The invention discloses a fuel oil filtering device, comprising a fuel oil filter, an engine oil supply pipe, an oil tank return pipe and a fixing bracket, wherein the fixing bracket is used for fixing the fuel oil filter on a vehicle frame; the engine oil supply pipe comprises an oil tank return pipe interface and a fuel oil filter fuel interface; the fuel oil filter comprises an oil outlet pipe; the oil tank return pipe interface and the fuel interface of the fuel oil filter are respectively provided with quick-change connectors; the oil tank return pipe is communicated with the oil tank return pipe interface through the quick-change connector; the oil outlet pipe is communicated with the fuel interface of the fuel oil filter through the quick-change connector. The fuel oil filtering device is simple in structure; the oil tank return pipe and the oil outlet pipe are relatively firm in connection, and relatively convenient and fast to install and dismantle due to the quick-change connectors; fuel oil leakage caused by loosening of pipe joints due to vibration is avoided; in addition, the fuel oil filter is capable of filtering different impurities in the fuel oil by adopting a multi-stage filtering mode; the probability that the filter is blocked by impurities is lowered; the fuel oil can smoothly flow into a fuel system.
Description
technical field [0001] The invention relates to a motor vehicle fuel filter device, in particular to a fuel filter device. Background technique [0002] The main function of a fuel filter device is to filter impurities in the fuel to prevent them from entering the carburetor. At present, most engines are equipped with disposable paper filter fuel filters, which are easily blocked by impurities in the fuel and shorten the service life; in addition, when the paper filter is blocked, the fuel flowing out of the filter outlet is reduced. , so that the fuel cannot flow smoothly into the fuel system. [0003] After the fuel is filtered by the filter, it is sent to the engine for combustion. In the traditional fuel supply system, the fuel pressure regulator adjusts the fuel pressure in the engine fuel supply pipe according to the gas pressure change in the intake pipe, so as to ensure a constant fuel pressure difference. However, the fuel pressure in the engine fuel supply pipe i...
