Microcontroller for pollution control system for an internal combustion engine

Abstract

A pollution control system for an internal combustion engine includes a microcontroller and a power supply, a plurality of sensors configured to measure operating parameters of the engine, and a PCV valve responsive to a control signal from the microcontroller and configured to regulate a flow rate of blow-by gasses in the engine. The microcontroller includes programmable flash memory connected to a control processor, a power supply input, a sensor input configured to receive data from an engine sensor, and a signal output configured to transmit a signal from the control processor so as to control operation of a PCV valve regulating a flow rate of blow-by gasses in the engine.
