Camshafts

The camshafts are components formed by an axis and a series of cams that have the important function of performing the precise opening/synchronization of the intake and the exhaust valves in the combustion chamber.

Benefits of RIO camshafts

  • Original quality, according to the specifications of each engine design.
  • They attend the most demanding machining standards.
  • In gray or nodular cast iron with thermal treatments on the cams.

Camshafts application

The camshafts are described as:

  • SOHC – Installed on the cylinder head (simple control), common in the Otto cycle and some diesel generations.
  • DOHC – Installed in the cylinder head (double control), common in the Otto cycle and some diesel generations.
  • OHV – Installed in the block, common in the diesel line application.

Did you know?

The perfect operation and durability of the valve camshaft depends on:

  • the alignment of bearings;
  • the axial clearance of the valve train;
  • poor lubrication;
  • combined exchange (command + tappet)
  • the use of good quality components (rings, plain bearing, and others).
