FIELD: machine building.
SUBSTANCE: invention refers to procedure and device of control for opening valve mechanism of containing cooling fluid circuit for internal combustion engine cooling. The device is opened under effect of cooling fluid heated to standard temperature. According to the invention there is performed an advance controlled opening of the valve mechanism installed in the cooling circuit at input to a heat exchanger prior to moment, when temperature of cooling fluid reaches temperature of actuation for valve mechanism opening. Also, temperature of actuation proper is below standard temperature, while controlled opening occurs only at the first opening of the valve mechanism.
EFFECT: reduced consumption of fuel, and reduced amount of toxic pollutants.
