The key elementary reactions, key intermediate species and key radicals were analyzed. The results indicated that n-heptane showed the two-stage auto-ignition, and heat release with low temperature reaction(LTR) and high temperature reaction(HTR), and heat release with HTR is consist of blue-flame reaction and hot flame reaction.

The auto-ignition and combustion mechanisms of n-heptane were investigated by using a zero-dimensional thermodynamic model coupled with a detailed kinetic model. The key elementary reactions, key intermediate species and key radicals were analyzed. The results indicated that n-heptane showed the two-stage auto-ignition, and heat release with low temperature reaction(LTR) and high temperature reaction(HTR), and heat release with HTR is consist of blue-flame reaction and hot flame reaction. At the low temperature, H-atom abstraction from n-heptane occurs primarily by OH and HO_2, then the first O_2 addition and isomerization. The second O_2 addition is the most important elementary reaction for the low temperature branching, and the successive decomposition of its production is the main source of OH radical at LTR. Blue-flame reaction is controlled by H_2O_2 decomposition, which is the main source of OH at HTR. In this stage, OH abstracts H-atom from CH_2O to generate HCO, and then HCO oxidation to CO. Hot-flame reaction is dominated by the oxidization of CO to CO_2. OH radical is the most important radical in the oxidation of CO and H-abstraction from n-heptane.

This paper discusses the chemical reaction kinetics processes in a homogenous charge compression ignition (HCCI) engine fueled with dimethyl ether / compress natural gas using a zero-dimensional detailed kinetic model. The calculated results agreed well with the experimental results and indicated that the combustion process experienced two stages: low-temperature reactions and high-temperature reactions. DME was oxidized first because of its low ignition temperature, and CNG was burned during the high-temperature reaction stage for its abundant radicals and high temperature produced by DME combustion. Increasing initial temperatures resulted in a higher heat release rate and shorter combustion duration. The DME concentration and the CNG concentration affected the two combustion stages separately. As the CO_2 concentration was increased, the combustion rate was slowed down and ignition was delayed. The HCCI operating range could be expanded if the concentration of DME, CNG and CO_2 would be adjusted correctly.

The auto-ignition and combustion mechanisms of dimethyl ether (DME) in a four-stroke HCCI engine were investigated by using a zero-dimensional thermodynamic model coupled with a detailed chemical kinetics model. The results indicated that DME indicates two-stage combustion, heat release with low temperature reaction (LTR) and high temperature reaction (HTR), and heat release with HTR can be separated into two stages: blue flame and hot flame. HCCI ignition is controlled by hydrogen peroxide (H_(2)O_(2)) decomposition. Formaldehyde (CH_(2)O) is the main source of H_(2)O_(2) and CH_(2)O is formed by reaction 332. Based on the sensitivity analysis of chemical reactions, the major paths of the DME reaction occurring in the engine cylinder are clarified. The major paths of the DME reaction is abstract H from DME, followed by first addition O_(2 )and second addition O_(2), then oxidation to formaldehyde (CH_(2)O), the formyl radical (HCO), and finally CO. OH plays a very important role in DME oxidation and it is the essential radical in the H-atom abstraction from DME and CO oxidation. CO oxidation occurs at hot flame by the reaction: CO+OH=CO_(2)+H.

应用零维详细化学反应动力学模型对二甲基醚均质压燃燃烧反应机理进行了数值模拟研究。结果表明二甲基醚放热反应为典型的双阶段放热反应,经历低温反应、负温度系数区域和高温反应三个过程,高温反应又分为蓝焰和热焰两个阶段。二甲基醚自燃着火由过氧化氢(H2O2)分解所控制,甲醛(CH2O)是过氧化氢的主要来源。基于化学敏感性分析,得到了均质压燃二甲基醚反应的主要途径:首先是二甲基醚脱氢,经过两次加氧后得到甲醛基;然后生成甲酸基(HCO);最后生成一氧化碳(CO)。在二甲基醚的氧化反应过程中,氢氧根(OH)发挥着重要的作用,它是二甲基醚脱氢反应和CO氧化过程中的主要自由基。
