Problems solved by technology

However, if the water at the bottom of the tank is not pumped out regularly, the water level at the bottom of the tank will become higher and higher, eventually causing the suction port of the oil pump to pump the water at the bottom of the tank when refueling.
[0004] After the car is filled with this kind of water-mixed fuel, if the water is not filtered out by the filter and enters the combustion chamber, the engine will run unstable and produce violent knocking, and the muffler will "fire" and cause damage to the engine

Abstract

The invention provides a fuel moisture content detection device, belongs to the technical field of automobile refueling, and solves the problem of injection of fuel mixed with water during refueling of the conventional automobile. The fuel moisture content detection device comprises a control module, a prompting module and a moisture detector, wherein the moisture detector can detect moisture content in fuel; and both the moisture detector and the prompting device are connected with the control module. The device has the advantages that: the fuel moisture content detection device is arranged at an automobile refueling port, so the moisture content of the fuel can be monitored during the refueling, the fuel quality of an automobile is guaranteed to keep an automobile owner reassured, the damage to the automobile by water included in the fuel is reduced, the driving safety is improved, and the humanized design of the automobile is embodied.

Description

technical field [0001] The invention belongs to the technical field of automobile refueling, and relates to a detection device, in particular to a device for detecting the water content in fuel. Background technique [0002] Many car owners have encountered the situation that the fuel refilled at the gas station contains water, and there are often reports that after the car is refueled at the gas station, the fuel stalls halfway due to the water in the fuel. [0003] In the oil tank of the gas station, there is water at the bottom of the tank. The water is in the process of transporting the oil from the ship to the oil depot, and then pulling it to the oil station by tanker. Due to the reason of the storage and transportation container or the breathing of the oil, it will inevitably absorb water, and finally in the oil tank of the oil station. The smaller the area, the more it accumulates. Since the oil is relatively light, the water will eventually settle at the bottom of...
