Monoblock Design

STEYR MOTORS marine diesel and automotive engines are produced using a unique Monoblock design where the engine block and cylinder head are manufactured into one piece.

Using high grade alloy cast iron, the Monoblock ensures even temperature and cooling providing exceptional life for the liner. In doing this, STEYR MOTORS successfully reduces the common issues around marine engines being blown head gaskets

Combined this with Chrome Molybdenum forged crankshafts, dynamically balanced pistons cast from high silicon aluminium, ceramic coated top rings and hardened valve seats and you have an engine that is robust and capable in any environment.
