In order to examine fundamental features of autoignition of n-butane/air mixtures and HCCI combustion initiated by PFJ, combustion tests were carried out using the compact Rapid Compression Machine. These led to the following conclusions.(1)In HCCI combustion, autoignition did not occur everywhere in the combustion chamber at the same time due to the existence of non-unified temperature distribution in the chamber during compression, however, the combustion started across a wide area in the chamber, which was followed by the full-scale combustion.(2)The jet began to issue from the orifice of the PFJ igniter within one millisecond from the beginning of the spark discharge in the cavity, and the intensity of the jet image once became weak, and then the combustion occurred across a wide area in the combustion chamber, which was similar to the autoignition case.(3)The light emission characteristics of combustion initiated by PFJ were similar to those of autoignition case, especially the behavior of "Blue light". Thus the flame did not propagate continuously from the jet, but the jet issuing from the PFJ igniter behaved as a trigger for the autoignition of the fuel in the combustion chamber.

为了研究正丁烷/空气混合气自燃和PFJ引发的HCCI燃烧的基本特性，使用紧凑型快速压缩机进行了燃烧试验。由此得出以下结论。(1)In在HCCI燃烧中，由于压缩过程中燃烧室内存在不均匀的温度分布，自燃现象不会在燃烧室内的任何地方同时发生，而是在燃烧室内的一个大范围内开始燃烧，然后进行全面燃烧。（2）在空腔内火花放电开始后的1毫秒内，射流开始从PFJ点火器的喷口喷出，射流图像的强度一度变弱，然后在燃烧室中的大范围内发生燃烧，这与自燃情况相似。（3）PFJ引发燃烧的发光特性与自燃情况相似，尤其是“蓝光”现象。因此，火焰并没有从射流连续传播，但从PFJ点火器发出的射流表现为燃烧室中燃料自燃的触发器。
