摘要

在一台2105柴油机上进行了部分预混充量压缩着火和直接喷射(PCCI-DI)复合燃烧对发动机有效热效率和排放等性能影响的研究.试验包括:在进气道预先对二甲醚燃料和空气进行混合

再将形成的均质混合气送入燃烧室; 在压缩行程末期

利用压燃式发动机的燃油喷射装置将柴油喷入燃烧室

从而实现了PCCI-DI燃烧.试验结果表明

与传统直喷压缩燃烧方式相比

在中低转速和低负荷工况下

采用PCCI-DI燃烧模式的发动机能降低NO

和碳烟的排放量

提高有效热效率

但HC和CO排放量显著增加; 随着二甲醚预混比的增加

排放量略有所降

碳烟排放量可进一步降低.

Abstract

The study on the influence of partial premixed charge compression ignition-direct injection(PCCI-DI)compound combustion on engine performance such as brake thermal efficiency and emission was experimentally conducted in a 2105 engine. In the experiment

PCCI-DI combustion was realized by the way that the partial homogeneous mixture composed of the pilot DME and air entered a combustion chamber through the intake pipe and diesel fuel was directly injected into the combustion chamber with the fuel injection equipment of the compression ignition engine at the terminal stage of a compression stroke. Experimental results show that

compared with the conventional compression ignition combustion

both NO

and smoke emission decreased and the brake thermal efficiency rised

however

HC and CO emissions were significantly higher with PCCI-DI combustion at low a

nd medium speed and load. In addition

emission decreased slightly and smoke emission decreased by 30%-40% with an increase in DME premixed ratio.
