Engine test bench

  • Product Description

  • Overview

    Engine test benches can be classified into different types based on the dynamometer used: eddy current dynamometer, water eddy current dynamometer, and electric dynamometer. Eddy current dynamometer and water eddy current dynamometer test benches are mainly used for engine reliability and durability tests, while electric dynamometer test benches can be used not only for reliability and durability tests but also for engine bench power performance, economy, emission optimization matching, engine component testing, and optimization calibration during engine R&D. They can also perform dynamic development tests of engines through whole vehicle and road simulation, and meet the latest engine product certification tests according to Chinese, American, Japanese, and European regulations.

     

    Test Content
