  • Patent number: 6230698
    Abstract: An engine pollutant filter system for providing cleaner exhaust and more massive power strokes. The engine pollutant filter system includes an engine having a positive crankshaft ventilation, a container member containing water and having a sealed cap with an intake port and an outlet port extending therethrough, and also includes a first hose member extending into the water container member and connected to the positive crankshaft ventilation of the engine, and further includes a second hose member connected to the outlet port and connected to the carburetor/fuel injector body. Steam mixture from the container member is drawn into the engine thus producing a cleaner burn, a cleaner exhaust and a massive power stroke due to the buildup of pressure effected by the heating of the steam mixture. In addition, a third hose is connected to the second hose and extends into the manifold or extends into the gas tank of the vehicle.
