ABSTRACT:
A self-cleaning smoke-monitoring system that is used in measuring opacity of exhaust from an internal combustion engine. The invention includes a pair of air passages that supply a flow of filtered air over the optic elements of the smoke-monitoring system. The flow of particulate-free air is the result of a venturi effect created in the exhaust flow such that ambient air is continuously drawn in through the air ducts.
