<p>A pollution control system for diesel engines includes a PCV valve and an oil filter positioned together in a canister. The PCV valve has an inlet and an outlet adapted to vent blow-by gas from a diesel combustion engine. A fluid regulator associated with the PCV valve selectively modulates engine vacuum pressure to adjustably increase or decrease a fluid flow rate of blow-by gas venting from the diesel combustion engine. The oil filter cleans particulate matter out of the blow-by gas, and condenses oil to return to the engine. A controller regulates the amount of blow-by gas vented through the system.</p> |
