Supercharged Engine Intake Device Vertical Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddle-ridden type vehicles with superchargers face challenges in reducing air resistance through intake and outlet pipings, leading to decreased engine response and increased turbo lag, as well as difficulties in compactly disposing and mounting intake system components, which results in larger vehicle width and increased manufacturing complexity.
Innovation Solution
The components of the intake system, including the air cleaner, supercharger, and intercooler, are strategically positioned above the engine, with the supercharger at the front and the air cleaner and intercooler arranged side by side, allowing for shorter, linear pipings that reduce air resistance and enable a more compact design, thereby improving engine response and reducing vehicle width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the supercharger and intercooler are dispersedly disposed at the front and rear of the engine, then the components can be positioned according to functional requirements, but the air outlet piping becomes long and air resistance increases
Solution Approach 1:
The patent transitions from a linear front-rear arrangement to a vertical stacking arrangement where the air cleaner, supercharger, and intercooler are disposed above the engine in the vertical direction. This dimensional change allows the components to remain functionally separated while minimizing piping length and air resistance through compact vertical integration.
2Ease of manufacture
If the air cleaner, intercooler and surge tank are separate components disposed around the engine, then each component can be optimized independently, but the vehicle width increases and mounting complexity increases
Solution Approach 1:
The patent merges the air cleaner, intercooler, and surge tank into a single integrated intake device that is disposed above the engine. This consolidation maintains the functional independence of each component while reducing the overall vehicle width and simplifying the mounting process as a single unit.
Solution Approach 2:
The patent utilizes the vertical space above the engine to accommodate the integrated intake device, transitioning from a horizontal spread arrangement that increases vehicle width to a vertical stacking arrangement that compactly houses multiple components without increasing the vehicle's footprint.
3Ease of manufacture
If the air cleaner, intercooler and surge tank are separate components disposed around the engine, then each component can be optimized independently, but the mounting time increases
Solution Approach 1:
The patent combines the air cleaner, intercooler, and surge tank into a single integrated intake device, reducing the mounting process from installing multiple separate components to installing one unified assembly, thereby significantly reducing mounting time while preserving the functional optimization of each component.
4Ease of manufacture
If the air intake piping and air outlet piping are disposed at the side of the engine, then the components can be connected, but the vehicle width increases
Solution Approach 1:
The patent repositions the air intake and outlet pipings from a horizontal side arrangement to a vertical arrangement that passes through the intake device above the engine. This dimensional change allows the components to be connected while eliminating the need for lateral piping extensions, thereby reducing the vehicle width.
