Microcontroller for pollution control system for an internal combustion engine

1. A pollution control system for an internal combustion engine, comprising:

a microcontroller electrically connected to a power supply;

a plurality of sensors connected to the microcontroller, each of the plurality of sensors configured to measure operating parameters of the engine including engine temperature and engine RPMs; and

a PCV valve electrically connected to the microcontroller and responsive to a control signal therefrom, for regulating a flow rate of blow-by gases in the engine; and

wherein the microcontroller has three operating states, comprising:

a first operating state corresponding to an engine condition between ignition and the engine temperature reaching a preferred idle/operation temperature, wherein the microcontroller closes the valve;

a second operating state corresponding to an engine condition after the engine temperature reaches the preferred idle/operation temperature wherein the microcontroller opens the PCV valve when the engine RPMs are within a predefined low/hi window of RPMs; and

a third operating stare corresponding to an engine condition after the engine temperature reaches the preferred idle/operation temperature and the RPMs have been in the predefined low/hi window of RPMs for a predetermined duration wherein the microcontroller periodically opens and closes the PCV valve as long as the RPMs are in the redefined low-hi window.
