Vehicle Intake Pipe Cooling via Travel Wind Guiding Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing engine intake system inefficiencies in cooling the air flowing through the intake pipe due to insufficient vehicle travel wind hitting the intake pipe, particularly when the intake pipe runs around the rear side of the engine, lead to increased air temperature and reduced intake charging efficiency.
Innovation Solution
A travel wind guiding member with a vertical wall portion and inclined portion is positioned to direct vehicle travel wind along the intake pipe, suppressing heat transfer from the engine and concentrating wind flow along the pipe, thereby enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the intake pipe runs around to the rear side of the engine, then the heat transfer from the engine to the intake pipe is suppressed, but the travel wind cannot efficiently cool the air flowing through the intake pipe
Solution Approach 1:
A travel wind guiding member is introduced as an intermediary component between the travel wind and the intake pipe. This guiding member includes a vertical wall portion that directs the travel wind to flow along the intake pipe, and an inclined portion that guides the wind from the front of the vehicle to the rear, ensuring efficient cooling of the intake air while maintaining the pipe's routing around the engine
2Temperature
If the intake pipe is arranged on the lateral side of the engine cover, then heat transfer from the engine is suppressed, but the amount of travel wind hitting the intake pipe is small
Solution Approach 1:
The travel wind guiding member extends in the vehicle longitudinal direction from the front to the rear, utilizing the longitudinal dimension to channel the travel wind along the entire length of the intake pipe. This dimensional approach ensures that sufficient wind quantity reaches the intake pipe even when it is positioned on the lateral side of the engine cover
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
This configuration effectively cools the air flowing through the intake pipe, improving intake charging efficiency by reducing temperature increases and ensuring better air density, thus enhancing engine performance.
Implementation Method 1
the travel wind is guided by the vertical wall portion of the travel wind guiding member in a manner to flow along the intake pipe on the outer side of the separation wall, the air that flows through the intake pipe can efficiently be cooled by the travel wind
Implementation Method 2
the travel wind that is introduced into the engine room spreads on both sides of the engine and flows rearward of the vehicle... the travel wind guiding member with a vertical wall portion and inclined portion is positioned to direct vehicle travel wind along the intake pipe

AI summary
In an engine room, a separation wall is provided between the intake pipe, which runs around to a rear side of the engine from a lateral side of the engine, and the engine. On an outer side of this separation wall, a travel wind guiding member having a vertical wall portion that opposes the separation wall with the intake pipe being therebetween is provided. The travel wind guiding member guides vehicle travel wind that is introduced into the engine room in a manner to cause the vehicle travel wind to flow along the intake pipe on the outer side of the separation wall.
