The advantages of hcci are numerous comparing with the traditional engine. relative to si gasoline engines, hcci engines are more efficient, because they have no elimination of throttling losses, use the high compression ratios and have shorter combustion duration. relative to cidi engines, hcci engines have extraordinarily lower emissions of pm and nox and can offer more power as high as cidi engines with the dilute homogeneous air and fuel mixture
與傳統的發動機相比均質壓燃（ hcci ）具有很多優勢:與火花點火汽油機相比， hcci發動機由於沒有節流損失，壓縮比較高，燃燒持續期短，其效率更高;與直噴柴油機相比， hcci發動機的碳煙和氮氧化物排放非常低，並且稀薄空燃混合氣可以產生與柴油機一樣高的功率。Quality problem is a significant strategy problem. quality management in work site is the important link of the overall quality managment. the paper summarizes the missions of quality management in situ in four aspects, i. e. the prevention of quality defects, control of quality working procedure. improvement of quality, inspection and evaluation of quality. the specific requirements and implement measures for quality management which should be performed strictly by managing staff, technicians and workers are also proposed in this paper
乙醇，俗稱酒精.乙醇汽油是一種由糧食及各種植物纖維加工而成的燃料乙醇和普通汽油按一定比例混配的替代能源.按照現行國家標準，乙醇汽油是用90 ?的普通汽油與10 ?的燃料乙醇調合而成，它可有效地改善油品的性能和質量，降低一氧化碳、碳氫化合物、氮氧化物等主要污染物的排放，有著巨大的環保效應，而且它對機動車的行駛性能也沒有影響The dry atmosphere consists almost entirely of nitrogen ( 78. 1 % volume mixing ratio ) and oxygen ( 20. 9 % volume mixing ratio ), together with a number of trace gases, such as argon ( 0. 93 % volume mixing ratio ), helium, and radiatively active greenhouse gases such as carbon dioxide ( 0. 035 % volume mixing ratio ), and ozone
干大氣幾乎完全由氮（ 78 . 1 %的體積混合比）和氧（ 20 . 9 %的體積混合比）構成，還包括一些微量氣體，如氬（ 0 . 93 %的體積混合比） 、氦，以及對輻射起作用的溫室氣體如二氧化碳（ 0 . 035 %的體積混合比）和臭氧。
