Then, the diesel fuel enters the gap between the filter element 23 and the housing 1 through the first oil outlet 14, passes through the filter element 23 from the outer periphery of the filter element 23, enters the oil outlet pipe body 15 through the opening 16, flows out from the second oil outlet, and finally enters the engine through the oil outlet pipe 17. Impurities and water in the fuel are filtered out by the filter element 23, and the water that is filtered out flows downwards to the water storage cavity 29 through the gap between the filter element 23 and the housing I. When the water level in the water storage cavity 29 is higher than the two third pins 18 of the water level alarm, the two third pins 18 are turned on, and the water level alarm sends an alarm signal to remind the driver to discharge water. The driver opens the water discharge valve. Under the positive pressure of the oil pump, the water in the water storage cavity 29 flows upwards sequentially through the second drain pipe 25, the first drain pipe 24, the first drain channel 26, and the second drain channel 28, and then is discharged. When fuel is discharged from the second drain channel 28, it indicates that all water in the water storage cavity 29 is already discharged.
[0024] The second drain pipe 25 is inserted into the lower end of the first drain pipe 24 during assembling, and the second drain pipe 25 and the first drain pipe 24 are connected to the heater and the plug 27 as a whole [0025] In the filter, the heater and a water level sensor are integrally designed, and water is discharged upwards. The diesel filter has a compact structure and a small volume, and resolves the problem of insufficient space of a passenger car and difficulty in the water discharge operation. The heater transfers heat through the upper plate 4 and the lower plate 5 and has a large area. The heater can quickly heat diesel fuel, thereby resolving the problem that wax precipitation of diesel fuel in a low-temperature environment blocks the surface of the filter element 23, resulting in that diesel fuel cannot pass through and cold start is difficult.
