COOLING SYSTEM OF AUTO-TRACTOR ENGINE Russian patent published in 2021 - IPC F01P3/20 F01P11/06 

FIELD: cooling systems.

SUBSTANCE: invention can be used in engine cooling systems of auto-tractor equipment. A cooling system of an auto-tractor engine cooling system contains cooling jackets for cylinder head and block (1), water pump (2), thermostat (3), radiator (4), cabin heater (5), expansion tank (6), electric fan (7), heater pump (8), taps (9), drain plugs (10), coolant temperature sensor (11) with engine regulation controller (12), lines (13), (14) for the removal and intake of coolant. When the valve of thermostat (3) is in the closed state, coolant from water pump (2) is directed to the cooling jacket for cylinder head and block (1). Part of coolant is diverted to line (14) for intake cabin heater (5) by heater pump (8). When valve of thermostat (3) located on cylinder head (1) is opened, part of heated coolant goes into radiator (4). Filters (15) are installed in line (13) for the removal of coolant to expansion tank (6) and in line (14) for the intake of coolant.

EFFECT: increase in the reliability and durability of the auto-tractor engine.
