Brake Emissions Overview
Brake Emissions are the direct release of particulate matter, and gases from a vehicle friction event. Reducing brake emissions is an integral part of achieving the UN Sustainable Development Goal 11 for Sustainable Cities and Communities.
Measuring the brake emissions under known conditions in a laboratory-like LINK, which is meeting industry standards and replicating the vehicle behavior, is an integral part of developing cleaner and better braking systems. Part of the work to achieve Goal 11 is the combination of newer friction coupled with electric powertrains and the brake emissions laboratory testing that helps the engineer move in that direction.
Model 6330 Brake Emissions Testing
The M6330 is an enclosed, dynamometer-based brake sampling system that lets you replicate a duty cycle from your vehicle and collect samples of particulate matter under tightly-controlled conditions such as air temperature, humidity, brake cooling, and many more. You can then measure a large variety of characteristics like particulate mass, particulate number, particle size distribution, and concentration—as well as sample for chemical and toxicology assessments-all in a single setup.
No other laboratory in the world can do this, and no other lab meets CARB, EPA, and ISO standards all at once.
Our unique measurement methodology and design overcome the inherent limitations of other systems, yielding representative, isokinetic samples over the entire range of significant particles. The bottom line is a more efficient process and more accurate results—actionable conclusions you can trust.
The M6330 is available for purchase as a system, or we can perform your testing as a service. Our modular system design allows different levels of instrumentation, from core instruments for PM2.5, PM10, and PN to diluters, catalytic strippers, real-time mass measurement, etc. When we perform testing as a service, we provide you with all of this data, including weight (with 0.000001 g resolution).
The M6330 system is controlled by our industry-leading ProLINK suite of software tools, which lets you analyze your data and create virtually unlimited custom reports through simple menu selections. Using a Binary Large Object (BLOB), 100+ serial channels of particle count, concentration, and size distribution data are automatically collected in real-time into a single ProLINK file, eliminating synchronization problems, and time-consuming post-processing. Test reports can be viewed in normal Pro-LINK report format or as VDA 305 EEC/EED and DSA files.
