Folded Air Filter Sealing to Reduce Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air filter elements used in internal combustion engines face issues such as engine carbon deposition, oil increase and emulsification, and excessive oil burning due to low-speed operation and turbocharging, leading to power loss and emission problems.
Innovation Solution
An energy-saving and environmentally friendly filter is developed with a filter element body composed of bending parts, where a sealing part, preferably glue, is applied at the bend portion to reduce pressure loss and increase air flow, improving engine power and fuel efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the filter material is made breathable to ensure service life, then the filter can be produced and used, but pressure loss increases and air flow rate decreases
Solution Approach 1:
The patent applies sealing parts (glue or metal) at specific local positions - the bending parts of the filter element - rather than making the entire filter non-breathable. This localized sealing approach blocks only the bending sections while maintaining breathability in the filtering sections, thus reducing pressure loss without significantly compromising air flow rate.
2Loss of energy
If sealing part is applied to block bending part, then pressure loss is reduced and air flow increases, but manufacturing complexity increases
Solution Approach 1:
The sealing part is applied to the bending parts during the manufacturing process, specifically at step S3 where glue is applied to bend portions before the final assembly. This preliminary sealing action ensures that the pressure loss reduction effect is built into the product structure, and the sealing integrates with the existing manufacturing workflow rather than adding separate complex steps.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances air flow and combustion efficiency, resulting in a fuel saving rate greater than 15%, reduced oil consumption, and improved engine performance, while meeting emission standards.
Implementation Method 1
When sonic portions of the bending part is blocked, the pressure loss of the air filter element during operation will be reduced
