Engines 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 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 of the base engine. Ten years ago, a compres-...

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 effective compression...
