PROCEDE POUR LA PREPARATION DES DERIVES ORGANOPHOSPHORIQUES

摘要

The ventilation system for an internal combustion engine comprises an oil separator (2) with a pre-cleaning device (3) and a downstream positioned main separator (4). The pre-cleaning device (3) is fitted with a diffuser inserted between an inlet (7) and an outlet (10) expanding in the direction of the flow. The pre-cleaning device (3) and the main oil separator (4) are made all of a piece, preferably forming a separator unit (2). Independent claims are given for an internal combustion engine with a connection duct between each cylinder with the cooling cover of the crankcase, a poly-v pulley, and an internal combustion engine with a control duct connected to the main oil duct of the engine.
