Pollution control system

A pollution control system, comprising:

• a PCV valve having an inlet and an outlet adapted to vent blow-by gas out from an internal combustion engine, wherein the inlet connects to a crankcase and the outlet connects to an intake manifold of the internal combustion engine;
• a fluid regulator separate from but associated with the PCV valve for selectively modulating engine vacuum pressure to adjustably increase or decrease a fluid flow rate of blow-by gas venting from the internal combustion engine;
• a controller for adjustably positioning the fluid regulator to vary engine vacuum pressure based, in part, on measurements from a sensor;
• and
• an oil trap fluidly coupled to the PCV valve for condensing vaporized oil in the blow-by gas into a liquid for reuse in the internal combustion engine.

A pollution control system, comprising:

• a PCV valve having an inlet and an outlet adapted to vent blow-by gas out from an internal combustion engine, wherein the inlet connects to a crankcase and the outlet connects to an intake manifold of the internal combustion engine;
• a fluid regulator comprising a selectively positionable screw integral to a line block associated with but separate from the PCV valve for selectively modulating engine vacuum pressure to adjustably increase or decrease a fluid flow rate of blow-by gas venting from the internal combustion engine;
• a controller for adjustably positioning the fluid regulator in real-time to vary engine vacuum pressure based, in part, on measurements from a sensor, wherein the controller decreases engine vacuum pressure during periods of decreased blow-by gas production to decrease the fluid flow rate through the PCV valve by inserting the screw into the line block, and increases engine vacuum pressure during periods of increased blow-by gas production to increase the fluid flow rate through the PCV valve by removing the screw out from within the line block;
• a set of oil traps, each comprising a frusto-conical container with an internal oil filter, fluidly coupled to the PCV valve in series or in parallel with one another for condensing vaporized oil in the blow-by gas into a liquid for reuse in the internal combustion engine, wherein the volume of the oil trap is relatively larger than the volume of a vent line carrying the blow-by gas to the oil trap from the internal combustion engine;
• and
• a drain line coupled to the oil trap for returning liquid oil to the internal combustion engine via a dipstick chamber, wherein the vent line and the drain line couple to different portions of the oil trap such that the vacuum drawing the blow-by gas through the oil trap does not interfere with the drainage of the liquid oil back to the internal combustion engine.
