The tag contains the original encryption code, and the information in the tag is read and transmitted to the ECU of the whole vehicle to monitor the authenticity of the filter element and the service life of the filter element, and remind the driver to replace the filter element in time; and each time the car is started, the electronic pump will have an exhaust action to exhaust the air in the fuel filter as much as possible and improve the combustion efficiency; the engine oil return heater contains an alloy memory spring, which can instantly sense According to the oil temperature (open at 8°C and close at 20°), the valve body is opened and closed to allow the high-temperature oil in the engine to enter the crude oil below 20°C to heat the crude oil, thereby improving the filtration efficiency of the fuel. The alloy memory spring responds quickly, has no lag, is durable and not easy to fail. The filter element with three-stage filter screen can more fully filter impurities and moisture, improve the water separation efficiency, and ensure the water separation effect of the entire maintenance mileage. The cylinder integrates the interface with the installation cover, resistive heater, and water level sensor installation. The resistive heater prevents the water separated from the bottom of the cylinder from freezing, resulting in the inability to drain water or even the rupture of the cylinder. It can effectively heat the fuel in the assembly and improve cold start. The water level sensor will transmit a signal to the driver when the water level reaches a certain height to remind the driver to drain water in time. It is more intelligent, improves driving experience, and greatly improves the combustion efficiency of the fuel and the service life of the filter element and the engine.
