CYLINDER BLOCK CONSTRUCTION [MZR-CD (RF Turbo)]

id0110f1100500
• A special cast iron liner-less type cylinder block has been adopted to provide a thin-walled cylinder block. In addition, a curve-shaped, deep-skirt cylinder block has been adopted to heighten the cylinder block rigidity.
• The engine coolant passage has been equipped by cross-drilling in the bore, improving the cooling performance and reducing oil consumption.
