METHOD AND DEVICE FOR ENGINE SPEED CONTROL AND JIB-TYPE ENGINEERING MACHINE Russian patent published in 2016 - IPC F02D29/02 B66C13/18 E04G21/04 

FIELD: engines.

SUBSTANCE: method of engine speed control is designed to control output engine speed of a boom-type engineering machine during a boom action includes: detecting a load pressure of a hydraulic system and a moving speed of a boom; determining a target speed of the engine according to the load pressure and the moving speed of the boom, by a central control unit; sending, by the central control unit, the target speed of the engine to an engine control unit, and performing, by the engine control unit, a speed closed-loop adjustment according to a current speed value fed back by the engine, so that a current speed of the engine is consistent with the target speed of the engine.

EFFECT: additional aspects of the invention are a device for engine speed control and boom-type engineering machine containing device for engine speed control.
