Dongfeng well-off car has a high idle speed.

Fuel-saving semi-automatic idle motor is produced by Jiamusi Dapeng Automobile Fuel-saving Technology Development Center. Telephone number 0454-8609498 can save up to 10%- 15%. Manual idle speed adjustment has the function of preheating the idle speed of high idle air conditioner. It is the best fuel-saving, fuel-saving and idling repair product for D-type EFI engines such as 372, 376, 462, 465, 468, 47 1, 474, 477, 479, 4G*, 4Y and 8A. It is also the best substitute for the idle motor in the above EFI engine. It is the best way to repair the high idle speed, slow idle speed recovery, idle speed wheezing, no idle speed and too fast idle speed of EFI engine. And save fuel by reducing idle speed (because idling for 3 minutes is equivalent to driving a kilometer). The fuel saving can reach 10%- 15%. At the same time, it has the adjustable functions of warm-up and high idle air conditioning. So as to achieve the purposes of repairing idle speed and saving fuel. Idle motor is an element to control the idle speed of EFI engine. It is also the component with the highest failure rate of EFI engine. However, some idle faults are difficult to deal with and belong to difficult faults, because idle working condition is a special working condition and requires a strong mixture. In use, due to various reasons of sensors and systems, it is difficult for ECU to reach the set idle speed range. So the idle speed is often too high. There are many idle problems such as unstable idle speed, slow idle speed return, and too fast idle speed. Resulting in a waste of energy. In all boycott cars, the fuel waste caused by idle speed is 100%. Once there is a problem, it is difficult to solve it. After years of research and practice, the center has designed and developed an automobile gas idle energy saver (fuel-saving semi-automatic idle motor), which can not only adjust the engine idle speed conveniently, but also repair the fuel waste problems such as high idle speed, idle wheezing and slow idle speed recovery of D-type EFI engine. So as to achieve the purposes of repairing idle speed and saving fuel. Because this device is an external modification of the system, neither the warm-up nor the high idle speed of the air conditioner is controlled by computer. In this respect, the device adds external control systems for preheating high idle speed and air conditioning high idle speed. In order to further achieve the purpose of fuel saving, this device also designs an adjustable device for warm-up and air conditioning at high idle speed. Users can adjust the speed of high idle speed of warm-up machine and high idle speed of air conditioner according to the specific situation and needs of local climate conditions. The device is also the only adjustable product of EFI engine at present when air conditioning is warm-up and high idle speed. So as to further achieve the purpose of saving oil. The device is suitable for D EFI engines such as 372, 376, 462, 465, 468, 47 1, 474, 477, 479, 4G*, 4Y, etc. Its idling speed is controlled by automatic stepping motor. Such as: mini-cars, Changan 4500, Li Xia, Li Xia 2000, Geely series, Chery series, Fule, BYD series, Yun Qi, Huapu, pickup truck, Lubao, Lifan, China, Buick, battle flag, horse racing, Saibao, Peugeot, Haval, Jinbei Bread, QQ, Alto, Citroen, Haima and Big Dipper. Users: high idle speed and oil consumption, unstable idle speed, slow idle speed return, idle speed wheezing, idle speed jumping, too fast idle speed, too long warm-up time, gear shifting or clutch rising during driving, starting normal refueling idle speed 1500 or above, too low idle speed, no idle speed, idle speed problems, and it is invalid to replace the idle motor and throttle assembly. Once the above phenomena are used, it is guaranteed to save fuel in maintenance. At the same time, it is also an effective fuel-saving method in urban traffic jams.
