Scania DC12 Cylinder Block

The Scania DC12 cylinder block is the core base component of DC12 inline six-cylinder heavy-duty diesel engine, widely matched to Scania series tractors, intercity passenger coaches and heavy cargo trucks. It meets aftermarket maintenance and direct replacement demands for fleets equipped with Euro III/Euro IV/Euro V DC12 power units.

Built upon mature Scania heavy-duty diesel engine design, this cylinder block adopts high-strength gray cast iron casting technology. Optimized internal cooling water galleries and lubricating oil passages improve heat dissipation efficiency and smooth oil circulation, effectively lowering wear risk of moving assemblies and maintaining stable continuous operation under heavy loads.
