This paper use the AVLCompanys emissions sampling and analysis equipment to take the vehicle emission test with a heavy-duty gasoline vehicle on one chassis dynamometer.And then have an analysis and compare on the PN value and the value of pollu-ted gas(CO,THC,and NOx)during different start test cycles.This study show that the cold starting condition has higher particulate number and more gaseous pollutants than hot starting condition,the particulate number was concentrated in different drive conditions during different starting conditions,and it is close to the sudden acceleration.
