Specific embodiment
Below in conjunction with attached drawing, the present invention is described in detail.
Embodiment 1: a kind of auto idle speed abnormal dither adjustment device based on semiconductor chilling plate, structure such as Fig. 1-
Shown in 3, including shell 1,1 is disposed with radiator fan 2, heat-conducting block 3, semiconductor chilling plate 5 under upper and leads in shell
Cold piece 4；
The radiator fan 2, heat-conducting block 3, semiconductor chilling plate 5 and cool guiding block 4 are fastened and connected by bolt；
4 bottom of cool guiding block is equipped with the blind hole 8 for accommodating automotive temp probe.
Lug boss 6 is gone back on the shell 1, the centre of lug boss 6 has binding hole 7.
As a kind of mode for adjusting 5 power of semiconductor chilling plate, the semiconductor chilling plate 5 can be with speed-regulating switch phase
Connection.As the mode of another adjustment 5 power of semiconductor chilling plate, the semiconductor chilling plate 5 can with speed regulation chip and
Power switch is connected.
No matter speed-regulating switch, speed regulation chip and power switch should all be installed in driver's cabin using which kind of mode.
The radiator fan 2 is interference fit with shell 1.When maintenance, radiator fan is firmly pressed, then shell can fall off
Again by Bolt dismantling.
When the present apparatus is installed, runs through binding hole 7 using Plastic Bandage, then the present apparatus is tied up in enging cabin, then will
Temp probe in enging cabin is inserted into blind hole 8.
Essence of the invention is that:
The basic reason of auto idle speed abnormal dither is that frequency of the engine under room temperature idling mode and vehicle frame are solid
There is frequency close, caused by causing vehicle to resonate.External OBD is detected under resonance state, because vehicle motor operates
Well, burning sufficiently, is in normal condition, so any error code will not be shown, therefore the shop 4S and vehicle manufacture manufacturer are not
Engine and vehicle frame can be repaired.Again because engine idling is good, 97, No. 98 gasoline are replaced, are added using gasoline
Add agent, replacing fully synthetic machine oil, heavy-bodied oil and replacement engine support can not inherently solve the problems, such as.Essential problem is also
It is to be how to improve vehicle idling.
In the present apparatus, use process is as follows:
Vehicle igniting, engine idling is about 1300 turns, slow to travel, and vehicle water temperature rises, and oil temperature rises, idling
Decline.Idling steady (i.e. idling is normally rear) after about 640 turns is powered to semiconductor chilling plate 5 by speed-regulating switch, then partly led
Body cooling piece 5 is started to work, and heat is discharged by heat-conducting block 3 and radiator fan 2, and cooling capacity passes to temp probe by cool guiding block 4,
Then vehicle ECU will determine that vehicle is in low temperature environment, open the engine and distributive value, and then idling will rise to about
760 turns, engine is staggered the resonant frequency with vehicle frame, and vehicle abnormal dither (resonance) disappears.
As preferable selection, the function of semiconductor chilling plate 5 can constantly be adjusted by the temperature on driving display screen
Rate, until the temperature of driving display screen is 4 ° or so.Because cool guiding block 4 will not freeze under 4 ° of states, and because low temperature is solidifying
The water droplet of knot can be dripped comparatively fast, will not cause to corrode to itself, guarantee service life.
As common knowledge, vehicle idling rises the rising for necessarily causing oil consumption.It is shown according to car running computer screen, at 760 turns
Under idling mode, vehicle idling oil consumption is about about 0.1L/ hours higher than 640 turns.So because idling increases the oil consumption cost base generated
Originally it can be ignored.
