摘要
文章介绍了乘用车污染物排放模拟研究的结果。考虑到不同的平均速度和模型交通条件(城市交通拥堵、城市交通不拥堵、农村、高速公路和高速公路),使用车辆行驶测试程序确定了排放特征。这篇文章还介绍了利用蒙特卡洛方法,在单一实现车辆速度过程的基础上确定污染物排放特征以及污染物排放强度的可能性。根据污染物排放特征可以确定污染物排放强度,该强度可用于公路运输污染物排放清单(作为标准应用 COPERT 软件),并可通过污染物扩散模型用于评估环境危害程度。本文使用 HBEFA INFRAS AG 软件,根据 2020 年欧洲乘用车的代表结构,得出了与污染物排放特征相关的结果。模拟驾驶测试分别针对火花点火发动机汽车和压燃式发动机汽车进行。得出的结论是,使用专业软件模拟道路车辆的排放是确定道路运输排放特征的有效方法。
Simulation Studies of Pollutant Emission from Passenger
Cars
The article presents the results of simulation studies of pollutant emissions
from passenger cars. The characteristics of emissions were determined using the
vehicle driving test procedures, in consideration of differentiated average
velocities as well as model traffic conditions: urban traffic jam, urban traffic
with no congestion, rural, motorways, and highways. This article also presented
the possibility of determining the characteristics of pollutant emission based
on a singular realization of the vehicle velocities processes, as well as the
intensity of pollutant emission, with the use of the Monte Carlo method. The
pollutant emission characteristics enable specification of pollutant emission
intensity, which can be used for the inventory of pollutant emissions from road
transport (COPERT software applied as standard) and can be useful in the
assessment of a degree of environmental hazard by modeling pollutant dispersion.
In this article, the results related to pollutant emission characteristics were
obtained with the use of the software HBEFA INFRAS AG for the cumulative
category of passenger cars, in terms of their representative structure in Europe
in 2020. The simulation driving tests were carried out separately for cars with
spark ignition engines and for those with compression ignition engines. It was
concluded that using specialized software to simulate emissions from road
vehicles is an effective way to determine the characteristics of emissions from
road transport.
