Celem tego opracowania jest wyjaśnienie charakterystycznych cech zapłonu, procesu spalania, granicy spalania stukowego i granicy wypadania zapłonu mieszanki gazu ziemnego i niewielkiej ilości eteru dimetylowego (DME) w silniku HCCI. W badaniu spalania gaz ziemny i niewielka ilość DME zostały dodane do powietrza dolotowego w postaci mieszanki jednorodnej. Współczynnik nadmiaru powietrza dla gazu ziemnego został zwiększony w celu wykrycia granicy spalania stukowego lub granicy wypadania zapłonu silnika testowego HCCI przy stałej ilości DME. Eksperymentalnie zbadano wpływ dodania gazu ziemnego na stłumienie niskotemperaturowych reakcji DME oraz wpływ ilości DME i temperatury dolotu na szybkość reakcji utleniania, granicy spalania stukowego mieszanki DME/gaz ziemny, oraz zakres obciążenia silnika HCCI.

The objectives of the present study is to clarify ignition characteristics, the combustion process, the knock limit and the misfire limit of natural gas mixed with a small amount of dimethyl ether (DME) in a HCCI engine. In the combustion test, natural gas and a small amount of DME were charged into the suction air homogeneously. The equivalence ratio of natural gas was increased to find the knock limit or the misfire limit of the HCCI test engine under a constant DME amount. The effect of the natural gas addition on suppression of the low temperature reaction of DME, and the effects of the DME amount and the intake temperature on the reaction rates, the knock limit of the DME/natural gas mixture, and the operation load range of the HCCI engine were investigated experimentally.

Background: Anatomical knowledge of the duodenojejunal flexure is necessary for abdominal surgeries, and also important for physiologic studies about the duodenum. But little is known about the anatomy of this region in mammals. Here, we examined comparative anatomy to understand the anatomical formation of the duodenojejunal flexure in mammals. Materials and methods: The areas around the duonenojejunal flexure were observed in mouse, rat, dog, pig, and human, and the anatomical structures around the duodenojejunal junction in the animals were compared with those in human. Results: The superior and inferior duodenal folds, and the superior and inferior duodenal fossae were identified in all examined humans. In pig, the structures were not clearly identified because the duodenum strongly adhered to the retroperitoneum and to the mesocolon. In mouse, rat, and dog, only the plica duodenocolica, which is regarded as the animal counterpart of the superior duodenal fold in human, was identified, and other folds or fossae were not observed, probably because the duodenum was not fixed to the parietal peritoneum in those animals. Transection of the plica duodenocolica could return the normally rotated intestine back to the state of non-rotation in rat. Conclusions: This study showed the anatomical similarities and dissimilarities of the duodenojejunal flexure among the mammals. Anatomical knowledge of the area is useful for duodenal and pancreatic surgeries, and for animal studies about the duodenum. (Folia Morphol 2018; 77, 2: 286–292)
