Problems solved by technology

When the water content in the fuel is too high, it can cause the following problems: promote the corrosion of iron parts and aluminum parts in the fuel injection system; cause cavitation and cause the top of the injector to fail; reduce the lubricating performance of the fuel, resulting in fuel injection wear of filter and pump plungers; nourishes the growth of microorganisms that can clog filters at the oil / water interface
[0003] However, due to the variety of fuels on the market, the water content in most fuels exceeds the standard, resulting in a high failure rate of the fuel system

Abstract

The embodiment of the invention discloses a fuel filter and fuel system of an engine and a fault detecting device. The fuel filter of the engine comprises a filter body, a water collecting cup, an electromagnetic valve, a water-in-oil sensor, a timer and a controller; the water collecting cup is connected with the filter body, and the bottom of the water collecting cup is provided with a drainageport; an inlet of the electromagnetic valve is communicated with the drainage port of the water collecting cup; the water-in-oil sensor is arranged in the water collecting cup; the timer is used for timing; a first input end of the controller is electrically connected with the water-in-oil sensor, a second end of the controller is electrically connected with the timer, a first output end of the controller is electrically connected with a control end of the electromagnetic valve, the controller is used for controlling a valve body of the electromagnetic valve to be switched on when the water level of the water collecting cup is higher than a preset water level and controlling the valve body of the electromagnetic valve to be switched off when the water level of the water collecting cup is lower than the preset water level, and the accumulating time of the switch-on of the valve body of the electromagnetic valve is obtained by controlling timing of the timer. By means of the technical scheme, the water content of fuel in the fuel system of the engine can be detected.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine fuel filter, a fuel system and a fault detection device. Background technique [0002] The water content in fuel is an important index to evaluate the quality of fuel, and plays a vital role in the performance of the fuel system of the engine and the service life of parts. When the water content in the fuel is too high, it can cause the following problems: promote the corrosion of iron parts and aluminum parts in the fuel injection system; cause cavitation and cause the top of the injector to fail; reduce the lubricating performance of the fuel, resulting in fuel injection filter and pump plunger wear; nourishes the growth of microorganisms that can clog filters at the oil / water interface. [0003] However, due to the variety of fuels on the market, the water content in most fuels exceeds the standard, resulting in a high failure rate of the fuel system. In particular...
