디젤기관(機關)에 있어서의 메타놀의 사용(使用)에 대한 연구(硏究)
이충호 ( Lee Choong Ho ),김양술 ( Kim Yang Sool ),이길우 ( Lee Kil Woo ) 한국농공학회 1987 韓國農工學會誌 : 전원과 자원 Vol.29 No.1
Through the result of examinations and its study, such conclusions as described below can be found; 1. If methanol is made to flow from an inlet pipe, due to the latent heat of vaporization in methanol, the intake and exhaust temperatures are getting lower in comparison with the case of injection with diesel oil only. 2. If methanol is made to flow from an inlet pipe, the intake temperature is getting lower, nevertheless, there is not a great change in particular for the volume of the inhaled air, which is caused by the volume of the inhaled air gets damping with the partial pressure in methanol. 3. When the operation goes on under the slight load with the whole volume of the inhaled diesel oil, the methanol-air mixing unit gets remarkably increased in the heat rate due to an extremely weak combustion making progress and taking the initiative of the bad methanol for ignition. 4. Keeping up the volume of diesel oil needed to 3/4-load operation, and in case that the output of more than, that depends upon the intake of methanol, it is favorable to a heating economical aspect. 5) Methanol itself is bad in ignition and a diesel engine cannot be driven with methanol only, but while gushing out a considerable volume of diesel oil, methanol is able to make efficient use as subfuel for a diesel engine in such a manner as letting inhaled through and from the inlet pipe, and it can bring the effective curtail ment of fuel relevant to pet volume, however, if the inhaled volume of methanol is excessive, there might happen a diesel knock. 6. In case that the cost of diesel oil rises a little, methanol as sub-fuel, would have a hight quality in economy.

水中高電壓放電에 依한 壓力波의 發生에 關한 實驗的 硏究
金良述 홍익대학교 산업기술연구소 1993 産業技術 Vol.2 No.-
This paper is will be a helpful to understand the underwater discharging through analysis of shock pressure wave by high-voltage discharging and obtained following results for experiment under various discharging condition. 1. The electrical energy between electrodes is seen to the generation of the most high-first pressure wave, second one and third one with reflective wave. 2. The shock pressure wave is not changed the wave's form by discharging condition but peek value of pressure wave is influenced. 3. It is possible to calculate shock energy for first pressure wave with a scheme-integral method by measurement of pressure wave.
