Monoblock diesel

Hello, doing some searches on other things I came across this monoblock engine design. Not much knowledge in this department myself or in boats in general, just thought this design is pretty kool.

Steyr Marine
source below:

The STEYR MONOBLOCK DIESEL engine family consists of several design solutions which are the key for highest power density, reliability and safety in operation under all operational profiles and environments. The engines are specifically designed and built for Marine applications. Due to the exceptional robust cooling behavior and the reliable operation even with poor fuel qualities the STEYR MONOBLOCK engines achieved a unique image with boat manufacturers and operators around the world.

The STEYR MONOBLOCK DIESEL is a highly efficient single casting from special high tensile alloy. The design shows a "free liner", with a uniform and most effective cooling jacket, valve seats from "Stellit" material, inserted valve guides. Due to the fact that the design is free from high torque cylinder head bolts and gasket there is no deformation to the roundness of the cylinders, no extra stress from different temperature levels.

Only a STEYR MONOBLOCK DIESEL design offers an unlimited flow of cooling water to provide a uniform and effective cooling in the most critical upper section of the cylinder line, while conventional cylinderblock / cylinderhead - design always result in "hot spots" and extra stress due to different temperature levels and pre-stress from cylinderhead bolts.

Durablity, safety and robust cooling behaviour were the guidlines of the design and led us to this unrivalled product range of compact High Speed Diesels.

The STEYR MONOBLOCK engine family is equipped with a high pressure STEYR Unit Injector with two stage injection nozzle and up to 2000 bar injection pressure. Design and material selection have been especially matched to operate the engines with many types and qualities of fuels like Diesel (F54, EN 590ff), Kerosene (JP8 / F34) or Maritime Diesel fuel.
