Abstract
The present invention discloses a method for identifying the concentration of fuels or gases in air, particularly in the intake of motor vehicle motors, with ultrasound measurement, comprising the steps of conducting an air/vapor mixture whose concentration is to be identified through an ultrasound measuring section of known length, directing ultrasound through the mixture in the measuring section, determining the speed of sound through the air/vapor mixture; and identifying the concentration of the mixture on the basis of the speed of sound through the mixture in the measuring section.
