Abstract

To correct the air-fuel mixture of combustion engines the system has a sensor in the exhaust which analyses the gasses and transmits at frequent internvals impulses which vary in time recording to analysis. These impulses are received by an electro-valve which opens and closes if impulses are outside certain preset limits. This electro-valve modulates the vacuum in the carburettor. This vacuum forms a function for the action of a membrane which can activate an auxiliary air valve injector to restore right amount of air according to analysis of exhaust gasses.
