Large Engine Testing Solutions

Integrated testing solutions for marine, NRMM, and heavy-duty engine applications

HORIBA provides integrated solutions for large engine testing, combining engine dynamometers, fuel flow measurement systems, altitude and environmental simulation equipment, emissions measurement systems, and test automation software.

Together, these technologies enable accurate evaluation of engine performance, fuel consumption, emissions, and durability under controlled and repeatable conditions.

Depending on the application and test objectives, large engine test facilities may require a combination of performance testing, emissions measurement, environmental simulation, and laboratory automation systems.

Designed for marine propulsion, non-road mobile machinery (NRMM), and heavy-duty commercial vehicle applications, HORIBA solutions help manufacturers, test centers, and research institutions generate reliable data for development, validation, certification, and regulatory compliance.

Large Engine Testing Capabilities

Engine Testing

Engine performance testing requires highly dynamic and precise systems capable of accurately reproducing real-world operating conditions. By combining engine dynamometers, fuel flow measurement systems, and environmental simulation technologies, test facilities can evaluate engine power, efficiency, fuel consumption, and durability with confidence.

Integrated altitude and environmental simulation systems provide controlled variation of pressure, temperature, and humidity, helping manufacturers validate engine operation across a wide range of operating scenarios.
