摘要： A method for operating an internal combustion engine (10) having a plurality of cylinders (11), specifically a method for the cylinder-specific detection of misfires, wherein at least one exhaust gas actual value is individually detected by measuring technology using at least one exhaust gas sensor (17) in the exhaust gas of each cylinder (11) of the internal combustion engine (10) for the respective cylinder (11), and the respective exhaust gas actual value which is detected by means of measuring technology is compared with an exhaust gas setpoint value in order to determine, for each of the cylinders (11), at least one cylinder-specific deviation between the exhaust gas setpoint value and the exhaust gas actual value, and wherein, on the basis of the or of each cylinder-specific deviation, it is determined individually for each cylinder (11) whether misfires occur at the respective cylinder (11).
