摘要： In an internal combustion engine, a real fuel quantity (rk_w), supplied from a high-pressure region of a fuel system into a combustion chamber of the engine, depends on a real rotational moment. In addition, the control duration (dwmsvo) of a volume control valve, with which the fuel supplied from a fuel pump into the high-pressure region can be affected, depends on the difference between a real pressure and a determined pressure (prist) in the high-pressure region. The supply output of the fuel pump, which supplies into the high-pressure region, depends in turn on the rotational speed (nmot) of a crankshaft of the engine. In order to avoid problems relating to too much or too little fuel being injected into the combustion chamber of the engine, it is proposed that a real control duration (dwmsvo) of the volume control valve, the determined rotational speed (nmot) of the crankshaft of the engine, and the determined pressure (prist) in the high-pressure region determine a test fuel quantity (rk_um) and that this test fuel quantity is compared with a real fuel quantity (rk_w_determined from the real rotational moment.
