Reed Valve Anti-Reversion System for Engine Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internal combustion engines face the issue of reversion, where exhaust gases flow backwards, contaminating the intake charge, leading to reduced power, efficiency, and poor idle quality, especially at low RPM, and existing reed valves are not suitable for larger engines due to pressure-related failures.
Innovation Solution
A reed valve system is designed to be implemented in various internal combustion engines, including four-stroke and six-stroke engines, with a unique configuration that allows its application in engines of different types and sizes, placed in the intake tract to prevent reversion by managing pressure differences effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reed valve is used to prevent reversion, then fuel efficiency and power output are improved, but the valve may fail under high pressure conditions in larger engines
Solution Approach 1:
The patent changes the material parameters and geometric parameters of the reed valve to withstand higher pressures. This includes using higher strength materials and optimizing the valve thickness and dimensions to prevent failure under high pressure conditions in larger engines while maintaining the anti-reversion function.
Solution Approach 2:
The patent employs composite material construction for the reed valve, combining materials with different properties to achieve both flexibility for anti-reversion operation and sufficient strength for high pressure tolerance. This allows the valve to bend properly at low pressures while resisting failure at high pressures.
2Device complexity
If exhaust gases are allowed to flow backwards during reversion, then the system is simpler, but power output and fuel efficiency are reduced
Solution Approach 1:
The patent extracts the anti-reversion function from the main intake system by using a separate reed valve mechanism. This allows the exhaust gases to be prevented from flowing backwards into the intake charge without complicating the overall intake system design, thereby maintaining power output and fuel efficiency.
Solution Approach 2:
The reed valve acts as an intermediary element between the exhaust side and the intake charge. It selectively opens to allow fresh charge in while preventing exhaust gases from flowing backwards, thus protecting the intake system without requiring complex active control mechanisms.
3Speed
If a reed valve is made more flexible to open easily, then responsiveness is improved, but the valve may fail under high pressure
Solution Approach 1:
The patent optimizes the geometric parameters of the reed valve, including thickness, width, and length, to achieve the right balance between flexibility and strength. The valve is designed with sufficient flexibility to open quickly in response to pressure changes while having adequate strength to withstand high pressure without failure.
Solution Approach 2:
By using composite materials with tailored properties, the patent achieves a reed valve that is flexible enough for rapid opening response yet strong enough to withstand high pressure loads. The composite construction allows different regions of the valve to have different stiffness characteristics.
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
The reed valve system effectively eliminates reversion, enhancing fuel efficiency, power output, and responsiveness, allowing for increased torque and horsepower at lower RPM without moving parts, and is applicable across multiple engine types and applications.
Implementation Method 1
Reed valves function by closing and/or opening under pressures on a particular face and/or side of the valve
Implementation Method 2
As the piston, in the cylinder of a high performance engine, rises a vacuum effect is created in the crankcase. Then, as the piston descends, the pressure within the crankcase rises. In this way, there is a pressure difference which causes the valve to open
