Being delivered to adhesive disk, thus driving the support plate within adhesive disk, axle sleeve and belt pulley synchronous axial system, realizing water pump vane operating
Work is it is ensured that the normal cooling demand of electromotor.
Cooling circulation, the cooling of thermostat application cylider cover water jacket are controlled using the thermostat opened at the beginning of two different temperatures
Liquid, thermostat controls the coolant of cylinder body water jacket.According to the different cooling requirement of gray iron, it is independently controlled.By
When electromotor is in low temperature, toggle friction loss is larger, using thermostat, cylinder body is individually controlled, can be rapid
Heating cylinder body, reduces friction loss, and then improves the economy of electromotor.Simultaneously as supercharged direct-injection engine is burned
Substantial amounts of heat is produced, coolant needs to take away more heats to ensure the normal work of cylinder cap, using cylinder body pair water in journey
Nested structure, by 2/3rds drains of coolant total amount to cylinder cap, for cooling down combustor.Meanwhile, cylinder cover water jacket structure design
Allow more coolants flow to exhaust side it is ensured that cylinder cap inlet and outlet side uniformly cools down, reduce the temperature of combustor, increased
Volumetric efficiency, and reduce the probability of pinking generation.
According to the different operating modes of engine demand, the different temperatures of coolant, by the control to water pump, in cold start-up
Make rapidly electromotor reach optimum working temperature, reduce the friction loss of mechanical part, save the power loss of water pump operation.
