DYNertia2 Dyno System

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

Thanks to DYNertia2 the answer to the high cost of Engine / Chassis Dyno’s is at hand - build your own DIY Inertia and/or 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.

An 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!

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 DYNertia2 uses this torque input rather than the inertia figure for power calculations.

Even a reflective optical rotation sensor is incorporated with the controller. No need for additional expensive 'hall' or 'inductive' speed sensors and their associated precision ‘trigger wheels’. This method is both accurate and easy to incorporate into your dyno design.

We also provide a comprehensive guide and tools to assist in the designing and building of the inertia assembly, regardless of it being an engine dyno or chassis style. In addition to this controller and the inertia mass you will need a PC with a USB port.

DYNertia2 kit includes software to handle all the functions required for dyno operation: setup, saving runs, correcting for atmospheric conditions, filtering, displaying data, printing, overlaying and analyzing multiple runs.

Key Dyno System Features -

• Software provided handles all data management, analysing and graphing required for your dyno project.

• Suitable for chassis and engine inertia & brake (absorber) dyno designs, either direct or indirect drive to the inertia flywheel.

• Integrated optical sensor (reflective), each rotation is timed to 1μs (1 millionth of a second).  No expensive sensors or 'trigger' wheels required. 

• Completely flexible inputs, 5 analogue & 1 digital, for sensors such as air/fuel ratio, temperature, voltage etc. 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.

• Powerful analysis tools are provided to get the most from your testing.  Overlay up to 5 power and torque graphs at once or create a brand new 'averaged' run.  Analyse and compare 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.

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!
