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.
