汽车空气滤清器（无纺布滤芯）设计标准

以前的往事 · 发表于 9-3-2013 15:24:42

我现在在设计一款空滤器滤芯，是采用无纺布的，我就是想知道关于这个过滤面积怎么计算？谁有无纺布滤芯的一些设计技术标准，谢谢！

以下的资料足够你设计出好的滤清器了
Air Filter Flow Calculations
Chuck Leeper with permission from K&N Introduction
Below is a series of formulas to determine air filter size for a given air flow capacity. Chuck was trouble shooting a problem when he found that air flow he needed was more than his 9" filter could provide. K&N shared this information with him to help trouble shoot his problem.
Formulas
Square inches of filter required for a motor = CID x Maximum RPM / 20839

CFM required for a 4 stroke motor = CID x Maximum RPM / 3456

CFM required for a 2 stroke motor = CID x Maximum RPM / 1728

CFM required for a turbocharged or supercharged motor = Pounds of Boost / 14.7

Add 1.0 to this answer. This relates to #2 and #3

Example: (CID x maximum RPM x #4 ) / 3456 or 1728

To find circumference of a circle multiply diameter by 3.1416

To find diameter of a circle multiply circumference by .31831

CFM Formulas for Filters

Round: Diameter x Height x 6 x 3.14
Flat Panel: Length x Width x 6
Universal Round Taper: (Base + Top) / 2 = A
Take A x Length x 6 x 3.14
Universal Round Straight: Diameter x Length x 6 x 3.14
