1 appropriate working temperature of machine；
When the coolant temperature in 12 water jacket of cylinder body is raised to 82 DEG C, the thermostat 4 in the outlet of 12 water jacket of cylinder body is closed entirely
It opens, the coolant liquid in 12 water jacket of cylinder body is mixed together with the coolant liquid in Cooling of Cylinder Head circuit by entering in Cooling of Cylinder Head circuit
After conjunction, flowed back in 12 water jacket of cylinder body after being recycled in Cooling of Cylinder Head circuit, to be followed in 12 water jacket of 11 water jacket of cylinder cap and cylinder body
Ring.Coolant liquid in 12 water jacket of cylinder body makes in 12 water jacket of cylinder body because mixing and recycling with the coolant liquid in Cooling of Cylinder Head circuit
Coolant liquid heating rate slows down, and engine 1 is maintained to work under preference temperature；
When the coolant temperature in 11 water jacket of 12 water jacket of cylinder body and cylinder cap is raised to 95 DEG C, radiator 3 and Cooling of Cylinder Head are returned
4 standard-sized sheet of thermostat between road, water pump 2 drive the coolant liquid in 12 water jacket of cylinder body and 11 water jacket of cylinder cap to flow through the progress of radiator 3
It after cooling, then flows back in 11 water jacket of 12 water jacket of cylinder body and cylinder cap, cools down to the engine 1 continued working, maintain engine 1
It works within the scope of one suitable temperature.
Further, engine-cooling system further includes expansion tank, expansion tank and Cooling of Cylinder Head circuit communication.
When coolant liquid constantly recycles in Cooling of Cylinder Head circuit, expansion tank can be flowed through halfway, if coolant pressure
Excessively high or coolant liquid is excessive, and extra gas or coolant liquid will be flowed out from the bypass water channel of expansion tank, avoids engine cool
System pressure is excessively high, causes the ill effect of booster.
