直馏石脑油在新提出的燃烧概念（称为多重预混压缩点火（MPCI）模式）中在单缸柴油发动机上以不同速度进行测试。还对部分预混压缩点火（PPCI）模式进行了研究以进行比较。作者提出的MPCI模式是通过压缩上止点（TDC）周围“喷雾-燃烧-喷雾-燃烧”顺序的多个预混燃烧过程来实现的。喷雾与燃烧事件优选完全分开，以“喷射结束后燃烧，燃烧结束后喷射”为主导特点，保证多级预混压缩点火。 PPCI 模式被称为“喷雾-喷雾-燃烧”顺序，燃烧开始 (SOC) 与喷射结束 (EOI) 分开。直馏石脑油的研究辛烷值（RON）为58.8，试验发动机的压缩比和排量分别为16.7和0.5L。采用双注入策略生成 PPCI 和 MPCI 模式。 MPCI模式的最大压力上升率和NOx排放均低于PPCI模式，并且在较低的发动机转速下更容易产生MPCI模式。柴油也与PPCI模式一样在双喷射策略下进行测试，但燃油效率和排放性能比直馏石脑油差。
Straight-run naphtha is tested in the newly raised combustion concept, called multiple premixed compression ignition (MPCI) mode, on a single cylinder diesel engine under different speeds. The partially premixed compression ignition (PPCI) mode is also investigated for comparison. The MPCI mode proposed by the authors was realized by multiple premixed combustion processes in a sequence of “spray–combustion–spray–combustion” around the compression top dead center (TDC). The spray and combustion events are preferred to be separated completely, with a dominant feature of “Combust After Injection End, Inject After Combustion End” to ensure the multiple-stage premixed compression ignition. The PPCI mode is well known as the “spray–spray–combustion” sequence with the start of combustion (SOC) separated from the end of injection (EOI). The straight-run naphtha has a research octane number (RON) of 58.8, and the compression ratio and displacement of the test engine is 16.7 and 0.5L. Double injection strategy is employed to generate the PPCI and MPCI modes. Maximum pressure rise rate and NOx emission of the MPCI mode is lower than that of PPCI mode, and it is easier to produce MPCI mode at lower engine speed. Diesel is also tested under double injection strategy just as the PPCI mode, but the fuel efficiency and emission performance is worse than that of straight-run naphtha.
