ENGINE CONTROL METHOD AND CONTROL DEVICE Russian patent published in 2019 - IPC F02D45/00 

FIELD: engine building.

SUBSTANCE: invention relates to a method and an apparatus for controlling an engine. Result is achieved by that engine control device sets target torque of engine and controls engine torque based on set target torque. Permissible torque exceeding target torque is set, and multiple different operating conditions are detected as indicators indicating actual engine operating state. Actual torques which are actual engine torques are individually calculated based on the plurality of detected operating state parameters, and the highest value among the calculated actual torques is selected as the final actual torque. Selected actual torque is compared with the allowable torque to form a control signal according to the result of comparison between the actual torque and the allowable torque.

EFFECT: improving engine reliability and maintaining its operational characteristics.
