Portable emissions measurement system (PEMS) testing services – demonstrate compliance with emission and fuel consumption standards.

Highway in the dark

PEMS testing ensures that your light or heavy-duty vehicle, off-road equipment or machinery stays within appropriate legal limits for emission and fuel consumption. We offer PEMS testing to ensure that you comply with transportation industry standards, including those set forth by the US, the EU and other government entities.

  • Evaporative emissions testing
  • Mileage accumulation
  • Data analytics
  • Homologation
  • Engineering services

Emissions Analytics Support

Extracting full value from in-use test data can be difficult due to the complexity of the control system and the massive amount of information that is logged at a high frequency. Interpreting data obtained outside the dynamometer laboratory is particularly challenging, as weather, drive route, road grade, traffic and driver tendencies can all have a significant impact on emissions, and in-use tests are not reproducible. Prototype and production launch vehicles can use our PEMS technology to gain real world information that supports the vehicle development process.

PEMS Data Analysis

We offer data analytics solutions ranging from ad hoc data exploration to big data computing. Our data analytics software and services will help you to uncover hidden relationships between emissions, fuel consumption and control system behavior.

Test data is segregated into different modes of operation to provide statistics-based visualizations for individual tests or entire campaigns. Preconfigured dashboards allow visualization of test data by subsystem and by event, facilitating deeper data exploration. Clustering and association algorithms can be used to explore low temperature operation, emissions implications and engine and catalyst control tradeoffs, as well as to provide causation analysis for malfunctions and anomalies. Machine learning allows you to isolate control system differences in situations where good and poor performance have been observed.
