series 8000 are con- trolled and monitored by the electronic engine management system MDEC.

The system is designed to optimize all engine functions, and the engine can be included in an overall controlling and monitoring concept of the entire propul- sion system and other areas of the ship.

The reported drive in developing the 8000 was an overall reduction of life cycle costs through the reduction of fuel consumption and maintenance costs. For example, when deployed in a fast com-

Main bearing cap mercial ship application, the fuel con- sumed by the 20V 8000 lies, over a wide operating range, below 195 g/kWh. At its best performance, it remains below 190 g/kWh, while always keeping with- in IMO limits for NOx.

On the maintenance side, intervals between the engine main overhauls are set at 24,000 hours for fast commercial vessels. When maintenance is needed, time spent working on the powerplant is minimized by the fact that all compo- nents subject to maintenance routines have been placed into a so-called service block at the free end of the engine.
