Solution Overview
Problem
Conventional filtration systems for internal combustion engines do not effectively address the oxidative degradation of lubricating oils, leading to reduced oil life and increased environmental impact due to ash deposits and emissions.
Innovation Solution
Incorporation of a crystalline solid additive that disperses into the operating fluid at temperatures between 60°C to 160°C, reacting with hydrocarbon free radicals to quench oxidation and reduce ash formation, thereby enhancing oil quality and environmental friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional filtration systems are used without additive, then filtration structure is simple, but oxidative degradation of lubricating oil occurs leading to reduced oil life
Solution Approach 1:
The additive is pre-loaded into the filter element during manufacturing, positioned to dissolve into the lubricating oil as it flows through the filter. This preliminary placement ensures the additive is ready to counteract oxidative degradation from the start of operation, extending oil life without requiring complex external dosing systems.
Solution Approach 2:
The additive acts as an intermediary substance that mediates between the filtration system and the lubricating oil. It dissolves into the oil and chemically reacts with hydrocarbon free radicals and peroxides, preventing oxidative chain reactions that would otherwise degrade the oil, thereby extending oil life without modifying the fundamental filtration structure.
2Object-affected harmful factors
If conventional filtration is used, then system structure is simple, but ash deposits and emissions increase environmental impact
Solution Approach 1:
The additive converts harmful oxidative processes into beneficial outcomes. By reacting with hydrocarbon free radicals and peroxides, it prevents the formation of harmful ash deposits and emissions. The oxidation that would normally create environmental harm is instead harnessed to drive beneficial chemical reactions that protect the oil and reduce harmful byproducts.
Solution Approach 2:
The additive changes the chemical parameters of the lubricating oil by introducing substances that react with oxidizing agents. This alters the chemical composition to reduce ash-forming compounds and emissions, improving environmental performance without requiring changes to the physical filtration structure.
3Stability of the object's composition
If additive is added to filter element, then oxidative stability is improved, but filter element structure becomes more complex
Solution Approach 1:
The filter element is designed to perform multiple functions: mechanical filtration of particles and chemical protection against oxidation. The additive is integrated into the filter structure, allowing a single component to provide both filtration and oxidative stability, rather than requiring separate systems for each function.
Solution Approach 2:
The filter element serves itself by incorporating the additive directly into its structure. As lubricating oil flows through the filter, the additive automatically dissolves and begins protecting the oil, without requiring external dosing systems or additional components. The filter becomes self-sufficient in providing both mechanical and chemical protection.
