ENGINE BLOCK

This is a single block in iron with a high mechanical resistance.

The crankshaft is supported by five main supports which also house the same number of bearing halves with thin shells.

The cylinder liners are the integral type. Grooving in the walls of the block allow circulation of engine coolant and lubricating oil.
