Embodiment 1

[0054] This embodiment provides a fuel filter, such as figure 1 with figure 2 As shown, the fuel filter includes a filter body 1 , a drain cup 2 and a heat exchanger 3 .

[0055] The filter body 1 can filter out impurities and water in the fuel, and the fuel flow route is as follows: figure 2 As shown by the arrow in the figure, after passing through the ring-shaped filter element 10, it is filtered from the outside to the inside layer by layer, and the finally filtered clean fuel flows out from the oil outlet channel on the central axis of the filter body 1, and the water filtered out by the filter element 10 and large-mass impurities sink into the water collection chamber of the drain cup 2, and the heat exchanger 3 extends from the drain cup 2 into the filter body 1, and the engine high-temperature coolant circulates in the heat exchanger 3.

[0056] Such as Figure 1-Figure 5 , the heat exchanger 3 includes a water inlet section 3A, a water outlet section 3B and a hea...

Embodiment 2

[0073] This embodiment provides a fuel filter, such as figure 1 with figure 2 As shown, the fuel filter includes a filter body 1 , a drain cup 2 and a heat exchanger 3 .

[0074] The filter body 1 can filter out impurities and water in the fuel, and the fuel flow route is as follows: figure 2 As shown by the arrow in the figure, after being filtered layer by layer from the outside to the inside by the annular filter element 10, the finally filtered clean fuel flows out from the oil outlet channel on the central axis of the filter body 1, and the water filtered out by the filter element 10 and large-mass impurities sink into the water collection chamber of the drain cup 2, and the heat exchanger 3 extends from the drain cup 2 into the filter body 1, and the engine high-temperature coolant circulates in the heat exchanger 3.

[0075] Such as Figure 1-Figure 5 , the heat exchanger 3 includes a water inlet section 3A, a water outlet section 3B and a heat exchanger main body ...

Abstract

The invention belongs to the technical field of automobile fuel oil supply systems, and discloses a fuel oil filter which comprises a filter body. The water discharging cup is connected to the bottom of the filter body, and a water collecting cavity is formed in the water discharging cup; a water inlet section and a water outlet section of the heat exchanger respectively penetrate through the water discharging cup and are communicated with the outside, and a heat exchanger main body between the water inlet section and the water outlet section in the heat exchanger is arranged between the filter body and the water discharging cup in a reciprocating disc folding manner and a close-to-whole-circle disc folding manner. When fuel oil is unfrozen, impurities and water in the fuel oil are filtered out through the filter body, the large-mass impurities and water sink into the water discharging cup, engine high-temperature cooling liquid circulates in the heat exchanger, and therefore the fuel oil in the filter body and the fuel oil and water in the water discharging cup are heated, and the situation that an electric heating device is used for heating unfrozen water and 0 # diesel oil in winter is avoided; storage battery electric energy is saved, and automobile electricity shortage is relieved.

Description

technical field [0001] The invention relates to the technical field of automobile fuel supply systems, in particular to a fuel filter. Background technique [0002] During the working process of the engine, the fuel filter is connected in series in the oil supply pipeline to filter the impurities and water contained in the fuel, prevent the fuel injector and other precision components in the fuel system from clogging, reduce mechanical wear, ensure the stable operation of the engine, and improve reliability. [0003] In winter, the liquid in the water cup of the fuel filter will freeze, making it impossible to release water. The solution on the market is to heat and thaw with an electric heating device, which requires continuous consumption of electric energy, and more and more electrical appliances are used in vehicles. Under the current development trend, coupled with the severe battery loss in winter, there will be problems of vehicle power shortage and battery power sho...
