Spray and combustion characteristics of Splitting High-Pressure Injection (SHPI) was experimentally investigated. SHPI is the split injection in which the period from the start of the first injection to the end of the second injection and the total injection amount are adjusted to the same as the single stage injection. Diesel fuel was used as a test fuel.As the interval (no injection period) between the 1st and 2nd injections is increased, an increase in the spray tip penetration due to the higher injection pressure of SHPI can be avoided. The spray angle and the mass of ambient gas entrained are incrased, that indicates that the mixing of the fuel and ambient gas is enhanced. The integrated KL factor (total soot amount) in the flame and the mean flame temperature are both decreased. It is demonstrated the pissibility of the simultaneous reduction of soot and NOx by Splitting High-Pressure Injection (SHPI).

对分离式高压喷射(SHPI)的喷雾和燃烧特性进行了实验研究。SHPI是将从第一次注射开始到第二次注射结束的时间和总注射量调整为与单级注射相同的分步注射。以柴油为试验燃料，通过增加第一次和第二次喷油的间隔时间(不喷油周期)，可以避免由于SHPI喷油压力较高而导致喷嘴穿透能力的增加。喷雾角度和携带的环境气体质量增大，表明燃料与环境气体的混合增强。火焰中的积分KL因子(总碳量)和平均火焰温度都降低了。论证了裂解高压喷射(SHPI)同时还原碳烟和NOx的可行性。
