Engine Cover Rib and Water Channel for Mid-Engine Air Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mid-engine motor vehicles, managing air and water in the engine room is challenging due to the need to prevent debris and water from entering the air intake system, which is exacerbated by the engine's rearward location, making it difficult to maintain engine cooling and protect engine components.
Innovation Solution
An air and water management system that includes an air opening with a rib forming a gutter on the engine cover to block debris and a water channel with a drain to direct water away from the engine room, ensuring clean air intake and effective water drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If open vents are applied to direct air into the mid-engine engine room, then air intake efficiency is improved, but debris and water may be directed into the air intake system
Solution Approach 1:
The air opening is segmented into multiple functional zones: an upper portion that allows air intake while blocking debris and water, and a lower portion that provides additional airflow. This segmentation enables the system to simultaneously achieve high air intake efficiency while preventing contamination of the air intake system.
Solution Approach 2:
The air opening structure acts as an intermediary element between the external environment and the engine room. Its specific geometry and positioning create a filtering effect that mediates between the need for open airflow and the need to block harmful factors like debris and water.
2Reliability
If the engine is located in the middle of the vehicle for improved handling and suspension efficiency, then vehicle performance is improved, but engine cooling becomes more difficult
Solution Approach 1:
The air opening is positioned in the upper portion of the engine room structure, utilizing vertical space rather than only horizontal airflow paths. This dimensional change allows cool air to be drawn from above the engine, providing effective cooling while maintaining the mid-engine layout for optimal vehicle handling and suspension performance.

AI summary
An air and water management system for a motor vehicle is disclosed. The system includes an air opening allowing air to enter the engine room on a side of the motor vehicle, an engine cover covering at least one component associated with the engine of the motor vehicle, a rib extending from a top side of the engine cover creating a gutter on the engine cover between the rib and a side of the engine room, a water channel formed integrally in the engine cover adjacent and laterally inward of and parallel to the rib and including a drain longitudinally to the rear of the motor vehicle at a rearward portion of the water channel. Air entering the air opening flows over the rib and into the engine room of the motor vehicle. The rib blocks debris that enters the air opening from flowing into the engine room.
