In order to clarify the reason why NOx emissions factor becomes higher at vehicle acceleration at intersections etc, two freight vehicles, that have EGR system for the reduction of NOx, were tested by an on-board NOx measurement system. Higher NOx emissions factor was observed in operations in lower-gear operation for each vehicle. Since the engine speed change was higher in the operation of lower gears, NOx emissions characteristics were analyzed in view of engine torque, NOx mass emissions and EGR rate, considering engine speed change. It was found that lower-gear operations made the engine speed change higher and the EGR rate lower. This seems to be one of the factors to engender the intensive NOx pollution at roadsides.
