Compressor requirements for star-up air

[jeap]

Hi All!

Any one know what is a typical flowrate for start-up air in a reciprocant compressor for natural gas?

and what this air is used for?

Thanks in advance.

I'll make a leap of faith here. The air is used to drive an air motor that turns the engine to start the engine. On older intergal compressor engine sets the air was injected into the power cylinders with the fuel shut off in a sequencial manner to again get the engin turning so it would start.

De Ja Vu all over again. This is the same way thread1036-169995 started. Why don't we confine answers to there.
