Emissions Compliance
Validate performance against global emissions standards
As emissions regulations tighten and real-world compliance requirements increase, validating emissions at the full vehicle level has become more complex. Engine testing alone is no longer sufficient to capture how heavy-duty vehicles perform under real operating conditions.
Heavy-duty chassis testing addresses this challenge by enabling complete vehicle evaluation, including the interaction between the engine, drivetrain, aftertreatment system, and vehicle load. By replicating real-world driving conditions in a controlled environment, manufacturers can generate accurate, repeatable data needed for development, validation, and certification.
Heavy-duty vehicle chassis testing enables accurate emissions measurement under simulated real-world driving conditions. By reproducing vehicle loads and transient cycles on a chassis dynamometer, engineers can evaluate performance with high repeatability.
This approach allows:

Heavy-duty chassis testing measures vehicle emissions and performance from complete vehicles—such as trucks and buses—using a chassis dynamometer to simulate real-world driving conditions.
It enables accurate and repeatable measurement of regulated emissions—including NOx, CO2, particulate matter (PM), and particle number (PN)—while evaluating the interaction between the engine, drivetrain, and aftertreatment systems.
Heavy-duty engine testing evaluates emissions and performance from the engine alone using an engine dynamometer, while heavy-duty chassis testing measures emissions from the complete vehicle using a chassis dynamometer under simulated real-world conditions.
Heavy-duty chassis testing is important because it captures the interaction between the engine, drivetrain, and aftertreatment systems, enabling accurate measurement of regulated emissions such as NOx, CO₂, particulate matter (PM), and particle number (PN). This full-vehicle approach supports development, validation, and compliance with global emissions regulations.
Chassis testing measures vehicle emissions in a controlled laboratory environment using a dynamometer, while on-road testing evaluates performance under real driving conditions.
Chassis testing provides repeatable, high-precision measurement of regulated emissions such as NOx, CO₂, particulate matter (PM), and particle number (PN) to support development and certification.
On-road testing validates these results in real-world conditions, helping ensure compliance with evolving regulatory requirements such as real driving emissions (RDE).
