轻型国五柴油车排放油耗数据研究分析

Research and Analysis of Emission Fuel Consumption Data of Light Country Five Diesel Vehicles

分别选取不同年代版型的4款同一型号的轻型柴油车进行常温下冷起动后排气污染物排放试验(Ⅰ型试验),根据不同排放后处理配置进行排放油耗数据研究分析。选取2012年美规版柴油车进行常温下冷起动后排气污染物排放试验(Ⅰ型试验),采用柴油排放分析系统MEXA-7000HLE进行试验,柴油排放分析系统又分为STD和LE两个通道,对排放油耗数据研究分析。

Four types of diesel vehicles were selected to conduct Type I test,according to the different exhaust aftertreatment devices,the research and analysis of the exhaust emissions and fuel consumption data are conducted.The 2012 American version of the diesel vehicle was selected for the exhaust emission test after cold start at room temperature(Type I test).The diesel emission analysis system MEXA-7000HLE was used for the test.The diesel emission analysis system is further divided into two channels,STD and LE,to study emissions fuel consumption data.
