摘要

在单火花塞均质预混燃烧室结构的基础上增设双火花塞点火系统

通过改造电控燃油喷射系统实现了双火花塞轻度均质稀燃模式的稳定运行。通过设置双火花塞化学当量比(过量空气系数λ为1)、双火花塞轻度均质稀燃(λ为1.1)和单火花塞化学当量比(λ为1)的状态

测试了双火花塞对轻度均质稀燃过程及其燃烧特性的影响。研究表明:双火花塞在加速缸内稀燃的总体效应主要体现在10%～50%累积燃烧放热的前期燃烧期; 轻度均质稀燃(λ为1.1)状态的双火花塞燃烧放热和循环变动特性仍明显优于单火花塞化学当量比状态; 在低负荷非稳定燃烧工况

双火花塞在加速缸内燃烧过程、减小循环变动率和提高燃烧稳定性的效果上更加突出。台架测试表明:在稀燃运行区域

双火花塞轻度均质稀燃模式的燃油经济性较单火花塞化学当量比燃烧模式提升了3%～6%

并有助于降低有害物的排放。

Abstract

A dual-spark plug ignition system is assembled on a gasoline engine ignited by single-spark plug with homogeneous premixed combustion. By reconstructing electronic control fuel injection system

it is observed that the engine can be steadily operated in a mild homogeneous lean burn mode. To further investigate the effect of double-spark plug ignition on mild homogeneous lean combustion

three running states

dual-park plug with chemical equivalent ratio(λ=1)

dual-spark plug with lean mixture(λ=1.1)and single-park plug with equivalent ratio(λ=1)

are tested for character diagnosis of the combustion. The overall effect of in-cylinder combustion acceleration due to the double-spark plug ignition is mainly reflected in the early combustion stage of 10%-50% mass fraction burned; and the heat release together with the cyclic variation of the double-spark plug with lean mixture is superior to the single-spark plug with stoichiometric mixture obviously. And the effect of combustion process accelerating in the cylinder

cyclic variation rate reducing as well as the combustion stability improving are much more outstanding for the double-spark plug ignition

especially under the unstable combustion condition with lower load. Bench test also shows that the dual-spark plug lean burn mode enables to improve fuel economy by 3%-6% compared with single-spark plug stoichiometric mode in the lean burn operation area

and to reduce emission of deleterious substances.
