디젤기관(機關)에 있어서의 메타놀의 사용(使用)에 대한 연구(硏究) = A Study on the Use of Methanol in Diesel Engines

다국어 초록 (Multilingual Abstract)

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 curtailment 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.
