Abstract
Fuel proportioning in a gas-powered combustion engine is effected so that when the value of a parameter monitored in the exhaust gases deviates from a set-value, the level of the gas input pressure to a mixer for gas and air is adjusted in a specified operating situation so that said set-value is established. A device for fuel proportioning includes a pressure regulator (3) whereby the outlet pressure can be adjusted automatically during a specified operating situation by means of a control unit (11). After adjustment has been carried out, the setting reached is maintained for a lengthy period.
