Compact Air Intake Device for Turbocharged Engine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of turbocharger technology in internal combustion engines poses challenges in arranging cabin space due to the complexity and size of the air intake system, necessitating a more compact structure to enhance engine performance.
Innovation Solution
An air intake device is designed with a compact structure, featuring a supercharger connected to the exhaust port, a connection tube, an intercooler located above the cylinder head, and an intake manifold, along with a flat throttle valve positioned between the intercooler and intake manifold, which reduces the overall height and length of the system, preventing water vapor accumulation and corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If turbocharger technology is integrated to improve engine performance, then engine power and efficiency are enhanced, but the air intake system becomes more complex and occupies more cabin space
Solution Approach 1:
The patent merges the intercooler with the intake manifold into an integrated assembly. The intercooler is positioned above the cylinder head and directly connected to the supercharger, while the intake manifold is formed as part of the same structure. This combination eliminates the need for separate post-pressure tubing and reduces the number of components, thereby maintaining engine performance enhancement from turbocharging while reducing system complexity and cabin space occupation.
2Ease of operation
If traditional air intake system arrangement is used, then all components can be connected, but the overall height and length of the system increase, occupying more space
Solution Approach 1:
The patent repositions the intercooler in the vertical dimension by placing it above the cylinder head, rather than arranging it horizontally in the traditional manner. This vertical arrangement allows the intercooler to be integrated with the intake manifold structure, reducing the horizontal footprint and overall system length. The compact design maintains all necessary component connections while significantly reducing the volume occupied by the air intake system in the cabin space.
