Feedback loop controlled multistage aerosol removal device

An assembly for removing aerosol from crankcase gasses being returned to an air intake manifold comprising:

• a housing having a housing wall defining a top portion and a base with at least one drain,
• an inlet line extending through said housing wall for communicating with a crankcase,
• an outlet line extending through said top portion for communicating with an air intake manifold,
• an inertial separator attached to said inlet line and having a screen through which the gasses pass and having an impacter plate for obstructing aerosol suspended in the gasses,
• a sheet wound in spaced convolutions to define a spiraled path from the exterior to a central space for conveying gasses from said inertial separator to said central space,
• thermal interception tube located in said central space for receiving gasses, said tube having a porous wall for gasses to pass therethrough, an opening at one end for egress of gasses, and
• first and second drains wherein said first drain includes a first valve, and said second drain includes a second valve for draining aerosol and fluids extracted from the gasses.

A method for separating aerosol from crankcase gases comprising the steps of:

• passing the gases through a screen and impacting the gases against an impacter plate for obstructing aerosol suspended in the gases,
• circulating the gases in a spiraled path to a central space to remove aerosol from the gases,
• filtering the gases through a thermal interception tube disposed in the central space,
• returning the gases to an air intake manifold, and cooling the gases at the thermal interception tube in the central space.

An assembly for removing aerosol from crankcase gasses being returned to an air intake manifold comprising:

• a housing having a housing wall, a top and a base defining an inner cavity, at least one drain communicating with said inner cavity,
• at least one drain communicating with said inner cavity,
• an inlet line extending through said housing wall into said cavity, said inlet line being adapted for connection to a crankcase,
• an inertial separator adjacent said inlet line for obstructing aerosol suspended in the gasses, said obstructed aerosol entering said first drain,
• a diffusion battery having a circuitous path for slowing the gasses and sequentially dropping aerosol of reduced size as the gas slows, the gas entering the diffusion battery and flowing along said circuitous path to a central space, and
• a thermal interception tube located in said central space for receiving gases, said thermal interception tube having a porous wall for gases to pass therethrough, an opening communicating with said outlet line for egress of gasses and a chiller for reducing the temperature of said thermal interception tube and causing condensation on said tube wall.
