8. Cylinder Block

The cylinder block is made of aluminum die casting. Its open-deck design provides it with such

advantageous features as relatively small weight, high rigidity and excellent cooling efficiency.

The cylinder liners are made of cast iron. They are dry type which means their outer surfaces

are entirely in contact with the cylinder block.

The cylinder block supports the crankshaft at its five journals. The journal supporting portions

are designed such that sufficient stiffness and quiet operation are ensured.

The oil pump is located in the front center of the cylinder block and the engine coolant pump is

located at the front of the left-cylinder bank. At the rear of the right-cylinder bank is an oil separator

which removes oil mist contained in blow-by gas.
