Developing the emission inventory for mobile sources is the initiating step of motor vehicle emission control. This paper investigates vehicle activity data in Macao including vehicle population, vehicle types, vehicle registration distribution, and annual mileage accumulations. MOBILE5 and PART5 models were modified and used to calculate the emission coefficients of gaseous and particulate air pollutants from onroad motor vehicles. The total exhaust CO, NOx, HC, PM10 and PM2.5 from vehicles were 15 852 t, 2 416 t, 2 449 t, 141 t, and 128 t in Macao in 1999. The different vehicle contributions to the total vehicular emissions were estimated. The results show that motorcycles and gasoline passenger cars are the most important contributors to CO and HC.

建立机动车排放清单是实行机动车污染控制的基础。通过对澳门机动车保有量及其构成、车辆登记分布和累积里程分布的调查分析,获得了澳门机动车基本的运营特征参数。采用修正的MOBILE5模式和PART5模式,计算了澳门机动车排放的气态污染物和颗粒污染物的排放系数,并确定了澳门机动车污染物的排放总量和分车型的排放分担率。1999年澳门机动车CO,NOx,HC,PM10和PM2.5的总排放量分别为15852t,2416t,2449t,141t和128t。研究结果表明,控制摩托车和汽油轿车可以有效削减HC和CO的排放;而对于NOx和颗粒物,公共汽车和重型柴油车应是主要的控制车型。

It's a basic work to study the characteristics of vehicular emissions and give emission factors for development of vehicular emission inventory and decision-making of the control strategies. On-board emission measurements of on-road vehicles are regarded as important complementary to emission laboratory dynamometer tests. On-board exhaust emission measurements were conducted on seven samples of gasoline cars in a typical road in Macao, using AVL DiGas 4000 light five-gas analyzer. It was found that there was...

It's a basic work to study the characteristics of vehicular emissions and give emission factors for development of vehicular emission inventory and decision-making of the control strategies. On-board emission measurements of on-road vehicles are regarded as important complementary to emission laboratory dynamometer tests. On-board exhaust emission measurements were conducted on seven samples of gasoline cars in a typical road in Macao, using AVL DiGas 4000 light five-gas analyzer. It was found that there was an obvious reduction of gaseous pollutant emissions from cars equipped with electronic fuel injection and three-way catalytic converter system (referred to as EFI cars in the following), compared to old carburetor cars. The average volume concentrations of CO, HC and NO of carburetor cars were 227×10 -6,1.57% and 1477×10 -6, respectively, while those of EFI cars were 33×10 -6,0.21% and 131×10 -6, which were about 1/11 through 1/7 of the former. However, there were high emissions during the cold start of EFI cars. The arithmetical mean concentrations of CO and NO emissions of EFI cars were calculated and their absolute values were predominantly contributed by high concentrations with low frequency. Furthermore, the emission factors of gasoline cars were estimated by test data, and at the same time, MOBILE5 model was used to calculate average emission factors of gasoline cars in Macao in 2000. The ratios between the results calculated by model and estimated by experiment data were in the range of 59%~139%, which would narrow into 68%~132% if only annual average emission factors were compared. The results suggest that EFI+TWC systems equipped in vehicles have good effect on the emission reduction, but catalytic converters are not activated during the cold start. Technical improvement of EFI cars, which could reduce the occurrence of high emissions with low frequency during the operation, would decrease their average level on exhaust emissions a lot. Furthermore, it's reliable that the emission factors of gasoline cars in Macao calculated by modified MOBILE5 model.
