Manufacturing technology ROTO 85 FSI
- Crank case (kit) – it is rough-worked of the cast at the CNC milling cutter. After that it is covered or slashed with a special colour.
- Cylinder (roll) – it is made of one piece of dural with pressed insole from the mild-granular cast iron, it is sharpened and honed to the correct size.
- Piston – it is casted from silicon alloy with one sealing circle. The aparature for the bung 8 mm is honed.
- Piston rod – it is forging, which is completely worked. Two needle focuses are moulded into piston rod, it is made for the piston and cranked bung.
- Crank shaft – it is made of one piece of steel, it is cemented and hardened and it is completely sharpened.
- Back lid of the engine – it is worked casting, in which is hardened and sharpened rolled slide - valve layed.
Pieces of engine are after clearing by the scan pieced together in preparations at the special workplace.- Crank case (kit) – it is rough-worked of the cast at the CNC milling cutter. After that it is covered or slashed with a special colour.
