This increase of consumption during acceleration is THE CARBURETTOR, one of the reasons why, when driven in traffic, a car is more ex- travagant than when driven in the country. Incidentally quite a big saving in fuel can be effected by switching the engine off whenever the car is involved in a long traffic wait.
