Crankcase ventilation system

The purpose of the crankcase ventilation is to evacuate gases from the crankcase in order to
keep the pressure in the crankcase within acceptable limits.
Each engine must have its own vent pipe into open air. The crankcase ventilation pipes may
not be combined with other ventilation pipes, e.g. vent pipes from the system oil tank.
The diameter of the pipe shall be large enough to avoid excessive back pressure. Other possible
equipment in the piping must also be designed and dimensioned to avoid excessive flow
resistance.
A condensate trap must be fitted on the vent pipe near the engine.
The connection between engine and pipe is to be flexible.
