New measuring method of smoke emission for diesel vehicle

Article Text (Baidu Translation)

摘要: 在发动机燃料与空气燃烧的化学反应及反应前后各化学元素的平衡关系的基础上, 分析了柴油机尾气排放量与燃料消耗量及排气成分中各成分排量之间的关系, 建立了道路车辆烟雾排放的测量模型和测量方法, 并在发动机试验台架及车辆路试中验证了该模型具有一定的测试精度

Abstract: Based on the chemical reaction of fuel with air in internal combustion engine and the elementary equilibrium before and after combustion, the relationship of the quantity of total exhaust gas with the fuel consumption and with the quantity of each exhaust composition was analyzed, and a new model/method was set up for measuring the smoke emission under on road conditions. The precision of the model/method was validated by an engine bench test. The smoke emission of a diesel vehicle running on road was measured using this method.
