INNOVATION WITH LIGHTNESS

WHY TO CHOOSE The 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 built for 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 the STEYR MONOBLOCK engines achieve a unique image with vehicle manufacturers and operators around the world. 6-CYLINDER4-CYLINDER The STEYR MONOBLOCK is a highly efficientsingle casting from special high tensile alloy. Thedesign shows a “free liner”, with a uniform and most effective cooling jacket, valve seats from“Stellit” material, inserted valve guides. Due tothe fact that the design is free from high torque cylinder head bolts and cylinder head gasket there is no deformation to the roundness of thecylinders, no extra stress from differenttemperature levels.Just a MONOBLOCK design offers an unlimitedflow of cooling water and to provide a uniform and effective cooling in the most critical uppersection of the cylinder liner while conventionalcylinderblock / cylinderhead – design always result in “hot spots”, extra stress due to differenttemperature levels and cylinderhead bolts… Durability, Safety, robust Cooling behaviour were the guidelines of the design and led us to thisunrivalled product range of compact High Speed Diesels.The STEYR MONOBLOCK engine family isequipped with a high pressure STEYR UnitInjector with two stage injection nozzle and upto 2000 bar injection pressure. Design and material selection have been specifically matched to operate the engines with many types andqualities of diesel fuels like Diesel (F54, EN 590ff),Kerosene (JP8 / F34) or Maritime Diesel fuel.
