Characteristics of atmospheric ammonia and its relationship with vehicle emissions in a megacity in China

Atmospheric Environment, 2018
Atmospheric ammonia plays an important role in haze formation in East China. In this study, long-term measurements of NH3 concentrations were implemented at urban, suburban, and tunnel sites in Shanghai, the largest city in East China.

Low Emission Vehicle Technology for Ultra Low Emissions Vehicle and European Stage 3 Emissions Standards

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 1995
Technology to meet the California Air Resources Board's (CARB) ultra low emissions vehicle (ULEV) legislation is being developed by most major vehicle manufacturers. To achieve the required reduction in cold start emissions, mainly HC and CO, compared to current three-way catalyst (TWC) technology, very early catalyst light-off has to be achieved ...

Monitoring and Control of Vehicles’ Carbon Emissions

2018
Machine-to-machine communication, known as Internet of Things (IoT), allows machines to connect using variety of sensors and devices. Thus, feedbacks to govern energy, agriculture, transportation and environment are able to be obtained. The IoT provides opportunity not only for creation of new businesses and investments, but for reduction of carbon ...

Influence of translational vehicle dynamics on heavy vehicle noise emission

Science of The Total Environment, 2019
Vehicle dynamics can play a significant role in the noise emission from heavy vehicles. In this work, a heavy vehicle noise emission model is presented to study the influence of translational vehicle dynamics on the sound power level emitted by heavy-duty trucks.

Real-World Vehicle Emissions: A Summary of the Seventeenth Coordinating Research Council On Road Vehicle Emissions Workshop

Journal of the Air & Waste Management Association, 2007
The Coordinating Research Council held its 16th workshop in March 2006, with 83 presentations describing the most recent mobile source-related emissions research. In this paper, we summarize the presentations from researchers who are engaged in improving our understanding of the contribution of mobile sources to air quality.

Empirical model of vehicle emissions

Environmental Science & Technology, 1993
An empirical model that characterizes the relationship between equilibrium vehicle emission distributions and malfunction, repair, and replacement rates by splitting vehicles into two emission categories has been developed. Gross emitters and clean vehicles are defined by the magnitude of their emissions compared to an arbitrarily chosen cut point. The

More Roundabouts and Reduced Vehicle Emissions?

Environmental Science & Technology, 2012
As a native Californian with approximately 10 years of European living and driving experience, I write on that personal favorite of British inventionsthe roundaboutand what it might do for reduced vehicle emissions (e.g., CO2 and other greenhouse gases).
