Abstract

The pollution control system includes a controller coupled to a sensor monitoring an operational characteristic of a combustion engine, such as engine RPM. A PCV valve having an inlet and an outlet is adapted to vent blow-by gas out from the combustion engine. A fluid regulator associated with the PCV valve and responsive to the controller selectively modulates engine vacuum pressure to adjustably increase or decrease a fluid flow rate of blow-by gas venting from the combustion engine. The controller selectively adjustably positions the fluid regulator to vary the degree of vacuum pressure to optimize the recycling of blow-by gases.

Claims

1. A pollution control system, comprising:

a controller coupled to a sensor monitoring an operational characteristic of a combustion engine;

a PCV valve having an inlet and an outlet adapted to vent blow-by gas out from the combustion engine; and

a fluid regulator associated with the PCV valve and responsive to the controller for selectively modulating engine vacuum pressure to adjustably increase or decrease a fluid flow rate of blow-by gas venting from the combustion engine.

2. The system of claim 1, wherein the controller decreases the engine vacuum pressure during periods of decreased blow-by gas production to decrease the fluid flow rate through the PCV valve, and increases the engine vacuum pressure during periods of increased blow-by gas production to increase the fluid flow rate through the PCV valve.

3. The system of claim 1, including a supplemental fuel fluidly coupled to the PCV valve and the fluid regulator.

4. The system of claim 3, including a one-way check valve electronically coupled to the controller for selectively modulating release of the supplemental fuel to the PCV valve and the fluid regulator.

5. The system of claim 4, wherein the supplemental fuel comprises a compressed natural gas (CNG) or a hydrogen gas.

6. The system of claim 5, including a hydrogen generator associated with the controller and responsive thereto for making the hydrogen gas on demand.

7. The system of claim 1, wherein the controller includes a pre-programmed software program, a flash-updatable software program, or a behavior-learning software program.

8. The system of claim 1, wherein the controller adjustably positions the fluid regulator to vary the engine vacuum pressure based, in part, on measurements from the sensor.

9. The system of claim 1, wherein the controller includes a window switch coupled to an engine RPM sensor, wherein the fluid regulator is selectively positionable based on a predetermined engine RPM or multiple engine RPMs set by the window switch.

10. The system of claim 1, wherein the controller activates and/or deactivates the fluid regulator at an engine frequency or a set of engine frequencies.

11. The system of claim 1, wherein the controller includes an on-delay timer that sets the fluid regulator to preclude fluid flow for a predetermined duration after activation of the combustion engine.

12. The system of claim 11, wherein the predetermined duration is a function of time, engine temperature, or engine RPM.

13. The system of claim 1, wherein the PCV valve comprises a two-stage check valve.

14. The system of claim 1, wherein the controller includes a wireless transmitter or a wireless receiver.

15. The system of claim 1, wherein the sensor comprises an engine temperature sensor, a spark plug sensor, an accelerometer sensor, a PCV valve sensor, or an exhaust sensor.

16. The system of claim 15, wherein the operational characteristic comprises an engine temperature, a quantity of engine cylinders, a real-time acceleration calculation, or an engine RPM.

17. The system of claim 1, wherein the inlet connects to a crankcase and the outlet connects to an intake manifold of an internal combustion engine.

18. The system of claim 1, wherein the fluid regulator comprises a flow control orifice.

19. The system of claim 18, wherein the pollution control system defaults back to an OEM setting with the flow control orifice if the controller and the PCV valve fails.
