Knock resistance rating for Natural Gas
Knock resistance rating for Natural Gas
(OP)
Greetings,
I am looking for the procedures to calculate the knock resistance rating for natural gases, required for Gas Engines °BTDC adjusting . Specifically, I need the calculation procedures for WKI (Waukesha Knock Index for Waukesha Gas Engines), Methane Number (Caterpillar Gas Engines) and n-Butane Number (White Superior Gas Engines).

Have you looked at this paper? http://www.google.com/url?sa=t&rct=j&q=&am...
This is the European Engine Manufacturers Association position paper on methane number calcs.

I find it quite funny when the gas engine packager wants to know the composition of the fuel gas in our rich gas gathering system so they can set the engine up. I said it's the same as the composition that I gave 6 months ago for the last unit. The engineer gets all excited and says it can't be, this compressor is going to be 5 miles away from the last one. I try to explain to the kids that the composition changes every hour if not sooner.

I've generated an open source method that very closely matches the measured MN data available in the public domain. It does have some limitations for 'producer gases' but should work well for most natural gas compositions. https://github.com/gchoquet/EngineControlSoftware/
