Emissions Analysis

Emissions that result in pollution from engines are strictly regulated. The next generation of heavy-duty diesel engines will be the cleanest by far. Some advanced fuels can reduce these emission levels even further.

In order to accurately measure emissions at these very low levels, the ReFUEL Lab features advanced emission measurement systems, and supplements these systems with air and fuel conditioning that ensures excellent repeatability.

Emission Measurement Capabilities

• Compliant with 2007 Code of Federal Regulations (40 CFR Part 86 Subpart N)
• Continuous measurement of emissions: NO_x, HC, CO, CO₂
• Particulate Matter (PM) measurement
  • 2007-compliant filter media and holders
  • Ultra-micro balance: 0.1 µg readability
  • Class 1000 clean room/environmental chamber
  • Active vibration and static mitigation
• Additional, unregulated emissions measurements:
  • Carbonyls, Aldehydes, and Ketones
  • Hydrocarbon Speciation (C1–C12)
