FIELD: engines.
SUBSTANCE: invention can be used for control of road construction machines internal combustion engines rotation speed. Method of internal combustion engine (1) rotation speed control is intended for road construction machine, which along with motion drive (2) has connected to internal combustion engine (1) hydraulic motors (3) for actuation of working elements and at which rotation speed is adjusted depending on working elements instant power consumption. Hydraulic motors (3) are operated using uncontrolled pumps (5), and reducing currently output residual volume flow rates of active working elements hydraulic motors (3) flow valves (6). Internal combustion engine (1) speed is automatically adapted during operating mode. Disclosed is road construction machine, having internal combustion engine.
EFFECT: technical result consists in reduction of engine excessive energy output.
