Specific implementation mode
As shown in Figures 2 and 3, a kind of system for promoting commercial vehicle engine exhaust performance, including engine 1, dissipate
Hot device 2, deputy tank 3, monitoring part, control section and adjusting part；The air inlet of deputy tank 3 by threeway permeability cell with start
The ventilation mouth of machine and radiator connects；Threeway permeability cell is by ventilative supervisor 301 and the ventilative branch pipe being connected on ventilative supervisor 301
302 are constituted, and ventilative supervisor 301 connect with the ventilation mouth of radiator 2, and another ventilative branch pipe 302 covers ventilative with engine cylinder
Mouth connection；The water outlet of deputy tank 3 is connect by transparent flexible rubber hose 4 with the water inlet of engine 1；Monitoring portion point includes air pressure transmission
Sensor 5, flow sensor 6, temperature sensor 7, ultrasonic bubble detection sensor 8；Baroceptor 5 is mounted on threeway permeability cell
Outlet side on, baroceptor 5 be used for monitor engine and radiator discharge air pressure；Flow sensor 6, which is mounted on, to be started
Machine water inlet, flow sensor enter in-engine coolant rate for monitoring；Temperature sensor 7 is mounted on engine
Water outlet, temperature sensor are used to monitor the leaving water temperature of engine；Ultrasonic bubble detection sensor 8 is mounted on transparent flexible glue
Guan Shang, ultrasonic bubble detection sensor are used for the Air Bubble Size in detection pipe and quantity；Control section is mainly by microcontroller, control
Switch and alarm composition, microcontroller provide electric power by vehicle power supply；Part is adjusted by water tank lifting gear and pressure exhaust valve 9
Composition, water tank lifting gear are mounted on vehicle frame, and deputy tank is mounted on water tank lifting gear, and pressure exhaust valve 9 is mounted on saturating
On bright flexible rubber hose；Monitoring portion distribution send monitoring signals to control section, and the alarm in control section is alarmed, after alarm by
Control section, which is sent a control signal to, adjusts part.
As shown in figure 4, the structure of the water tank lifting gear is：Including the babinet 11 that can be fixed on vehicle frame 10, babinet
The guide rail erect is equipped in 11, the sliding slot in guide rail is dovetail groove, and rack 12, the shape of the connecting portion of rack 12 are equipped in sliding slot
Shape matches with dovetail groove, and rack 12 is slidably connected with sliding slot, and the upper end of rack 12 upwardly extends and from the rack bore of babinet 11
It is inside pierced by, the elongated end of rack 12 is connect with deputy tank fixed frame 13, and shaft is fixed on by bearing in babinet, one end of shaft
It is connect with gear 14, the output axis connection of its other end and motor, wheel and rack engagement；Rack turns the rotary motion of gear
Linear motion is turned to, rack makees elevating movement along the direction of guide rail；The deputy tank is bolted on fixed frame.
The baroceptor is mounted on ventilative branch pipe, and baroceptor is used to monitor engine and the gas of water tank discharge
Pressure.The purpose of monitoring is that have excessive cooling water in the ventilative pipeline for prevent radiator and engine, causes to be vented unsmooth；Gas
Body cannot return to expansion tank along pipeline, but stay in pipe, lead to the unsmooth formation high pressure of cooling water circulation, so as to cause cold
But coolant-temperature gage rises very fast.
The ultrasonic bubble sensor can monitor the quantity and size of bubble in expansion tank, judge expansion tank structure
Reasonability, and judge whether there is excessive gas with coolant liquid flow into engine in.Coolant liquid is filled into expansion tank
When, more bubble should not be generated.Such as：After having filled coolant liquid, have in ultrasonic bubble Sensor monitoring to expansion tank
Many bubbles of different sizes enter engine with coolant liquid.After systemic circulation, engine arranges gas by degasification
Enter the cooling ullage of expansion tank.If engine degasification poor performance, the bubble that ultrasonic bubble sensor is monitored
Quantity is still more, still larger.By using the system improving degasification performance, the number of bubbles of Sensor monitoring declines, and bubble becomes
It is small.
The company of the baroceptor 5, flow sensor 6, temperature sensor 7, ultrasonic bubble detection sensor 8 and tube body
It is well known technology to connect mode, is not described in detail.
Operation principle：When vehicle is run with full load state, if vehicle exhaust performance is bad at this time, the hair monitored
Pressure in motivation leaving water temperature and ventilative branch pipe will obviously rise, and transmit signals to microcontroller, be more than setting value（It closes on
Temperature and pressure when boiling）Afterwards, microcontroller sends a signal to alarm, sends out alarm.Driver presses regulation button at this time,
Motor-driven gear rack makes deputy tank fixing bracket rise；After deputy tank rises, the hydraulic pressure in transparent flexible rubber hose increases,
Gas in water can isolate the water surface in the form of bubbles.Ultrasonic bubble sensor can monitor in deputy tank the quantity of bubble and big
It is small, judge the reasonability of deputy tank structure, and judge whether there is excessive gas and flowed into engine with coolant liquid.To expansion
In water tank when filling coolant liquid, more bubble should not be generated.After having filled coolant liquid, ultrasonic bubble Sensor monitoring is to swollen
There are many bubble of different sizes as coolant liquid enters engine in swollen water tank.After systemic circulation, engine is by removing
Gas is discharged into the cooling ullage of expansion tank by gas.If engine degasification poor performance, ultrasonic bubble sensor institute
The number of bubbles of monitoring is still more, still larger.Pressure exhaust valve is opened at this time, and the gas in water is discharged rapidly.By using
The number of bubbles of the system improving degasification performance, Sensor monitoring declines, and bubble becomes smaller.In addition, vehicle exhaust performance boost, row
Pressure in air pipe declines, and the water temperature drop in pipeline makes vehicle continue normally travel.When coolant liquid is restored to normal value,
Alarm is closed, and control switch control water tank lifting gear is returned to original state.
