Gas Compression

[Stephan]

I have a question, I am operating a drilling compressor with a 3412 Caterpillar engine and when I start the engine for warm up and I bring the RPM UP , the RPM is a little bit erratic. If somebody as a suggestion please let me know

Thanks in advance

Stephan - do you have anymore information?? does the rpm still remain "erratic" after the unit is loaded? ambient temperature? fuel pressure? mechanical or electronic governor?

[Stephan]

Hello CCRUZ,

The RPM goes back to normal after the unit is loaded, and now its running good. I checked the fuel pressure and the ambient temperature (no problem ) How can I find if I have a mechanical or electrical governor ? What usually give this kind of problem? The diagnostic tools doesn't shown error . The unit work good after the warm up.

Thanks for the reply, this is very appreciated.

We would have to know the serial number of the engine.  With the serial number, we can define how the engine was built at the factory.  Is this a diesel engine?
