Use the Wardli fuel saver to ensure you can save fuel
(Wodeli fuel saver) EFI vehicle temperature control fuel saver
Ward The fuel saver is a fuel-saving product that uses an integrated operational amplifier to expand the signal value of the water temperature sensor, reduce the concentration of the injection mixture, reduce the amount of fuel injection, shorten the warm-up time and reduce the idle speed of the warm-up engine to achieve fuel-saving purposes.
The coolant temperature sensor of an EFI vehicle is an important parameter component for the fuel injection amount of the EFI system. It is a device that uses the principle of changing electrical signals based on changes in engine water temperature to provide signals to the computer to determine the current water temperature. The computer corrects the fuel injection amount based on this signal to achieve different mixture concentrations. Actual measurements show. There is a 40% difference in the amount of fuel injected when the water temperature is above 80 degrees and when the water temperature is below 80 degrees, and the ignition time is also relatively late when the temperature is low. that is. When the water temperature is below 80 or lower, the fuel injection state is rich and the ignition time is late. This is the main factor that makes summer more fuel-efficient than winter. When driving in winter, it takes a long time for the water temperature to reach 80 degrees due to the heating. The optimal operating temperature of the engine is 80~90 degrees. In winter, the engine needs heat preservation rather than heat dissipation! In winter, due to the influence of flowing air, the engine temperature is not easy to maintain between 80 and 90 degrees. The engine will increase the amount of fuel injection and change the ignition advance angle, which will increase your fuel consumption unknowingly.
In order to maintain the temperature in winter, most engines are in small circulation; and external circulation state. And when you turn on the hot air, the cold air in the car flows quickly through the surface of the heat exchanger, which actually adds an efficient radiator to the engine's cooling circulation system! Its effect can be imagined. All in all, fuel consumption in winter is definitely higher than usual, even higher than with the air conditioner on in summer; it is even worse if the hot air is turned on.
In addition, according to the existing EFI engine data, the fuel consumption of the first two kilometers of cold driving is 30-40 liters/100 kilometers, the third to fourth kilometers is 20-30 liters/100 kilometers, and the fuel consumption of the car is 7 to 8 kilometers. Only when the water temperature reaches 60 degrees or above can the theoretical fuel consumption set by the normal manufacturer be 7-9 liters/100 kilometers. The time mileage in cold areas is longer. As commuters who now travel by car, they usually travel a few kilometers or more than ten kilometers. Low water temperature and short-distance driving are the main reasons for high fuel consumption of automobiles.
This device uses the signal of the expanded original water temperature sensor to give the computer an expanded signal value, so that the fuel injection concentration after starting at low temperature and before the water temperature reaches 90 degrees is correspondingly reduced compared to the original injection fuel concentration. At the same time, the warm-up time is shortened and the warm-up idle speed is reduced, thereby achieving the purpose of energy saving.
This device is suitable for various series of electronic injection engines. Such as; electronic injection gasoline engine type, electronic injection diesel engine type. EFI to gas engine. After one year of actual testing, the fuel saving rate is 10-20%, which is equivalent to the oil consumption of a carburetor. The mixture concentration is reduced and exhaust emissions are reduced40. It is the only product that saves fuel by reducing the injection pulse width.
