STEYR MONOBLOCK DIESELMARINE ENGINE SERIES

The STEYR MONOBLOCK is a highly efficientsingle casting from special high tensile alloy. Thedesign shows a “free liner”, with a uniform andmost effective cooling jacket, valve seats from“Stellit” material, inserted valve guides. Due tothe fact that the design is free from high torquecylinder head bolts and cylinder head gasketthere is no deformation to the roundness of thecylinders, no extra stress from differenttemperature levels.

Only a MONOBLOCK design offers an unlimitedflow of cooling water to provide a uniform andeffective cooling in the most critical upper sectionof the cylinder line, while conventionalcylinderblock / cylinderhead – design alwaysresult in “hot spots” and extra stress due todifferent temperature levels and cylinderheadbolts.

Durability, Safety, robust Cooling behaviour werethe guidelines of the design and led us to thisunrivalled product range of compact High SpeedDiesels.

The STEYR MONOBLOCK engine family isequipped with a high pressure STEYR UnitInjector with two stage injection nozzle and upto 2000 bar injection pressure. Design andmaterial selection have been specifically matchedto operate the engines with many types andqualities of diesel fuels like Diesel (F54, EN 590ff),Kerosene (JP8 / F34) or Maritime Diesel fuel.

02 STEYR MONOBLOCK DIESEL

WHY TO CHOOSEThe STEYR MONOBLOCK engine family consists of several design solutions which are the key for highest powerdensity, reliability and safety in operation under all operational profiles and environments. The engines are builtfor special applications like Military and Light Commercial vehicles, Marine applications and Stationary power plants.Due to the exceptional robust cooling behaviour and the reliable operation even with poor fuel qualities theSTEYR MONOBLOCK engines achieve a unique image with vehicle manufacturers and operators around the world.

INNOVAT ION W ITH L I GHTNESS

The environmentally friendly HYBRID SOLUTION marks a new chapterin the history of pleasure boat propulsion systems. It not only assureszero emission and low speed manoeuvring in harbours, noiseless driveon inland waters and nature reserves, but also eliminates the need forseparate generator units for other onboard equipment. The “zeroemission” electric drive mode allows a speed of 5 knots using solelyelectric propulsion and switches to the combustion engine with an easyturn of the ignition key.

The ingenious propulsion then gets “boosted” by the electric drive andenables quicker acceleration, lowering fuel consumption, improvingresponse and dynamics. Significantly reduced maintenance costs andimproved ease of service are further irrevocable arguments that STEYRMOTORS is introducing a serious technological novelty.

WORLDWIDE FIRST SERIALIZEDHYBRID PROPULSION SYSTEM FOR PLEASURE BOATS

STARTER MODEThe conventional starter motor can be eliminated.

GENERATOR MODEIn Generator Mode, the extended battery pack is optimised and charged.

ELECTRIC CRUISE MODENo emission, no noise.

BOOST MODEAn improved response of the drive unit occurs through the boost mode.
