Can a Clutch Plate Assembly Connect an Engine to a Dynamometer?

Click For Summary
A clutch plate assembly can be used to connect an engine to a dynamometer, allowing for engagement and disengagement of the shaft. However, decoupling the engine from the dynamometer can lead to rapid increases in engine RPM. It's crucial to diagnose why the accelerator pedal is not effectively controlling the engine RPM, as this may relate to fuel flow or torque regulation. Additionally, understanding the nature of shaft vibrations—whether transverse or angular—and ensuring the coupling is balanced are important considerations. Proper setup and diagnosis are essential for effective operation and to avoid potential issues.

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?

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?
 

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
