摘要

为了定量阐明采用停缸(CDA)技术改善发动机部分负荷工况燃油经济性的机理

通过台架试验对CDA发动机在停缸和全缸模式下的燃烧与排放及燃油经济性进行了研究

并结合数值模拟方法对CDA发动机的能量平衡进行了定量分析

以确定各因素对节油的影响。结果表明:与全缸模式相比

在停缸模式下工作缸滞燃期和燃烧持续期缩短

最高缸内压力和最大瞬时放热率增加

燃烧循环变动降低; HC和CO排放降低

但NO

排放增加。在试验工况下

CDA发动机节油率为8.2%～15.8%

其中缸内传热损失和泵气损失减少

两者节油贡献率分别为80%～111.9%和30.3%～37.4%

而摩擦损失和排气能量增加

两者节油贡献率分别为-9.2%～-20.3%和-1.2%～-26.5%。因此

缸内传热损失减少是CDA发动机最主要的节油因素。

Abstract

To quantitatively expound the mechanism of using cylinder deactivation(CDA)technology to improve the partial-load fuel economy of a direct-injection spark-ignition engine

bench test was carried out to investigate the combustion and emission characteristics and fuel economy of the engine in the CDA and full-cylinder modes. Moreover

numerical simulation was used to quantitatively analy-e the energy balance and determine the effects of various factors on fuel saving of the CDA engine. The results show that

in comparison with the full-cylinder mode

the ignition delay and combustion duration are shortened

the peak values of the in-cylinder pressure and heat release rate are increase

and the cyclic variation of combustion is reduced in the CDA mode. In addition

HC and CO emissions are reduced

while NO

emissions are increased in the CDA mode. Under the test conditions

the fuel economy of the CDA engine is improved by 8.2% to 15.8%. In comparison with the full-cylinder mo
