The chassis dynamometer is suitable for testing the full vehicle power performance, emissions, fuel economy, range, reliability, and durability of two-wheel-drive or four-wheel-drive vehicles, including internal combustion, electric, and hybrid vehicles. It is widely used in component and assembly benchmarking, vehicle research, and quality control/tracking. By simulating actual road conditions with drums, accurately controlling load, and using environmental simulation systems to recreate vehicle operating temperature, humidity, light, wind speed, and pressure, it effectively shortens development cycles while being safe, reliable, and highly consistent.
