本文在单缸发动机中研究了 HCCI 和 PCCI 等先进燃烧概念。实验中PCCI是通过DME的部分抽吸和部分直喷相结合的方式实现的,这是获得HCCI的折衷方案,即仅预混合一部分燃料,部分燃烧仍由喷射正时控制。对 DME 发动机中的 PCCI 和 HCCI 燃烧进行了基础研究。还进行了DICI手术进行比较。结果表明,对于PCCI燃烧工况,pmax、(dp/dθ)max和放热率介于HCCI和DICI工况之间,并且随着预混比的增加而增大。 PCCI燃烧的燃烧持续时间比HCCI燃烧的燃烧持续时间长,但比DICI燃烧的燃烧持续时间短。此外,随着预混合比的增加,燃烧持续时间减少,制动热效率增加。 PCCI 燃烧操作的 CO 和 HC 排放量低于 HCCI 发动机。与传统的 DICI 运行相比,PCCI 燃烧运行的 NOx 排放量显着降低。实验还表明,喷油正时对PCCI燃烧模式下DME发动机的性能和排放有很大影响。
In this paper advanced combustion concepts such as HCCI and PCCI were studied in a single-cylinder engine. PCCI was achieved by the combination of part aspiration and part direct injection of DME in the experiments, which was a compromise to obtain HCCI in that only a portion of the fuel was premixed and the portion of combustion was still controlled by the injection timing. Basic investigations toward the PCCI and HCCI combustion in a DME engine were carried out. DICI operation was also conducted to make a comparison. Results showed that as for the PCCI combustion operation, pmax, (dp/dθ)maxand heat release rate were between the values of HCCI and DICI operation and they increased with a rise of premixed ratio. The combustion duration for the PCCI combustion was longer than those of HCCI combustion, but was shorter than that of DICI combustion. Furthermore, the combustion duration decreased and the brake thermal efficiency increased with an increase in premixed ratio. CO and HC emissions for the PCCI combustion operation were lower than those of the HCCI engine. In comparison to conventional DICI operation, NOxemissions for the PCCI combustion operation decreased significantly. Experiments also indicated that the fuel injection timing had a great influence on the performance and emissions of a DME engine at a PCCI combustion mode.
