Questions about Real Driving Emissions in Brazil

SAE Technical Paper Series, 2017
<div class="section abstract"><div class="htmlview paragraph">The motor vehicles are the main source of atmospheric pollution, especially carbon monoxide, hydrocarbons and nitrogen oxides (NOx). To reduce these emissions for environmentally acceptable levels, Europe and the United States have developed control programs, where are set ...

Predicting instantaneous engine-out NOx emissions in a real-driving vehicle data scenario

International Journal of Engine Research, 2023
As type approval driving cycles were found to be insufficient to represent the real impact of emissions from on-road vehicles, it became clear that real-driving emissions must be considered to effectively address the current transportation challenges ...

Assessing and Characterizing the Effect of Altitude on Fuel Economy, Particle Number and Gaseous Emissions Performance of Gasoline Vehicles under Real Driving

SAE technical paper series, 2023
High altitudes have a significant effect on the real driving emissions (RDE) of vehicles due to lower pressure and insufficient oxygen concentration. In addition, type approval tests for light-duty vehicles are usually conducted at altitudes below 1000 m.

Efficient Monitoring of Real Driving Emissions

2018
The diesel emissions scandal has demonstrated that real-world behavior of systems can deviate excessively from the behavior shown under certification conditions. In response to the massive revelation of fraudulent behavior programmed inside diesel cars across Europe, the European Union has defined a procedure to test for Real Driving Emissions (RDE ...

Condensation of Real-World Drive Cycle into Synthetic Drive Cycle - An Innovative Method to Predict Real Driving Emissions

SAE Technical Paper Series, 2021
<div class="section abstract"><div class="htmlview paragraph">The stringent emission regulations have put enormous pressure on auto manufacturers to develop vehicles with the required conformity factor (CF) on real driving emissions (RDE). However, evaluation of CF on multiple and varying real-world cycles by portable emission measurement ...

Real Driving Emissions from LPG Passanger Cars

2022
Passenger cars are an indispensable part of modern society, but they also have a significant impact on environment and human health. In Europe, passenger cars exhaust emissions have been regulated since 1992 with the implementation of the Euro emission standards. Since then, great improvement in exhaust emission mitigation was accomplished.

From laboratory to road – Real Driving Emissions

2016
In European emission type approval during the past years the exhaust emission limits have been reduced significantly. Although air quality was improved from 1990 on, a high percentage of the European population is exposed to air pollutant concentrations above European limit values, mainly on particles, nitrogen dioxide (NO2) and ozone (O3).

Real Driving Emissions Measurement of Brake Dust Particles

SAE Technical Paper Series, 2019
<div class="section abstract"><div class="htmlview paragraph">The measurement of brake dust particles is a complex challenge owing to its open system configuration; indeed, the emitted particles are directly spread into the environment.
