摘要： A method is provided for controlling the engine torque delivered during engine operation. The method includes, but is not limited to setting a brake torque request value during the engine operation, deriving a request fuel quantity value on the basis of the brake torque request value. The comparison of the value of the brake torque requested with a measured and/or estimated brake torque value allows calculating a brake torque error value, which directly or indirectly modifies the request fuel quantity injected in the engine.

摘要： A method for operating an internal combustion engine includes injecting a quantity of fuel in the engine per engine cycle. A total value of the fuel quantity is evaluated as the sum of a fuel quantity base value and a fuel quantity correction value. The fuel quantity base value is determined based on a requested value of engine torque to be generated in the engine cycle. The fuel quantity correction value is determined based on an engine torque error in a previous engine cycle, which is calculated as a difference between a value of engine torque generated in the previous engine cycle and the requested value of engine torque for the previous engine cycle.
