Pressure-charged diesel engines often generate �blow-by� gases, i.e., a flow of air-fuel mixture leaking past pistons from the combustion chambers. Such �blow-by gases� generally comprise a gas phase, for example air or combustion off gases, carrying therein: (a) hydrophobic fluid (e.g., oil including fuel aerosol) principally comprising 0.1-5.0 micron droplets (principally, by number); and, (b) carbon contaminant from combustion, typically comprising carbon particles, a majority of which are about 0.1-10 microns in size. Such �blow-by gases� are generally directed outwardly from the engine block, through a blow-by vent.
Cartridge 2000 could be configured for either in-to-out flow or out-to-in flow. When configured for in-to-out flow, as will be typical for an arrangement as described in the other figures, the upstream edge of the media 2001 would be at 2001 a and the downstream edge at 2001 b.
