Introduction - ENGINE CRANKCASE

1.6 TS

CONSTRUCTION FEATURES

The engine block is cast iron, with high mechanical strength.

The crankshaft is supported by means of five main bearings (1).

The cylinders are formed directly in the engine block, and are graded into three sizes plus one oversize.

There are special channels in the engine block walls which allow the flow of coolant and lubricating oil.

At the bottom of each cylinder, there is a jet (2) from which oil is sprayed onto the piston crown to cool it and ensure the lubrication of the gudgeon pin.

CONSTRUCTION FEATURES

The engine block (3) is cast iron, with high mechanical strength.

The crankshaft is supported by means of five main bearings (1).

The cylinders are formed directly in the engine block, and are graded into three sizes plus one oversize.

The engine block also houses the two counter-rotating shafts, which are supported by a central bush and a ball bearing at the front and rear.

There are special channels in the engine block walls which allow the flow of coolant and lubricating oil.

At the bottom of each cylinder, there is a jet (2) from which oil is sprayed onto the piston crown to cool it and ensure the lubrication of the gudgeon pin.
