Power supply is 24V or 12V automobile storage battery direct current, through being the 5V direct current behind two three terminal regulator Q1, the Q2.When engine temperature changes, water temperature sensing BT1, the resistance value of BT2 device also changes thereupon, this variation becomes electrical signal through triode T1 through sample circuit, after T2 amplifies, again through adjusting circuit input scmitt trigger circuit IC1, when electrical signal is enough big, scmitt trigger circuit IC1 upset, the output high level makes triode T4 saturation conduction, the relay J conducting, solenoid valve D opens, engine cooling system enters the major cycle state, and engine temperature is descended, and sets 80-90 ℃ when requiring when engine temperature reaches, scmitt trigger circuit IC1 overturns once more, output low level, triode T1 becomes cut-off state by conducting, and relay J disconnects, controlled solenoid valve D closes, and engine cooling system enters the short circle state.And so forth, the temperature of engine cooling water is remained between 80-90 ℃, to satisfy the needs of heating automobile system.Buzzer F sounds when engine cooling water temperature surpasses 95 ℃ of setting values, and prompting driver engine water temperature is too high, and this moment, the driver only needed manual ball valve handle 19 is opened, and engine cooling system is forced to be in the major cycle state, makes the motor cooling.
In case second, in order to prevent that solenoid valve or control circuit from breaking down, when water temperature reached 90 ℃ in the engine body, solenoid valve control circuit can not be opened, cause engine temperature too high and motor is caused damage easily.Installed a high temperature alarm system on this basis additional, when engine water temperature was higher than 95 ℃, this system was by independently being arranged on the cooling-water temperature sensor BT2 on the engine body, and signal amplifier, buzzer F sound, and report to the police to the driver.
Three, in order to prevent because solenoid valve and control circuit produce fault or summer because the too small too high vehicle lay-off that causes of engine water temperature that causes of water route sectional area that electromagnetic valve can be passed through, so manual ball valve in parallel with solenoid valve, in case the phenomenon that appearance is reported to the police because of engine water temperature is too high, getting rid of engine cooling is under the prerequisite of other faults, the driver only needs manual ball valve handle 19 is opened, engine cooling system will be in the major cycle state, the automatically controlled failure of apparatus of water route break-make this moment.
In line with practical, simple, with low cost, reliable operation, principle easy and simple to handle, the mode that the present invention has adopted solenoid valve to combine with manual ball valve parallel connection.With solenoid valve and manual ball valve design is one, the shared entery and delivery port of two valves, and designed the signal amplifier that is complementary with cooling-water temperature sensor BT1, BT2 that is installed on the engine body, by cooling-water temperature sensor BT1, BT2, signal amplifier, relay J are controlled the purpose of engine temperature being carried out constant control to realize to the break-make of the electromagnetic coil of solenoid valve.Main contents of the present invention are: 1, solenoid valve and the manual ball valve mode by casting is integrated, the purpose (as shown in Figure 1) being convenient to install little with implementation structure compactness, volume.2, the signal of engine water temperature sensor BT1, BT2 is transmitted and amplify, by signal amplifier low temperature outage, high temperature energising, three signaling points of superhigh temperature warning are amplified processing, thereby the break-make and the superhigh temperature buzzer F of solenoid valve controlled (as shown in Figure 2).
Working procedure of the present invention is: voltage stabilizer Q1, Q2 provide operating voltage for circuit.When temperature variation, the also variation thereupon of resistance value of the cooling-water temperature sensor BT2 that start to control the cooling-water temperature sensor BT1 that makes usefulness, plays the warning effect, this variation becomes electrical signal through sample circuit.The electrical signal of BT1 is adjusted input scmitt trigger circuit IC1 through potentiometer W3, W4 again after triode T1, T2 amplify.When electrical signal is enough big, scmitt trigger circuit IC1 upset, the output high level, make triode T4 saturation conduction, the relay J action, controlled water valve is opened, and engine cooling system enters the major cycle state, be cooling system circulating water through engine water pump-engine body water jacket-heat radiation sebific duct-upper header--radiator lower header-sebific duct-engine water pump is promptly finished a work cycle, make engine temperature decline.When engine temperature is lower than setting value 80-90 ℃, scmitt trigger circuit IC1 overturns once more, output low level, triode T4 becomes cut-off state by conducting, relay J disconnects, controlled solenoid valve D closes, and engine cooling system enters the short circle state, and promptly the circulating water of cooling system is through engine water pump--engine body water jacket-water pump is promptly finished a work cycle.This short circle water is because without radiator, therefore heating up to reach setting value 80-90 ℃ rapidly fast.When engine cooling water temperature surpasses 95 ℃ of limit values, the electrical signal of cooling-water temperature sensor BT2 causes scmitt trigger circuit IC1 control triode T3 conducting, buzzer F sounds, prompting driver engine water temperature is too high, this moment, the driver only needed manual water valve handle 19 is opened, engine cooling system promptly is forced to be in the major cycle state, makes the motor cooling.And so forth, the temperature of engine cooling water is remained between 80-90 ℃, to satisfy the needs of heating automobile system.
The present invention is through experiment on the C-26146 AsiaSat JS6101G1C84H motor bus of Shandong (annotate: this car is a comings JQB210-10 diesel engine) road examination, for carrying out the data contrast experiment with tail gas heating heating plant under+15 ℃ the condition, laboratory data sees the following form in ambient temperature.
The product laboratory data table of comparisons
Annotate: ambient temperature+15 ℃
By the above data table of comparisons as can be seen, engine temperature controller and automatical control system are installed on same chassis, no matter on engine warms speed, oil consumption, heating effect still are engine temperature stability, all are better than tail gas heating heating plant.Advance of the present invention and practicability have been shown thus.
Metallic material casting processing such as mechanical part of the present invention can copper, aluminium, gray iron, carbon steel form, but consider the attractive in appearance and quality of manufacture cost and product, and the most handy carbon steel carries out precision casting, processing.Consider that the formed product of the present invention needs long period of soaking to carry out work in the liquid of water or weak acid and weak base, carry out the surface plating after valve ball, valve ball Control Shaft, the axis of guide, electromagnetic induction axle, guider, spring, the most handy stainless steel manufacturing of screw or the Ordinary Steel processing as shown in Figure 1 and iron processing.
