Problems solved by technology

Generally, the high-grade fuel filter has a better filtering effect. This kind of filter uses a multi-layer winding filter method for filtration. The multi-layer winding filter method increases the fuel flow rate compared with the traditional single-layer pleated filter fuel filter paper. and filtration accuracy, but the multi-layer winding filter method uses ordinary fuel filter paper, and its filtration efficiency is still limited

Abstract

The invention relates to oil filter paper and a production process thereof. The production process of the oil filter paper comprises the steps of pulping, pressing, corrugating and drying. The final paper comprises a resin with a weight ratio larger than 0 but equal to or smaller than 8%, a ceramic fiber a weight ratio larger than 0 but equal to or smaller than 5%, and wood pulp fiber with a weight ratio equal to or larger than 87% but smaller than 100%. The oil filter paper is corrugated paper with a longitudinal elongation rate equal to or larger than 12% but equal to or smaller than 17%. Accordingly, the oil filter paper has the advantages of good air penetrability, large filter space, small maximal aperture and high filter accuracy, and can effectively remove impurities in oil, thus improving the quality and the utilization rate of the oil product. The oil filter paper can be used for the oil supply system of an electro-spray device to reduce spray particle and effectively reduce exhaust emission of vehicles and air pollution.

Description

technical field [0001] The invention relates to a fuel filter paper and a production process thereof. Background technique [0002] At present, the oil supply system of the existing car engine in China is usually supplied by an oil pump. Due to the large oil mist particles generated in the cylinder of the oil pump, the exhaust gas of the car contains a large amount of unburned fuel, and the air pollution is serious. In order to save energy and reduce pollution, China Internal Combustion Engine Industry Association, China Association of Automobile Manufacturers, and State Environmental Protection Administration plan to meet Euro III emission standards for cars in major cities by the end of 2007. In order to meet the Euro III emission standard, the original method of fuel injection by the engine oil pump must be changed. For example, the use of electronic fuel injection device for fuel supply can improve the utilization rate of fuel, while the use of electronic fuel injection ...
