Specific embodiment
As shown in Figures 2 and 3, a kind of system for lifting commercial vehicle engine exhaust performance, including engine 1, dissipates
Hot device 2, secondary water tank 3, monitoring part, control section and regulation part；The air inlet of secondary water tank 3 passes through threeway permeability cell and starts
The ventilation mouth of machine and radiator connects；Threeway permeability cell by ventilative supervisor 301 and is connected to the ventilative arm on ventilative supervisor 301
302 compositions, ventilative supervisor 301 is connected with the ventilation mouth of radiator 2, ventilative on another ventilative arm 302 and engine cylinder lid
Mouth connects；The delivery port of secondary water tank 3 is connected with the water inlet of engine 1 by transparent flexible rubber hose 4；Monitoring part includes air pressure transmission
Sensor 5, flow sensor 6, temperature sensor 7, ultrasonic bubble detection sensor 8；Baroceptor 5 is arranged on threeway permeability cell
Outlet side on, baroceptor 5 is used for monitoring the air pressure that engine and radiator are discharged；Flow sensor 6 is arranged on and starts
Machine water inlet, flow sensor is used for monitoring and enters in-engine coolant rate；Temperature sensor 7 is arranged on engine
Water outlet, temperature sensor is used for monitoring the leaving water temperature of engine；Ultrasonic bubble detection sensor 8 is arranged on transparent flexible glue
Guan Shang, ultrasonic bubble detection sensor is used for Air Bubble Size and quantity in detection pipe；Control section is mainly by single-chip microcomputer, control
Switch and alarm composition, single-chip microcomputer provides electric power by vehicle power；Adjust part by water tank lowering or hoisting gear and pressure exhaust valve 9
Composition, water tank lowering or hoisting gear is arranged on vehicle frame, and secondary water tank is arranged on water tank lowering or hoisting gear, and pressure exhaust valve 9 is arranged on
On bright flexible rubber hose；Monitoring part send monitoring signals to control section, the alarm in control section is reported to the police, after warning by
Control section sends a control signal to regulation part.
As shown in figure 4, the structure of described water tank lowering or hoisting gear is: include the casing 11 that can be fixed on vehicle frame 10, casing
It is provided with the guide rail of setting, the chute in guide rail is dovetail groove, is provided with tooth bar 12, the shape of the connecting portion of tooth bar 12 in chute in 11
Shape is matched with dovetail groove, and tooth bar 12 is connected with slide, and the upper end of tooth bar 12 upwardly extends and the rack bore from casing 11
Inside pass, the elongated end of tooth bar 12 is connected with secondary water tank fixed mount 13, and rotating shaft is fixed in casing by bearing, one end of rotating shaft
It is connected with gear 14, its other end is connected with the output shaft of motor, wheel and rack engages；The rotary motion of gear is turned by tooth bar
Turn to linear motion, tooth bar makees elevating movement along the direction of guide rail；Described pair water tank is bolted on fixed mount.
Described baroceptor is arranged on ventilative arm, and baroceptor is used for monitoring the gas that engine and water tank are discharged
Pressure.The purpose of monitoring is to prevent there is excessive cooling water in radiator and the ventilative pipeline of engine, leads to exhaust not smooth；Gas
Body can not return to expansion tank along pipeline, but stays in pipe, leads to cooling water circulation freely not form high pressure, thus leading to cold
But coolant-temperature gage rises comparatively fast.
Described ultrasonic bubble sensor can monitor the quantity of bubble and size in expansion tank, judges expansion tank structure
Reasonability, and determine whether excessive gas with coolant flow into engine in.Coolant is filled into expansion tank
When, should not produce more bubble.For example: after having filled coolant, ultrasonic bubble Sensor monitoring has in expansion tank
Many bubbles of different sizes enter engine with coolant.Again after systemic circulation, gas is arranged by engine through 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 this system improving degasification performance, the number of bubbles of Sensor monitoring declines, and bubble becomes
Little.
Described baroceptor 5, flow sensor 6, the company of temperature sensor 7, ultrasonic bubble detection sensor 8 and body
The mode that connects is known technology, is not described in detail.
Operation principle: when vehicle is run with full load state, if now vehicle exhaust performance is not good, that is monitored sends out
Pressure in motivation leaving water temperature and ventilative arm will substantially rise, and transmit signals to single-chip microcomputer, exceed setting value and (close on
Temperature and pressure when boiling) after, single-chip microcomputer sends a signal to alarm, sends warning.Now driver presses regulation button,
Motor-driven gear tooth bar, makes secondary water tank fixed support rise；After secondary water 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 secondary water tank the quantity of bubble and big
Little, judge the reasonability of secondary cisten mechanism, and determine whether that excessive gas flows in engine with coolant.To expansion
In water tank during filling coolant, should not produce more bubble.After having filled coolant, ultrasonic bubble Sensor monitoring is to swollen
Many bubbles of different sizes are had to enter engine with coolant in swollen water tank.Again after systemic circulation, engine is through removing
Gas is entered 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.Now pressure exhaust valve is opened, and the gas in water is discharged rapidly.By using
This system improving degasification performance, the number of bubbles of Sensor monitoring declines, and bubble diminishes.Additionally, vehicle exhaust performance boost, row
Pressure drop in air pipe, the water temperature drop in pipeline, make vehicle continue normally travel.When coolant returns to normal value,
Alarm cuts out, and controlling switch controls water tank lowering or hoisting gear to be returned to original state.
