  • Adsorption filter for the fuel tank venting system of an internal combustion engine and process for operating said system
    Patent number: 5983870
    Abstract: A process and device are provided to supply the air mass flux required to regenerate the adsorption material of an adsorption filter in the fuel tank venting system of an internal combustion engine while the engine is running and independently of a depression in the air intake pipe of the engine. For this purpose, atmospheric air is fed at least partially and temporarily by an air pump through the adsorption filter to the air intake pipe of the internal combustion engine while the engine is running. The air pump integrated in the device makes it possible to obtain a module which is easy to produce and to handle and which contains all units of the venting system.

  • Cyclone separator for an internal combustion engine
    Patent number: 5460147
    Abstract: A cylindrical cyclone separator connected between an air vent, a suction conduit and an oil sump all of an internal combustion engine. A duct extends spirally within the cyclone separator. Oil and aerosols are separated by an increasing centrifugal force as the oil/aerosol mixtures passes through the duct toward the center of the separator and the separator exhaust ports.
