DYNertia3 Dyno System (Inertia & 'open loop' brake dyno)

Finally, your own Dyno (Dynamometer) is within your reach!

Thanks to DYNertia3 the answer to the high cost of Engine / Chassis Dyno’s is at hand - build your own DIY Inertia and/or 'open loop' Brake Dyno! A Dyno is usually considered far too expensive or complex for most people - even if it's a straight forward Inertia design - the electronics and software necessary to make it all work effectively are just way too complex! Perfect for any one interested in engine / vehicle testing and modifying, whether it be kart, bike, car or even 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. The controller senses the velocity of the rotating mass, handles the precision timing required and outputs this data to the PC for analysis and display. No expensive 'load cell' or absorber required!  We have a guide and tools to assist in the designing and building of the inertia assembly, regardless of it being an engine dyno or chassis style.

Brake (absorber) type dynos use a mechanical load (e.g. water, eddy current, hydraulic, friction) against the engine and the torque applied is measured on your ‘load cell’. In ‘brake’ mode DYNertia3 uses this torque input rather than the inertia figure for power calculations. The basic DYNertia3 kit does not control the absorber (you need to control the load applied), it gathers the data, this means it is 'open loop'.

Even a precision rotational sensor ('Hall' effect) and magnet is included with the kit. No need for additional speed sensors and their associated ‘trigger wheels’. This method is both accurate and easy to incorporate into your dyno design.

So stop dreaming about having a Dyno to add that extra edge to your tuning - eliminate the time and cost of guessing what's going on with your engine.  And of course, if you run a performance business the extra trade generated by the Dyno facility will set you apart from your competitors.  It really is that simple, professional and cost effective!

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. 

• 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 and 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 runs.

What you may need to provide -

• Inertial mass or brake assembly (the actual mechanical dyno parts).

• For brake type you will need to have a sensor to provide torque input to DYNertia3. 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).

• PC with a USB port, 12V power supply (battery) for DYNertia3, associated wiring.
