Background
The fuel pump is used for sucking fuel from the fuel tank, pressurizing and then delivering the fuel to the fuel supply pipe, and is matched with the fuel pressure regulator to build certain fuel pressure. And the fuel filter is connected in series on a pipeline between the fuel pump and the oil inlet of the throttle body. The fuel filter is used for removing solid impurities such as ferric oxide, dust and the like contained in fuel oil and preventing a fuel oil system from being blocked (particularly a fuel nozzle). The mechanical abrasion is reduced, the stable operation of the engine is ensured, and the reliability is improved. The structure of the fuel oil device consists of an aluminum shell and a bracket with stainless steel inside, and the bracket is provided with a high-efficiency filter paper sheet which is chrysanthemum-shaped to increase the flow area. The electrospray filter cannot be commonly used with an oil filter. Since electronic fuel injection filters are often subjected to fuel pressures of 200-300 KPA, the filter is generally required to have a compressive strength of above 500KPA, whereas chemical fuel filters are not required to have such high pressures. The gasoline filter of the carburetor is positioned at one side of the inlet of the oil delivery pump, the working pressure is smaller, a nylon shell is generally adopted, the gasoline filter of the electronic injection engine is positioned at one side of the outlet of the oil delivery pump, the working pressure is higher, and a metal shell is generally adopted. The filter element of the gasoline filter is mostly made of filter paper, and nylon cloth and polymer materials are also used. But in the structural design of the filter screen system, a single-layer single-channel process is adopted, and a further lifting space is provided for oil absorption and filtration effects.
