Ventilation system ProVent®

In internal combustion engines, an oil-laden leakage gas known as the blow-by is produced in the crankcase.The blow-by must be returned during the combustion process, which is achieved by closed crankcase ventilation (CCV) systems. CCV systems also separate and return the oil to the crankcase and regulate pressure in the crankcase.MANN+HUMMEL can supply all the components and systems involved in crankcase ventilation, including: Oil separators Pressure regulating valves Heating pipes Valve technology (anti-drain valves, PCV valves, ventilation valves) Integration of crankcase ventilation into cylinder head covers or other integrated solutionsWith increasingly strict emissions legislation, the requirements for oil separation have increased continually over the past few years. Emissions-related engine components such as exhaust turbo chargers, charge air coolers and charge air sensors must be protected against performance degradation from oil contamination. MANN+HUMMEL provides various designs for oil separation, ranging from inserted or non-inserted inertial separators, such as cyclonic or impactor separators, to the ProVent fibre separator for HGV and industrial use.
