Abstract

A fuel pump (14) pumps fuel in a method for operating an internal combustion engine (10). The fuel pump (14) is connected at its input end to a fuel tank (12). Fuel reaches at least one combustion chamber (22) of the engine (10) via at least one fuel-injection device (16). In order to be able to inject fuel with still greater accuracy into the combustion chamber (22) of the engine (10), the fuel quantity which arrives in the combustion chamber (22) is determined from the signal of a through-flow measuring device (18).
