- Serow225 11y agoNot necessarily, it could be a rolling road, which is more similar to what the OP described.
- dsmithatx 11y agoA rolling road is another term for a chassis dynamometer.
- jackgavigan 11y agoI thought a dyno is a mechanism that a standalone engine can be rigged up to on the bench to test it under (typically computer-) controlled conditions, measure its output, simulate different driving conditions, etc.
- schwap 11y agoIn N.A. generally that is referred to as an "engine dyno", and what's known in the UK and other colonies as a "rolling road" is a "chassis dyno".
- evm9 11y agoI've never heard any term except dyno (or dynamometer), but I much prefer those terms simply because it's more apparent to someone that doesn't have an understanding of engine & car testing. I'm a fan of names that give insight into what the thing/product/service/company actually does.
- aidenn0 11y agodynos can measure at the engine (in which case they measure brake horse power) or at the wheels. Most individuals are more familiar with the ones that measure at the wheels, as that's how they would measure the effect of after-market modifications.

- gregpilling 11y agoHere is what I would call a chassis dyno http://www.maha.de/roller-function-tester-fps-2700.htm http://www.maha.de/roller-function-tester-fps-2700.htm These are very very noisy, because the tires are moving at 70 or 80 mph (whatever you set) and make as much noise as tires going 70 down a highway (only 1 axle though!) A rolling road is different in that the floor moves under the car, not just rollers under 1 or 2 axles. Like this http://www.qmtmag.com/images/Windshear_RR_05.jpg http://www.qmtmag.com/images/Windshear_RR_05.jpg The chassis dynos are noisy, these are super noisy. Disclosure: I sold Maha dynos from 96-2000 with SnapOn/Sun branding, about 40 of them.
- grizzles 11y agoSo that's what they are called. When I worked for Chrysler everyone in the plant called it the rolls machine.
