Engine & Dynamometer Coupling

  • #1
Can I use a Clutch Plate assembly along with drive shaft to connect Engine & dynamometer?

I am facing an issue where in CRDi engine, at a position of accelerator pedal RPM is increasing from 1300 to 2000 without any change in accelerator pedal position. And a lot of vibrations takes place at 1300-1400 RPM range, so in-order to avoid shaft to be subjected to vibrations for longer time, can I use a clutch mechanism to engage and disengage the shaft from engine?

Welcome to PF.

Can I use a Clutch Plate assembly along with drive shaft to connect Engine & dynamometer?
Yes. But if you decouple the engine from the dynamometer the engine RPM can rise very rapidly.

Different engines have different governors. You need to identify the reason why the accelerator pedal does not control engine RPM. It may be arranged to regulate total fuel flow or torque, rather than RPM.

Are the shaft vibrations transverse or angular? Is the coupling balanced?
