CONSTRUCTION SPECIFICATIONS

CONNECTING RODS

The connecting rods are in hardened and tempered steel with a copper bush (1) fitted for matching with the piston gudgeon pin (2).The floating pins are held in place by two expansion rings (3) that are housed in grooves on the piston hubs.

PISTONS

The silicon light alloy pistons with autothermic inserts are subdivided into three size categoriesAn OMEGA-shaped combustion chamber in the piston crown improves combustion efficiency.There is a channel inside the gudgeon pin through which the oil, sent by the jets, flows, ensuring improved piston cooling.The piston is coupled to the pin by means of two copper alloy bushes.1 - Piston2 - Injector3 - Heater plugs4 - Air inlet5 - Exhaust gas outlet
