Compact Cyclone Separator for Engine Intake Air
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cyclone separators for internal combustion engine intake air are large and complex, requiring separate dust collecting chambers and multiple suction devices, which complicates their design and reduces separation efficiency.
Innovation Solution
A compact separating device comprising two cyclone cells that rotate intake air streams in opposite directions, combining their exhaust streams into a single stream for efficient particle separation, eliminating the need for separate dust collecting chambers and simplifying the design by using a single suction device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple cyclone cells are used to improve separation capacity, then the separation efficiency increases, but the device size and structural complexity increase
Solution Approach 1:
The patent combines multiple cyclone cells into a single integrated housing structure, merging what would traditionally be separate devices into one compact unit. The housing contains multiple cyclone cells that share common structural elements, reducing overall device complexity while maintaining high separation capacity through parallel processing of multiple air streams
2Productivity
If a dust collecting chamber is added to contain particles, then particle collection improves, but the device size and manufacturing complexity increase
Solution Approach 1:
The dust collecting function is merged into the existing housing structure rather than being added as a separate chamber. The housing serves dual purposes: containing the cyclone cells and collecting particles, thereby eliminating the need for additional dust collecting chambers and simplifying manufacturing
3Productivity
If multiple suction devices are used to handle exhaust streams, then exhaust removal efficiency improves, but the device complexity and cost increase
Solution Approach 1:
Multiple exhaust streams from different cyclone cells are merged into a single common exhaust stream that exits through one outlet. This allows a single suction device to handle all exhaust gas removal, reducing the number of components while maintaining efficient exhaust removal through the combined flow

AI summary
A separating device (3) for separating particles from an intake air (2) of an internal combustion engine, comprising two cyclone cells (5, 6) which are designed to cause two raw air streams (7, 8) containing the intake air (2) to rotate oppositely and a discharge device (49) which is designed to guide an exhaust air stream (35, 36) containing the particles tangentially away from a respective cyclone cell (5, 6) and to combine the exhaust air streams (35, 36) to a common exhaust air stream (53).
