Flame Trap

The flame trap roughly separates the crankcase gases from the cylinder block. The crankcase gases circulate around the walls in the flame trap before entering the cyclone separators. The cyclone separators act on the crankcase gases to separate the particles/substances. The oil in the crankcase gas runs down into a container chamber to be returned to the oil pan. The rest of the crankcase gas is directed on to a pressure regulator which regulates the pressure in the crankcase. The crankcase gas is then evacuated from the pressure regulator to return to the intake manifold via the turbocharger on vehicles with turbocharged engines. Otherwise the gas returns directly to the intake manifold.
