| description | The present invention relates generally to internal combustion engines, and, more particularly, to a method and apparatus for treating blow-by gases found in the crankcase of an internal combustion engine.
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. |
