Exhaust Aftertreatment Testing Software and Systems - Production Testing Software

Starting in 1997, engine manufacturers have been installing new aftertreatment systems and technologies in response to a series of federal clean air mandates adopted by the U.S. Environmental Protection Agency to reduce emissions of nitrogen oxide (NOx), particulate matters and nonmethane hydrocarbons. These aftertreatment systems reduce emissions by treating exhaust gases after combustion but before they are released through the tailpipe.
An aftertreatment system is generally required to validate emissions levels.

Comptek’s custom aftertreatment test systems with software developed for your application are a critical component for OEMs and tiered suppliers to ensure emissions from engines comply with these environmental standards.

We have extensive experience in this area in working with exhaust system manufacturers to develop electronic test control solutions that meet progressively more stringent emissions regulations. ECU hardware design and software development, controls development, and support are our expertise.

These are typical exhaust aftertreatment system components and criteria that Comptek test software can monitor, acquire, and report data for:

  • Diesel oxidation catalysts (DOCs)
  • Diesel particulate filters (DPFs)
  • Selective catalytic reduction systems (SCR)
  • Catalytic converter ageing tests (on all liquid/gaseous fuels)
  • Particle mass testing (PM), particle number testing (PN), and solid particle size distribution testing
  • Urea dosage optimization for applications with SCR

Comptek’s ComETS Software Provides the Solution

Comptek’s latest custom Engine Testing Software ComETS meets today’s demands – integrating seamlessly with CAN-based control modules that communicate with other vehicle and engine control modules. Comptek can provide you with inexpensive, operator friendly computing solutions to solve your assembly and test requirements.

Hot/Cold testing. Multiple model engine adaptation. Ease of operator use and revision. Lifetime support. Comptek stands at the ready to design engine validation software customized to your requirements.

Comptek Production Engine Testing – ComETS is used to test engines in a production environment as part of the assembly validation process. In fully automated test cells, COMPTEK test systems automatically control the aftertreatment
test parameters into the test cells, start the engine, run a test sequence, monitor safeties, determine pass/fail and archive the test data in plant systems.

Comptek Engine Quality Audit Testing – ComETS is also used for Quality Audit engine testing – a process typically used as an over-check of the production testing process. The tests run on Quality Audit test stands are more comprehensive, typically running the engine for longer periods of time and collecting more data parameters than the production test. Parameter data is collected in time-stamped data packets to be analyzed by statistical analysis tools on a remote engineering or plant product engineering computer. The operator can select a predetermined test sequence to be run or manually run the engine at specific speed/load setpoints. ComETS has the built-in flexibility to run Quality Audit Testing for each of the different engines produced at a facility. The ComETS system also can easily be revised by the operator so that test sequences, procedures and parameters can easily be modified for new or special tests.

Comptek Engine Endurance Testing – ComETS is equally effective for testing engines over extended periods of time to validate endurance. Tests are set up to run event or time-based test procedures, collecting data periodically. Safeties are checked in real time, and product maintenance shutdowns can even be scheduled.

Exhaust aftertreatment testing is an essential and valuable tool to better understand engine emission performance and to optimize the whole system.
