Abstract

An internal combustion engine, in particular a gas engine, for a motor vehicle, includes a charge air cooler arranged in an air mass flow feed upstream of an apparatus for mixing in fuel, and a measuring device for determining the air mass flow. The measuring device has a sensor system for measuring a pressure loss across the charge air cooler and a processing unit as evaluation unit for calculating the air mass flow at least from the pressure loss which is measured by the sensor system and a charge air cooler model stored in the processing unit. The charge air cooler forms a geometrically constant throttle for the air mass flow which is flowing through.
