ABSTRACT:
Noxious emissions present in the exhaust gases of an internal-combustion engine of a motor vehicle are controlled by making use of an IR spectrophotometer provided on board the motor vehicle, for the purpose of obtaining an analysis of all the main components of the exhaust gases of the engine. The IR spectrophotometer is of the type with electrostatic micro-shutters so as to present overall dimensions designed to enable its use on board the motor vehicle.
