摘要： 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.

摘要： A combustion engine for a vehicle has an intake duct through which a fuel gas/air/exhaust gas mixture can be fed to a combustion unit of the combustion engine, and an exhaust gas recirculation system feeding in an exhaust gas from the combustion unit at an exhaust gas admission region to the gas fed to the combustion unit. A measuring device that determines the fuel gas/air/exhaust gas mass flow and the fuel gas/air/exhaust gas temperature is arranged in the intake duct upstream of the combustion unit and downstream of the exhaust gas admission region. A temperature sensor is arranged both in the exhaust gas recirculation system and in the intake duct, in each case upstream of the exhaust gas admission region, in addition to the measuring device, to determine a recirculated exhaust gas mass flow and/or an air mass flow fed to the combustion unit.
