SYSTEM OF LIQUID COOLING AND QUICK HEATING OF INTERNAL COMBUSTION ENGINE AND DEVICE TO CONTROL LIQUID FLOWS FOR REGULATION OF ENGINE TEMPERATURE

摘要

FIELD: mechanical engineering; cooling and heating systems of internal; combustion engines. SUBSTANCE: proposed system has engine cooling jacket, hot cold circulation circuits, radiator, channel to direct gas from exhaust manifold of engine to heating device, heater of automobile interior with heater radiator, air gate and fan installed inside. System has also electronic temperature control unit with sensor. Heating device is made in form of heat exchanger arranged in radiator drain tank. Liquid flow control device is installed in radiator filler tank. Air gate is arranged behind heater radiator and is made in form of hinge-mounted swivel screen with return spring and servodrive coupled with electronic temperature control unit. EFFECT: reduced time taken for heating engine to working temperature, maintaining working temperature irrespective of ambient air temperature, possibility of choosing temperature depending on load. 5 cl, 12 dwg
