Ethylene glycol is a widely used and readily available substance. Ethylene glycol ingestion does not cause direct toxicity; however, its metabolites are highly toxic and can be fatal even in trace amounts. Poisoning is best diagnosed through inquiry, but as an impaired state of consciousness is observed in most cases, poisoning must be suspected when a significantly elevated osmolar gap or high anion gap metabolic acidosis is found in blood tests. Hemodialysis and alcohol dehydrogenase inhibitors such as ethanol and fomepizole are a part of the basic treatment, and timely diagnosis and treatment are crucial because any delays can lead to death. However, there are few reported cases in Korea, and no report on the use of fomepizole. Herein, we report a case of acute renal failure caused by ethylene glycol poisoning that was treated with fomepizole and hemodialysis and present a literature review.
소형디젤엔진용 E-EGR 밸브의 개발 및 차량적용에 관한 실험적 연구
송창훈,정용일,차경옥 한국에너지학회 2002 에너지공학 Vol.11 No.3
본 연구에서는 유니크에서 개발된 E-EGR 밸브의 특성을 분석하였으며, 차량적용의 가능성을 평가하였다. 메르세데스 벤츠에서 개발된 배기량 0.8리터급 소형디젤 승용차인 Smart cat가 본 실험에 사용되어졌다. 실험용 차량은 전자식 EGR 밸브가 장착된 3기통의 터보 과급식 차량이다. 테스트벤치에서 EGR 밸브의 성능을 비교 및 분석한 후 차대동력계상에서 EGR map과 CVS-75 시험결과를 통하여 전자식 EGR 밸브의 차량적용 가능성을 여부를 수행하였다. In this study the characteristics of E-EGR valve developed by Unick were analyzed and the feasibility of application to vehicles were evaluated. Smart car (3$\ell$/100 km) and engine which is small-displacement size, 0.8-liter, of diesel passenger car developed from Mercedes-Benz were used for this experiment. It was installed a 3-cylinder turbo-charged light duty diesel engine with an electronic EGR valve. After the analysis and comparison of E-EGR valve performance under test benches, the estimation of vehicle application was executed through the EGR map and CVS-75 test result measured on the chassis dynamometer.

In vehicle exhaust systems the sound attenuation and the reduction of flow losses are often two competing demands. The present study considers a fully vehicle exhaust system and investigates experimentally both the sound attenuation and the flow performance of production configurations including the catalyst, the resonator, and the muffler. Dynamometer experiments have been conducted with 1500cc engine with speeds ranging from 1000 to 5000 rpm. Measurements include the flow rates, the temperatures and the absolute dynamic pressures of the hot exhaust gases at point locations. The present study describes the experimental aspects of an ongoing effort to validate and use the nonlinear fluid dynamic models in the time-domain for the prediction of the acoustic and power performance of firing internal combustion engines with full production exhaust systems.
