    摘要: A method and apparatus for the treatment of blow-by gas from a crankcase of an internal combustion engine. A particle and droplet filter removes at least some of any particles or droplets in the gaseous stream. The filtered gaseous stream is passed through a primary heat exchanger, and a catalyzed soot filter downstream of the primary heat exchanger. A secondary heat exchanger may be used to heat the gaseous stream with exhaust gas from the internal combustion engine. Blow-by gases are cleaned for subsequent discharge to the ambient environment, or for reintroduction to the fuel system of the engine.

    摘要: A leakage arresting system comprising a novel gas arrestor for installation on an interrupted pintle shaft in a pintle-type valve, such as an exhaust gas recirculation valve for an internal combustion engine, for preventing leakage of gas and moisture along the pintle shaft into the actuator, to prevent corrosion and failure of the actuator. The system comprises two elements: a pintle shaft which is interrupted outside the actuator, and a positive vapor block in the form of a cup-shaped arrestor disposed across the pintle interruption. The invention is applicable to both unbalanced and force-balanced valves.
