【正文】 effects of the pression ratio, the fuelair equivalence ratio, the intake charge heating, the engine speed, EGR and fuel additive on the HCCI ignition and bustion are studied. The results show that the HCCI bustion fueled with DME consists of a low temperature reaction heat release period and a high temperature reaction heat release period. It is also founded that increasing the pression ration, the equivalence ratio, the intake charge temperature and the content of H2O2, H2 or CO cause advanced ignition timing. Increasing the engine speed, adoption of cold EGR and the content of CH4 or CH3OH will delay the ignition timing.Key words: HCCI, chemical kinetics, numerical simulation, DME, EGR, fuel additive小四號(hào)Times New Roman加黑,key words之間加一空格 。第一章 緒論正文: 中文為五號(hào)宋體，英文為五號(hào)Times New Roman，首行縮進(jìn)二個(gè)字。為滿足嚴(yán)格的排放要求，研究人員在各個(gè)相關(guān)領(lǐng)域進(jìn)行了大量的研究工作，改進(jìn)發(fā)動(dòng)機(jī)的燃燒系統(tǒng)作為一個(gè)重要解決途徑，也取得了一定進(jìn)展。汽油機(jī)和柴油機(jī)的燃燒方式都不能解決碳煙和氮氧化物生成的tradeoff關(guān)系,因而很難在這兩種燃燒模式下通過(guò)改進(jìn)燃燒來(lái)同時(shí)大量降低碳煙和氮氧化物的生成。目前HCCI數(shù)值模擬研究主要集中在單區(qū)、多區(qū)和多維模型上[2]。每一章需另起一頁(yè)。公式可按章節(jié)順序編號(hào)或按全文統(tǒng)一編號(hào)。等數(shù)學(xué)符號(hào)處轉(zhuǎn)行。表1 選取組分的熱力學(xué)性質(zhì)組分Hf(kcal/mol)Sf(kcal/mol)Cp(kcal/mol)A1A2A3100100100 續(xù)表1組分Hf(kcal/mol)Sf(kcal/mol)Cp(kcal/mol)A4A5A6A7A8100100100表題允許下頁(yè)接寫(xiě)，接寫(xiě)時(shí)表題省略，表頭應(yīng)重復(fù)書(shū)寫(xiě)，并在右上方寫(xiě)“續(xù)表xx”。第五章 結(jié)論 正文內(nèi)容中文五號(hào)宋體，英文用五號(hào)Times New Roman，首行縮進(jìn)二
