Air circulated in the interior of a gasoline engine is mixed with gasoline and oil vapors trapped in the crankcase (15). The vapors are then fed, by means of intake manifold vacuum to the cylinders for combustion, by passing through a PCV valve. A PCV charcoal hose (30) containing activated charcoal particles (26) is connected to the crankcase (15) and extending to the intake manifold (18) for absorbing and storing the crankcase vapors when there is no vacuum or when the PCV valve is restricting the flow therethrough. These vapors will be drawn into the intake manifold (18) when circulated air is flowing over the charcoal (26). This action clears the charcoal and renews its storage capacity. |
