During engine cold starting, the time length of warming-up is most important to fuel oil efficiency of combustion and the discharge performance of electromotor.At present, Electromotor generally uses thermostat, electronic thermostat and electronic water pump etc. to control the process of warming-up.
Thermostat, i.e. tradition thermostat, during engine warm-up, control the opening and closing in coolant systemic circulation water route, Thus realize the warming-up of electromotor.The warming-up process of electromotor mainly includes three phases, and first stage is coolant partial circulating, When the temperature (water temperature) below about 76 DEG C of coolant, controlling the valve closing of systemic circulation, coolant is not passed through radiator, only Between engine water jacket and water pump, carry out the flowing of partial circulating, say, that coolant flow through cooling jacket-thermoregulator-water pump- Cooling jacket, so that the temperature of engine coolant rises rapidly, thus ensures that electromotor reaches normal operating temperature. Second stage is coolant mixing circulation, when the temperature of coolant is more than 76 DEG C, and the valve opening of control systemic circulation, and with The aperture of the temperature increasing control valve door of coolant is gradually increased.Now, partial circulating and the systemic circulation of coolant is opened simultaneously and is carried out The mixing circulation of coolant, but the time of mixing circulation is not the longest.Three phases is coolant systemic circulation, works as coolant Temperature when being increased to about 88 DEG C, the valve controlling systemic circulation fully opens, and coolant all flows through radiator from water pump, also That is, coolant flows through cooling jacket-thermoregulator-water pump-bypass oil radiator-radiator-thermoregulator-cooling jacket.Now, Flow of cooling water route is long, and flow is big, and intensity of cooling is big, to promote the temperature rapid decrease of coolant, so that coolant Temperature be unlikely to too high.
Electronic thermostat, on the basis of mechanical type thermostat, adds a resistance wire to realize electrically heated function, coordinates cold But the action of systemic circulation valve is adjusted by liquid temp so that it is response ratio is very fast, just opens such that it is able to improve systemic circulation valve Temperature when opening, it is achieved rapid warming-up.
Electronic water pump is then transmitted by the power of its internal electron clutch for clutch control water pump, controls the static of coolant and circulation, thus Shorten warm-up period.
But the problem that presently, there are is, use thermostat exist when the valve of systemic circulation is crack coolant temperature relatively low and rise The shortcomings such as temperature low-response.Electronic thermostat is used to improve limited to the process of warming-up, cold on the one hand can not regulating partial circulating pipeline But the flow velocity of liquid, on the other hand each pipeline whole after the valve of systemic circulation is crack, in whole engine-cooling system Rise and participate in circulation, cause the time of warming-up to lengthen.Additionally, control more complicated when using electronic water pump during warming-up, Cause demarcating complicated and relatively costly.
