  • Patent number: 8096290
    Abstract: In an internal combustion engine, contaminated air in the crankcase creates problems. As a rule, the contaminated air is led into the engine's inlet manifold, and this can disrupt the smooth running of the engine. The invention eliminates the problem by having a filter connected to the crankcase, such that contaminated air from the crankcase must pass through this filter, where it is freed of its contaminants.
