DYNertia Dyno System (Inertia &
'open loop' brake dyno)
Your own Dyno
(Dynamometer) is within your reach!
Inertia Dyno ( Dynamometer ) Software /
Hardware unit allows easy DIY construction of an inertia dyno (or 'open loop' brake type dyno).
Perfect for engine/vehicle testing and tuning, whether
it be kart, bike, car or even RC model sized engines.
Inertia type dyno operates on the principle of calculating the power required
to accelerate a known mass, which is basically just a 'flywheel' coupled to the
engine or vehicle.
Brake (absorber) type dynos use water, eddy current, hydraulic
or friction load against the
engine and the torque is measured on a ‘load cell’. In ‘brake’ mode DYNertia uses this torque rather than the inertia for power
calculations. The DYNertia kit does not control the absorber (you need to
control the load applied), it gathers
the data, this means it is 'open loop' only.
We have a
assist in the designing and building of the inertia assembly. All you need in
addition to this controller and the dyno inertia mass is a PC for the software (with a USB port).
precision rotational sensor ('Hall' effect) and magnet is included with the kit
so no need for a
‘trigger wheel’. This method is
accurate and easy to incorporate into your dyno design.
Key Dyno System Features -
Software provided handles all data management, analysing and graphing required
for your dyno project. Records Power, Torque, RPM/Speed, input channels,
math's, Slip and Losses channels and a second Hardware RPM input, all
conveniently displayed and stored on your PC or Laptop.
Software and firmware updates are free. Firmware updates from your PC keep
your hardware updated.
Dual screen compatible modes allow you to display 10 runs at once. You
can also pan, zoom, display speed, RPM, duration, sensor values, "merge"
(create an average), "join" and "trim" existing runs.
Suitable for chassis or engine
inertia and/or 'open loop' brake (absorber) dyno designs, either direct or indirect drive.
Completely flexible inputs, 5 analogue
& 1 digital, for sensors such as air/fuel ratio,
temperature, voltage etc.
2 additional data channels can be created to perform complex data
calculations ('math' channels),
just think of the tuning possibilities!
Metric and Imperial modes.
kph/Kw/Nm/ºC or mph/Hp/Ft Lb/ ºF etc. Data is also corrected for weather
conditions to world standards.
Dyno and Driveline mechanical 'Losses' can be measured and correction values
applied to the test data.
Powerful analysis tools are provided to get the most from your testing.
Overlay and analyse results or quickly replace with other saved runs for
comparison. Test data, conditions, max readings, set
up details or any of your personal notes that are saved along with each run
can all be reviewed. You can also view a summary table for all of the selected

What you may need to provide -
Inertial mass assembly (the actual mechanical dyno parts).
For brake type you will need to have a sensor to provide torque input to
DYNertia. This can be a load cell and amplifier (typically an 'S-beam'
type), the signal from a pressure sensor (hydraulic load cell) or a
potentiometer (mechanical load cell).
