A Research on the Real Driving Emission Characteristics of Light-duty Gasoline Vehicles
The real world emissions of four light-duty gasoline vehicles meeting State-V emission regulation are measured with portable emission measurement system in accordance with the real driving emissions ( RDE) pro-cedure newly formulated by EU. The results show that the conformity factor of CO is higher than that of NOx . The in-stantaneous emission rates of CO and NOx increase with the rise in acceleration. Under high speed condition, the in-stantaneous emission rate of pollutants reaches the peak value when vehicle acceleration exceeds the maximum accel-eration of NEDC cycle, and the effects of these peaks of CO instantaneous emission rates on the conformity factor of CO for total cycle can't be ignored, so it is necessary to pay more attention to the CO emission of gasoline vehicle in formulating RDE regulation.
