Engine Ozone Purification System with Nitrogen Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exhaust gas purification systems that generate ozone from air introduce nitrogen oxides into the exhaust pipe, leading to increased nitrogen oxide emissions.
Innovation Solution
A purification system that separates oxygen and nitrogen from air, generates ozone from the separated oxygen, and supplies it to both the intake and exhaust pipes of an engine, using a membrane for oxygen separation and ultraviolet light for ozone generation, with a supply control device to manage ozone distribution and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ozone is generated from air, then ozone can be supplied to the exhaust pipe for purification, but nitrogen oxides are generated from nitrogen contained in the air and supplied to the exhaust pipe
Solution Approach 1:
The patent extracts only the oxygen component from air using a separation device, removing nitrogen and other unwanted gases. This extracted oxygen is then used for ozone generation, ensuring that nitrogen oxides are not introduced into the exhaust system while maintaining the purification benefits of ozone injection.
Solution Approach 2:
The patent segments the air composition by separating oxygen from nitrogen and other gases. This segmentation allows selective use of oxygen for ozone generation while excluding nitrogen that would form harmful nitrogen oxides, thus resolving the contradiction between purification effectiveness and harmful emissions.
2Object-generated harmful factors
If a separation device is added to separate oxygen from nitrogen, then nitrogen oxide emissions are reduced, but device complexity increases
Solution Approach 1:
The patent introduces a separation device as an intermediary component between air intake and ozone generation. This intermediary device enables the system to achieve low nitrogen oxide emissions by separating oxygen from nitrogen, while the overall system remains integrated and manageable through coordinated control of the separation and ozone generation processes.

AI summary
A purification system for purifying exhaust gas from an engine includes a separation part that separates oxygen and nitrogen contained in air, an ozone generation part that generates ozone from oxygen separated by the separation part, and a supply part that supplies ozone generated by the ozone generation part to an intake pipe and an exhaust pipe of the engine. The purification system includes a supply control device that adjusts an amount of ozone supplied to the intake pipe and an amount of ozone supplied to the exhaust pipe according to a purification rate of exhaust gas of the engine.
