Research on Influence of Beijing-VI Diesel on Consumption and Emission Characteristics of Euro VI Diesel Bus

The characteristics of fuel consumption and emission from a euro VI diesel bus burning Beijing-VI diesel and China-V diesel were tested on heavy chassis dynamometer under C-WTVC testing cycle. The results indicated that the fuel consumption of Beijing-VI diesel is 1.12L/100km lower than China-V diesel and has the advantage of saving energy. A major emission factors were decreased, NOx emission reduced by 18%, PM emission reduced by 20%, CO and HC slightly decreased under C-WTVC testing cycle. Under city conditions, road condition and highway conditions, the NOx emission reduced by 25%, 18%, 16%.
