4기통 전기점화기관의 혼합기 불균일 분배가 배기가스에 미치는 영향
진성호,박경석 경희대학교 환경연구소 1993 環境硏究 論文集 Vol.4 No.-
The exhaustion of gasoline engine is related with constitution of mixture, so lean mixture which is for fuel economy should be completely burned as much as possible. But much of supply fuel clings to intake manifold inner wall in a carburetor type engine. Accordingly, it causes nun-uniform mixture and nun-uniform fuel distribution. In this study, variation of fuel air ratio, amount of emission is measured. The effect of fuel film in intake manifold on mixture distribution is studied.

The exhaustion of gasoline engine is related with constitution of mixture. so lean mixture which is for fuel economy should be completely burned as much as possible. But, in reality, lean mixture put down engine power. Accordingly, it is remains that lean mixture and engine performance are combined. In this study, variation of air-fuel ratio, combustion characteristics is measured. The effect of air-fuel ratio on combustion characteristics and engine power in gasoline engine is studied.

Planar images of OH and $O_{2}$ with tunable KrF excimer laser which has a) 0.5 $cm^{-1}$ / linewidth, b) 0.5 nm tuning range, c) 150 mJ pulse energy, and d) 20 ns pulse width are obtained to determine spatial distributions of OH and $O_{2}$ in premixed $C_{3}$H$_{8}$ /O$_{2}$ flame. The technique is based on planar laser induced pre-dissociative fluorescence(PLIPF) in which collisional quenching is almost avoided because of the fast pre-dissociation. Dispersed LIPF spectra of OH and $O_{2}$ are also measured in a flame in order to confirm the excitation of single vibronic state of OH and $O_{2}$, OH and $O_{2}$ are excited on the P$_{2}$(8) line of the $A^{2}$.SIGMA.$^{+}$(v'= 3)-X$^{2}$.PI.(v'||'||'&'||'||'quot;= 0) band and R(17) line of the Schumann-Runge band B$^{3}$.SIGMA.$_{u}$ $^{[-10]}$ (v'= 0)- X$^{3}$.SIGMA.$_{g}$ $^{[-10]}$ (v'||'||'&'||'||'quot;= 6), respectively. Dispersed OH and $O_{2}$ spectra show an excellent agreement with simulated spectrum and previous works done by other group respectively. It is confirmed that OH widely distributed around flame front area than $O_{2}$.

Central diabetes insipidus is a polyuric disorder that results from a lack of sufficient ADH to effect appropriate concentration of the urine for water conservation. It is divided into primary and secondary diabetes insipidus. The majority of secondary diabetes insipidus is caused by operation, neoplastic lesions of the pituitary and hypothalamus and head trauma. Secondary diabetes insipidus complicated with tuberculous meningitis is extremely rare. There have been several reports on diabetes insipidus but no reports on the disorder associated with tuberculous meningitis in Korea. We reported a patient of 38 year old male who developed diabetes insipidus during treatment of tuberculous meningitis and active pulmonary tuberculosis. Tuberculous meningitis was documented by clinical features, laboratory findings and therapeutic response, even though AFB smear of the cerebrospinal fluid was negative in the patient. Water deprivation and pitressin injection test revealed complete type of diabetes insipidus. We have followed this patient's status of diabetes insipidus up for one half year and he has been on 5 units of pitressin tannate in oil every 3 to 4 days. We think his status of diabetes insipidus in permanent.
