5 With a long maritime tradition and the sound basis of a leading engine manufacturer DEUTZ engines have an international reputation as reliable, durable and efficient propulsion units for work boats as well as commercial vessels and their auxiliary drives. The requirements of the engines for the main and auxiliary drives of ships vary. But the key expectations are quite simple: Economy and availability are of the most important for every application. Technically mature and state-of-the-art in engine development, our engines offer the security and reliability in everyday use that our customers demand. DEUTZ drives also set high standards where economy is concerned. Because in addition to state-of-the-art engine construction criteria and a practical design our drives also feature an exemplary cost/benefit ratio. Great economic values and excellent exhaust gas emissions for the benefit of the environment are all part of the DEUTZ standard. In order to strengthen our customers position in the maritime sector we have concentrated on the field of compact engines for marine propulsion and auxiliary drives. The 1015M series reflects the engine manufacturer know-how of DEUTZ in marine applications.

6 Modern water-cooled, four-stroke, 6 and 8-cylinder engines in V configuration water-cooled turbocharger and exhaust manifold gear-driven power take-offs modern injection system with mechanical speed governor electronic speed governor for genset drives charge air cooling by engine coolant innovative multi-parallel cooling system compact dimensions Low maintenance costs due to heat exchanger as plate cooler. The innovative cooling system reduces the fuel consumption and is a further example of the high reliability. Low noise emissions eliminate complex attennation. High reliability and durability due to integrated pipes. Classification by all leading classification societies. All engines comply with IMO regulations; engines with charge air cooler (MC engine types) comply with ZKR II, EU stage II (2004/26/EG) and US-EPA Marine Tier 2. The particle emissions in the MC engine types fall 30 % below the limit value specified in the ZKR II. Type of cooling: Crankcase: Crankcase breather: Cylinder head: Valve arrangement/ control: Piston: Piston cooling: Con rod: single-circuit mixture cooling as indirect cooling (DEUTZ Multi-Parallel Cooling system) in raw water cooling with built-on plate heat exchanger, circulation coolant pump, compensation tank, thermostat and raw water pump. In keel cooling with coolant circulation pump and integrated thermostat. Integrated compensation tank as an option cast iron crankcase with replacable wet liners closed version, vacuum-pressure regulator single cylinder heads of cast iron in cross flow version hanging in the cylinder, four valves per cylinder, actuated by tappets, push rods and rocker arms, driven by gears and central camshaft three-ring aluminium piston with cooling channel and ring carrier for the top ring groove by cooling oil by means of spray nozzles drop-forged steel Crankshaft: drop-forged steel, with bolted on counterweights, V6 with split pins offset 30 Crankshaft and big end bearing: Camshaft: Turbocharging: Exhaust manifold: Rotary vibration damper: Lubricating system: optional Injection pump/ controller: Injection lines: Fuel system: Generator: Starter: Heater: Range of variants: tri-metal plain bearing steel camshaft two water-cooled turbochargers and poss. charge air cooler on the flywheel side water-cooled exhaust manifold viscosity vibration damper forced-feed lubrication with gear pumps, lubricating oil cooler integrated in the engine, paper fine filter as exchangeable cartridge in the main lubricating oil stream, duplex change over filter in-line fuel injector with mechanical (for variable speed) or electronic (for genset) controller double walled injection lines for high pressure lines as an option mechanical piston pump, exchangeable cartridge for fuel filter, optional duplex change over filter three-phase current generator 28 V / 55 or 80 Ampere 24 V/5,4 kw connection possibility for heater or hot water boiler to the engine cooling circuit hydraulic pumps, flywheels, connection housing SAE 1 standard, oil pans, air filters, engine feet with elastic mounts, starters, generators, engine control system, ship gear
