Principle of Plasma Method
- Generation of electrons at the plasma poles by the electrolytic dissociation of high-pressure gas.
- Formation of blue-white flames from the collision of ions and electrons.
- Ionization and smoke-like condition of exhaustion gas of diesel emission.
- Generation of high chemical reactive radicals from the collision of high-energy electrons discharged from the poles with nearby molecules of exhaustion gas.emission
- Disassembly and removal of smoke and exhaustion gas emission through chemical reaction by radicals.
Research Development Achievements
- While the previous method is filtering one collecting and smoke, the plasma method which our company has developed is a direct combustion method, which is excellent for its compact size, durability, and reasonable price, thus ensuring popularity
among people.
- By making great efforts to reduce smoke in diesel vehicles inside and outside the city, our company has successfully reduced the efficiency of management up to 83%, thereby reaching the first goal.
- Although we have already reached 40% of management efficiency for particle materials (PM), we are continuing our research to increase the efficiency.
- Our company is revising our development plan in accordance with the expected addition of domestic regulation about Nitrogen Oxide (NOX).
Smoke Management Efficiency (As of November 1999)
- Test Agency : Korea Institute of Machinery & Materials
- Test Place : Engine Test Room at Korea Machine Research Center
- Test Term: May 2, 1999 - May 28, 1999
Research and Development Plan

Easiness of Putting Research Products to Practical Use
| Division | Products Characteristics |
| Net Price | possible mass production of research products, decrease of net price due to localization of parts. |
| Reliability | use of parts semi-permanent for exhavst gas emission(stainless, steel) |
| Size | the size of the muffler of the car / compact and excellent for noise removal / easy to install as a substituter for a muffler |
| Development Investment | localized parts and possible mass production with small amount of investment |
| Applicability | possible common use of 80% of parts for each model |
| Localization | presently over 95% of parts are localized / 100% localization is possible after one year of mass production. |
| Facile A/S | composition of self-diagnostic circuit / operator can easily discern the fixed condition / parts are composed for each unit, thereby allowing ease of repair / muffler function with the switch on. |
| Facile Supply | possible use of Jit system due to localization / easy assembly / possible mass production |
