Outdoor Air Intake Layout for Indoor Engine Heat Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing combustion air and cooling air to engines and motors indoors result in significant energy loss and air draught, as they rely on heated indoor air, leading to increased heating costs and discomfort due to temperature drops and air flow issues.
Innovation Solution
A method involving an air intake box and channel system that directs outdoor air directly to the engine or motor, bypassing indoor air to prevent heat loss and air draught, using a tightly fitted air intake box and channel system that can be supported and equipped with a suction fan for efficient airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If heated indoor air is used for combustion and cooling, then the engine operates normally, but significant energy is lost and heating costs increase
Solution Approach 1:
The air supply system is segmented into separate indoor and outdoor air sources. The invention divides the air intake function by providing dedicated outdoor air channels for combustion and cooling air, separating it from the indoor air that would otherwise be consumed by the engine.
Solution Approach 2:
An intermediary air channel system is introduced to transport outdoor air directly to the engine air intake. This intermediary structure (air channels with releasable connections) mediates between the outdoor air source and the engine, preventing direct interaction between indoor air and engine air consumption.
2Ease of operation
If indoor air is consumed by the engine, then combustion and cooling are maintained, but air draught and temperature drops occur in the room
Solution Approach 1:
The air supply is segmented into outdoor source for engine needs and indoor source for room maintenance. By providing separate air channels from outdoors, the system segments the air flows to prevent the harmful draught effect while maintaining engine operation.
Solution Approach 2:
The harmful effect of indoor air consumption is eliminated by extracting the air supply function from the indoor environment. The invention takes out the air intake from the indoor space and relocates it to an outdoor source, thereby removing the cause of air draught and temperature drops.
3Loss of energy
If outdoor air channels are installed for engine air supply, then energy loss is reduced, but device complexity increases
Solution Approach 1:
The air channel system is made dynamic and adaptable through releasable connections. The channels can be adjusted, connected, or disconnected as needed, allowing the system to adapt to different installation environments and engine positions, thereby reducing the perceived complexity.
Solution Approach 2:
The system allows for parameter changes in the air channel configuration, such as adjustable channel lengths, connection points, and flow rates. This flexibility enables the system to be optimized for different situations without requiring a completely complex fixed design.
