摘要： A homogenization apparatus for at least two fluid flows for homogeneous gas/air mixing in a gas engine, in which at least two fluid feed lines conducting different fluid flows and one fluid outflow line conducting the homogenized fluid are connected to a central homogenization space as mixing region. In a connection region upstream of the homogenization space, the fluid feed lines have in each case one line section with a flow deflection in one direction with a flow deflection which follows downstream in the other direction and are connected in such a way that the fluid flows are fed tangentially to the homogenization space with a swirl movement imparted to them, in such a way that a rotating, turbulent flow which assists the homogenization process is formed in the homogenization space.

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.
