Engine Idle Speed Control Energy Saver Engine Idle Speed Control Energy Saver, by definition is through a variety of operating conditions to reduce engine idle speed to achieve energy efficiency (fuel economy) purposes.Why is more energy-efficient Japanese cars? There is one very important reason is that most Japanese car engines idling in general are relatively low. For example the Honda CRV, Toyota Corolla, and so the engine idling in 500 r / min or so.While other cars are idle most of the 750 r / min to 1000 r / min. And 99% of the idling of vehicles is not regulated. For example why EFI is also changed after the carburetor but not before saving carburetor cars do? Here, with the size of the idle speed is directly related to! Think we waited for a red light, the traffic jam, the other person, to close when the throttle shifting, as well as cold start, etc., when we do not need so much idle, the engine idle speed is too large will, of course wasted fuel ! Some car cold start idling cars and even up to 1800 rev / min to 2000 r / min.With the introduction of fuel consumption tax, fuel-efficient saving money has become the owner of the most pressing needs. It is understood that currently on the market claims to be able to as many as hundreds of fuel-efficient products, basically in order to fuel additives and devices outside the two main type fuel-saving device. The face of wide variety of fuel-efficient products, the owner who seemed at a loss, do not know what kind of fuel-efficient product selection. In view of this situation, our company developed the engine idle speed automatic fuel-saving device! Wei Di Automobile Technology Co., Ltd. is a the engine speed signal by extracting the water temperature signal, air-conditioning the signal, using the engine idle speed control computer software, according to the actual situation model re-calibration to minimize vehicle idling engine heat, air conditioning idle, cold engine idle speed and reduce the heat car time, so as to achieve energy-saving purposes.A
