Low Emission Engine already in operation Back in 2000, Caterpillar Motoren identi- fied three emission levels for the MaK marine product in order to cope with short to midterm emission regulations. These were a base line IMO engine, which fulfils MARPOL 73/78, Annex VI, an IMO-compli- ant engine with invisible smoke emissions and a Low Emission Engine (LEE) which meets the expected N0X emission range of IMO II and is also invisible in smoke. In addition, this strategy favours inside- the-engine means because of their clear advantage with respect to cost, complex- to increase the compression ratio...

Flex Cam Technology FCT (schematic diagram) Building upon the Emission Reduction System integration concept, FCT achieves synergy between flexible fuel systems and advanced air systems with maximum utilization of the current engine design. While maintaining high fuel injection pressure over the whole operating range, fuel injection and inlet valve timing are load controlled and influenced by a lever shaft which affects injection timing/ pressure and inlet valve events. Valve timing changes at part load to raise effec- tive compression and enhance complete combustion. In addition, shifting the...
