Summary:mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to devices for automatically changing the engine for idling. Proposed device has current sensor whose input is coupled with loads and output is coupled through threshold element and amplifier with engine throttle valve. Device includes additionally temperature transmitter whose input is coupled with actuator, and second threshold element. Current sensor contains discrete element. All threshold elements are made in form of logic NAND gates whose outputs are connected in parallel to each other. Input of first logic NAND gate is coupled with current sensor, input of second logic NAND gate is coupled with temperature transmitter. EFFECT: improved reliability, reduced consumption of electric energy, enlarged operating capabilities owing to possibility of operation by two channels. 1 dwg
