Loaded Dyno Pull

Heating

Before testing it will be necessary to warm up the engine - or the entire vehicle on roller dynos - to reach a stable working temperature. The tires increase their pressure at higher temperatures and at a higher pressure of tires, there will be less losses.

Temperature greatly influences power, so it is important to always work at stabilized engine and wheel temperatures.

Perform test (manual method)

  1. Bring the engine below the initial RPM that we loaded in the Test Data form. We suggest around 200-300 RPM less.
  2. Apply load with the dynamometer load control, either a command from the power source or a valve in the case of hydraulic dynamometers.
  3. As load is applied, the RPM will seek to drop. To compensate you have to gradually throttle the engine.
  4. There will come a point where we will already be with the engine at full throttle. Now we can start the power pull.
  5. To start press the external switch or the space bar which has the same function.
  6. In order for the RPM to increase, you must remove the load, decreasing current in the case of eddy brakes or closing the water valve in hydraulic dynamometers.
  7. The system will begin to record data when passing the initial RPM.
  8. The test ends when the engine reaches the final RPM or you press the external switch again to stop the recording manually.
  9. Once the test has entered the Finished state, we can now shut down the dyno and release the engine throttle.

Testing

REMOTE CONTROL

At the end of the test, it is possible to enter Graphs or Report screens by pressing the external switch again. Successive presses on the remote control external switch will change the screens until returning to the Test Data form and the system will be ready to carry out a new test.

To retest press the New button and load the data you want to change and repeat these steps.
