Many people will find that, under heavy early winter running on the "heat preservation quilt" in recent years gradually been frozen. Special Yu Fan Clutch says the use of the"heat preservation quilt" is to prevent the engine from cold start and cryogenic environments was forced cooling, leading to increase in temperature of trucks, engine wear and fuel consumption increase. Design of fan disappear and engine cooling system which related to the development of.
Fan cooling system three development stages, and the advantages of the multilevel control fan had introduced. Today's special Yu fan clutch to a commonplace talk of an old scholar, continue to talk about the multilevel control fan of engine and vehicle fuel consumption what benefits.
The multilevel control of engine cooling fan energy-saving new concept
As we all know, the engine cooling system fan is the role of the engine to maintain theoperating temperature between 85-95 DEG C the best, let diesel have runenvironment best and keeping the low fuel consumption. In the heat engine management system, fan design experienced three stages of development: rigid fanearly; ordinary silicone oil fan clutch; multistage fan speed at present relativelyadvanced (including electromagnetic fan clutch, clutch fan).
- the traditional rigid fan waste engine power
The traditional rigid fan just blind cool, in two cases, will increase fuel consumption.
1, when the winter heating difficult engine.
2, the engine running at low speed, cooling system temperature by forced cooling.
- conventional silicone oil fan clutch stepless easy damage
Conventional silicone oil fan clutch special margin using double metal spiral feelingbehind thermostat induction radiator air temperature, separation and combined with automatic control fan clutch. Compared with the rigid silicone oil clutch for fan fan, can achieve the temperature controlled speed, low noise compare fuel-efficient, but there are some defects.
1, the silicone oil fan clutch is greatly affected by air temperature, the cooling effect is not stable.
2, the mechanical structure is relatively complex, easy to damage and failure.
- multistage fan speed precise control of the temperature of the engine
Multistage fan speed through the temperature control switch radiator outlet and ECU(or intelligent control unit) control link to achieve the degree of clutch control fan speed. The electromagnetic fan clutch can regulate the level two (idling speed, full speed) and level three (idling adjusting speed, low speed, full speed). The electrically controlled clutch fan speed lifting and the water temperature maintained a linear relationship between the radiator.
Special Yu Fan Clutch said multistage fan speed in the thermoregulation effect and lower fuel consumption has great advantage:
1, according to the temperature of any regulation of wind speed, effectively reduce the fan useless power consumption, saving fuel.
2, cold start engine fast heating, warm effect obviously, reduced wear and cold when the vehicle, reducing the exhaust emission.
3, when the engine cooling fan when needed, fast response, good cooling effect.
