STARS HDEET

Test Automation System for Heavy-Duty Engine Emission Testing

STARS HDEET is a Heavy-Duty Engine Emission Test application available as an optional extension to STARS Automation. It provides efficient test cycle execution, emissions equipment control, results calculation and reporting, in compliance with the different legislative standards. Its flexible design offers a wide range of customization while addressing the various requirements for research and development, conformity of production, and certification testing.

Today, heavy-duty engine emission testing is more challenging than ever before. We must consider increased complexity in emission regulations, new standards for greenhouse gases, in-service and real-world compliance requirements. STARS HDEET helps overcome this complexity by providing complete regulatory emissions certification procedures, using the flexibility of the STARS Automation platform to automate all kinds of engine development test work.

 

Segment: Automotive

STARS HDEET increases test cell efficiency and productivity from test configuration to final report generation, always keeping the highest quality level to give absolute confidence in the test results.

Powerful

STARS HDEET can be extended to run custom cycles and to control additional measurement devices which are needed when emissions test cycles are used as part of the base engine or calibration development process.

Flexible

With our proven experience in engine emission testing, STARS HDEET has been designed so that individual test options can either be selected by the operator for each test or taken from pre-defined default settings.

Efficient

Preloaded with regulatory cycles, configuration data and results calculations for a wide range of engine applications, STARS HDEET is a ready-to-use solution. STARS HDEET guides the user through the test configuration with minimal required input data, minimising the risk of configuration errors.
