| Popis: | 106 Normally, the vehicle emissions tests were conducted in laboratory equipped with chassis dynamometer, constant volume sampler system and emission analyzers in order to measure pollutants (weighted in gram) per kilometer under specific driving conditions. However, this testing method is unable to simulate all on-road parameters such as traffic, climate change, etc. With development of technology, overall performance of emission analyzers have greatly improved. For example, it not only takes short time to measure concentration of vehicle emissions, but they are also small enough to be placed in a car, which makes it easy to measure real-time vehicle emissions. This kind of device is called Portable Emission Measurement systems (PEMS). The objective of this research is not only to introduce the method of on-road Real Driving Emissions (RDE) for light-duty vehicle, initial conditions, execution procedures, analysis method, etc. by using PEMS equipment, but is also to undertake quantitative measurement and analysis with three Diesel passenger vehicles. Hopefully, this introduction could help more people understand the new testing method. |
