This exhaustive approach enables test vehicles to be evaluated as a whole, rather than focusing on individual components in isolation. Chassis dynamometer testing allows for performance testing under multiple load conditions, simulating real-world driving scenarios.
The dynamometer measures the entire vehicle's performance, including the drive system, energy systems, and other components, providing a complete picture of the vehicle's efficiency. Data acquisition systems collect and analyse data in real-time, allowing engineers to pinpoint areas for improvement.
Each component's contribution is refined, enabling the optimisation of the entire vehicle and leading to improved fuel efficiency and aggregate performance. This integrated approach guarantees that every component works in harmony, resulting in a more efficient and effective vehicle.
Most stringent emissions regulations necessitate the use of transient testing, a pivotal component of the emissions compliance process.
Transient dynamometers are designed to simulate real-world operating conditions, making them ideal for emissions compliance testing. They accurately replicate the dynamic load patterns of real-world driving, ensuring exhaust emission measurements accurately represent engine operation.
Transient dynamometers exert and absorb any specified load to or from the engine, replicating real-world operating conditions.
