Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment 1:A kind of auto idle speed abnormal dither adjusting apparatus of based semiconductor cooling piece, as Figure 1-3, including shell 1, in shell, 1 is disposed with radiator fan 2, heat-conducting block 3, semiconductor chilling plate 5 and cool guiding block 4 to its structure under upper;
Described radiator fan 2, heat-conducting block 3, semiconductor chilling plate 5 and cool guiding block 4 are fastened and connected by bolt;
The blind hole 8 for holding automotive temp probe it is provided with bottom described cool guiding block 4.
Going back lobe 6 on described shell 1, the centre of lobe 6 has colligation hole 7.
As a kind of mode adjusting semiconductor chilling plate 5 power, described semiconductor chilling plate 5 can be connected with speed-regulating switch. Adjust the mode of semiconductor chilling plate 5 power as another kind, described semiconductor chilling plate 5 can be connected with speed governing chip and on and off switch.
No matter adopting which kind of mode, speed-regulating switch, speed governing chip and on and off switch all should be installed in driver's cabin.
Described radiator fan 2 is interference fit with shell 1. During maintenance, firmly press radiator fan, then shell just can come off again by Bolt dismantling.
When this device is installed, utilize Plastic Bandage to run through colligation hole 7, then this device is tied up in enging cabin, then the temperature probe in enging cabin is inserted blind hole 8.
Essence of the invention is that:
The basic reason of auto idle speed abnormal dither is in that electromotor frequency under room temperature idling mode and vehicle frame natural frequency are close, causes vehicle resonance to cause. Under resonance state, external OBD detects, because vehicle motor runs well, and sufficient combustion, it is in normal condition, so any DTC will not be shown, therefore electromotor and vehicle frame all will not be keeped in repair by 4S shop and Railway Car Plant business. Again because engine idle is good, so changing 97, No. 98 gasoline, using gasoline additive, changing complete synthesis machine oil, heavy-bodied oil and replacing engine support and cannot inherently solve problem. Essential problem is still in that how to improve vehicle idling.
In this device, use procedure is as follows:
Vehicle ignition, engine idle is about 1300 turns, travels slowly, and vehicle water temperature rises, and oil temperature rises, and idling declines. Idling steady is (namely idling is normally rear) after about 640 turns, powered to semiconductor chilling plate 5 by speed-regulating switch, then semiconductor chilling plate 5 is started working, heat is discharged by heat-conducting block 3 and radiator fan 2, and cold passes to temperature probe by cool guiding block 4, then vehicle ECU will judge that vehicle is in low temperature environment, open the engine and distributive value, then idling will rise to about 760 turns, and electromotor staggers the resonant frequency with vehicle frame, and vehicle abnormal dither (resonance) disappears.
As preferably selecting, it is possible to by the temperature driven a vehicle on display screen, constantly adjust the power of semiconductor chilling plate 5, until the temperature of driving display screen is about 4 °. Because under 4 ° of states, cool guiding block 4 will not freeze, and because the water droplet of cryogenic temperature condensation can comparatively fast drip, self will not be caused corrosion, it is ensured that service life.
As known general knowledge, vehicle idling rises and necessarily causes the rising of oil consumption. Showing according to car running computer screen, under 760 turns of idling modes, vehicle idling oil consumption is about high than 640 turns when about 0.1L/ is little. So being substantially negligible because idling raises the oil consumption cost produced.
Again because the substantially deception car running computer of this device makes it improve engine idle, and compressor of air conditioner does not start acting, therefore analyzes theoretically, and the power of automobile is substantially without there being loss, and actual driving impression is also such.
