Chassis dynamometer VS 4-square test

Chassis dynamometer VS 4-square test

Chassis dynamometer VS 4-square test

Hi all,

In our lab, a little engine test-bed is available and we also run full vehicle traction test on our tracks. Our plan is to increase the type of activities we can carry out, so I am thinking to buy another test-rig. I am considering two options:
- chassis dynamometer: to run traction tests in the lab rather than in the track.
- 4-square test-rig with two dynos

In my mind, it is not clear the real pros and cons of the two rigs. I understand with the former the load is applied to the wheels and a full prototype has to be tested, while with the latter, we can also test a not fully working prototype. But, I do believe there are also some other differences, right? I haven't gotten a clear answer from a local sales manager.


Best regards.

jgKRI - the op said 4-square, not 4-post.
