PROPULSION UPDATE

MaK Presents New Long-Stroke Engine

The release of the M43 marine diesel engine from the German manufacturer MaK marks the fourth series in the engine makers new generation of long-stroke engines.

The engines of the M43 series will cover the power and cylinder ranges from where the M32 series left off and will be available in six, seven, eight and nine-cylinder in- line versions. Also, the 12, 14, 16 and 18-cylinder V configurations will cover output ranges from 10,800 to 16,200 kW. The M43 series features many advances in design principles since the M series was first manufactured in 1992 with the M20, M25 and M32.

Among the new features are a high stroke-bore ratio of 1.4, a 900 kW/cylinder output, fuel consump- tion of 175 g/kWh at 0.6 g/kWh lubricating oil consumption and long overhaul intervals for wearing parts. In addition, IMO require- ments of NOx reduction are met by means of a high-compression ratio and a corresponding firing pres- sure at attendant low consumption.

The overall range of application of these new MaK engines is intended to be versatile.

The in-line engines are designed mainly for marine applications, covering all essential ship types from multi-purpose to special-pur- pose ships; while the V-engine is suited for passenger ships.
