The Deutz marine engine programme currently comprises six series with power ratings between 14 and 440kW. All engines are available as classified units and can be supplied with different cooling systems depending on the relevant operating conditions.
The two and three-cylinder engines of the 203 series (bore/stroke 100/105mm) are positioned at the lower end of the program with power ratings between 14 and 56kW at speeds between 1,500 and 3,000rpm. Wet cylinder liners and unit cylinder heads characterise these robust, durable engines, which have proved their worth not only in yachts, but also in small fishing craft and rescue boats. In the case of an emergency, they can even be started manually. A special version with SOLAS certificate is available for the propulsion of rescue boats.
In combination with rudder propellers the air-cooled diesel engines of the 912 and 913 series have proved as propulsion units for ferries. In addition, numerous applications exist as drive units for harbour sets of larger vessels. Their low fuel consumption is exemplary and they are unrivalled with regards to their low exhaust emission values. Their integrated cooling system as well as low weight and compactness make installation very simple.
The engines of the 912 series (bore/stroke 100/120mm) cover as naturally aspirated models with three, four, five and six cylinders and the power ranges from 24 to 78kW. The speeds extend from 1,500 to 2,300rpm. In the case of the 913 series, there are available in addition to the naturally aspirated units with three, four and six cylinders, and also turbocharged six-cylinder engines with or without charge air-cooling. The power range spans 25 to 142kW at speeds between 1,500 and 2,300rpm.
The lower Deutz engine power range also includes the water-cooled in-line engines of the 229 series (bore/stroke 102/120mm) with power ratings between 34 and 115kW at speeds between 1,500 and 3,000rpm. The four and six-cylinder engines are available as naturally aspirated or turbocharged units. Here too, a long engine life is ensured by wet cylinder liners and unit cylinder heads.
The medium power range is covered by water-cooled in-line 1013 series engines (bore/stroke 108/130mm), which are also equipped with wet cylinder liners. Exhaust manifold, turbocharger and charge air cooler of these four and six-cylinder engines are water-cooled. Their power range extends from 70 to 195kW at speeds between 1,500 and 2,300rpm.
A high-pressure injection system with unit injection pumps (PLD) ensures low fuel consumption. With regard to the exhaust emissions, these engines are certified in accordance with IMO, RschUO and US-EPA.
The V-engines of the 1015 series (bore/stroke 132/145mm), having been well established as marine propulsion units, complement the Deutz engine range at the upper end with power ratings between 203 and 440kW. The rated speeds of the turbocharged six and eight-cylinder models are between 1,500 and 2,100rpm. The exhaust manifold and turbocharger of these engines are also water-cooled. In the case of the engine versions with charge air cooler this is integrated in the engine cooling circuit. Marine main propulsion engines are provided with a mechanical governor, whereas onboard gensets feature an electronic governor. On request, double-walled injection lines are available.
These short V-engines with PTOs for different applications via the gear train feature numerous installation benefits. Low fuel and lube oil consumption figures and the heat exchanger designed as plate-type cooler permit minimum operating cost. They, too, are certified in accordance with IMO, RschUO and US-EPA.
