Solution Overview
Problem
Existing air cleaner systems for internal combustion engines are costly and inefficient in removing debris, as they often require frequent replacement or modification of components, and existing scavenging methods either rely on expensive muffler modifications or bulky suction fans.
Innovation Solution
An air cleaner scavenging kit that includes a conduit connected to an air-generating component, directing a stream of air into a scavenging conduit to generate suction pressure and remove debris, utilizing a nozzle to create a Venturi effect and efficiently clear accumulated particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a scavenging conduit with a cavity connected to exhaust mufflers is used to generate suction pressure, then debris removal is improved, but the device complexity and cost increase due to muffler modification
Solution Approach 1:
The invention extracts the suction pressure generation function from the exhaust muffler system and relocates it to the scavenging conduit itself by forming a cavity within the scavenging conduit that communicates with the exhaust system, eliminating the need to modify the muffler
Solution Approach 2:
The scavenging conduit acts as an intermediary component that connects the air cleaner to the exhaust system, using the exhaust gas flow as a mediator to generate suction pressure for debris removal without requiring direct modification of the exhaust muffler
2Productivity
If a suction fan is connected to the scavenging conduit to remove dirt particles, then debris removal efficiency is improved, but the device complexity and bulk of the engine envelope increase
Solution Approach 1:
The invention enables the scavenging system to be self-powered by utilizing the engine's own exhaust gas flow to generate suction pressure through the cavity design, eliminating the need for an external suction fan and reducing engine envelope bulk
Solution Approach 2:
The invention uses pneumatic principles by harnessing the kinetic energy of exhaust gases flowing through the cavity in the scavenging conduit to create a pressure differential that generates suction for debris removal, replacing the need for mechanical fan-driven suction
3Volume of moving object
If the cavity in the scavenging conduit has a narrow cross-section, then the structure is compact, but it becomes susceptible to being filled with debris
Solution Approach 1:
The invention introduces a movable flap or valve mechanism within the cavity that dynamically opens and closes based on pressure differential, allowing the cavity to maintain a compact size while preventing debris accumulation by closing the opening when debris approaches
Solution Approach 2:
The invention changes the operational parameters of the cavity by using pressure differential control to vary the effective opening size, maintaining a small physical volume while dynamically adjusting the functional opening to prevent debris filling

Function Achieved in This Case
The solution effectively removes debris from air cleaners without the need for costly modifications or additional components, maintaining the air cleaner's efficiency and reducing operational costs, especially in dirty environments.
Implementation Method 1
The nozzle directs the air towards the exhaust end of the scavenging conduit, the air generating a suction pressure at the first end portion of the scavenging conduit connected to the air cleaner
Data Source
AI summary
The present disclosure provides a method and apparatus for removing debris from an air cleaner of an internal combustion engine. The method includes receiving a flow of air from a source of air flow associated with an internal combustion engine at a first end portion of a conduit and passing the flow of air towards a second end portion of the conduit. The method also includes passing the flow of air into a scavenging conduit of the air cleaner towards an exhaust end of the scavenging conduit and creating a suction pressure at an end of the scavenging conduit connected to the air cleaner. The suction pressure results in a drawing in of the debris from the air cleaner.
