CONSTRUCTION SPECIFICATIONS

CONNECTING RODS

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

PISTONS

The pistons in silicon aluminium alloy with self-heating inserts are subdivided into three size categories.An OMEGA-shaped combustion chamber in the piston crown improves combustion efficiency.There is a channel inside the piston 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 - Glow heater plugs4 - Air inlet5 - Exhaust gas outlet
