Asymmetric Air Supply Manifold for Compact Engine Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In engines, reducing the dimension of the air supply manifold to suppress engine width compromises air supply efficiency.
Innovation Solution
The engine design includes a cylinder head with an intercooler on one end, an air supply manifold, and a cooling piping arranged in a specific width direction, with the intercooler's air and liquid outlets shifted to one end, and the air supply manifold's paths positioned to equalize air supply, allowing for a compact configuration without decreasing air supply efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the dimension of the air supply manifold is reduced to suppress engine width, then the engine width is reduced, but the air supply efficiency decreases
Solution Approach 1:
The air supply manifold is designed with an asymmetric cross-section where the length in the width direction is shorter than the length in the direction intersecting both the row direction and the width direction. This dimensional reconfiguration allows the manifold to fit within a narrower engine width while preserving adequate air supply volume and flow characteristics through extended length in the intersecting direction.
Solution Approach 2:
The air supply manifold employs an asymmetric geometry with unequal dimensions along different axes. Specifically, the cross-section is configured so that the width-direction length is shorter than the intersecting direction length, creating an optimized asymmetric shape that reduces engine width while maintaining air supply efficiency.
2Volume of moving object
If the air supply manifold dimension is reduced, then the engine becomes more compact, but the air supply path becomes insufficient
Solution Approach 1:
The air supply manifold redistributes its volume across different spatial dimensions, with reduced extent in the width direction but maintained or extended extent in the intersecting direction. This dimensional transformation preserves the necessary air supply volume while reducing the overall engine volume through more efficient spatial utilization.
