Natural gas vs Propane hp derate
Natural gas vs Propane hp derate
(OP)
I'm being told if you make a switch on a spark ignition engine from Ng to Lpg you need to hp derate. Same engine at stoich on both LPG and NG. This just seems counterintuitive to me but I've been wrong before.

In some older Caterpillar (and some Waukesha) models there were dual fuel configurations with different fuel trains and switchable ignition timing to support the fuel change, and in some cases a power derate was applied when operating conditions and fuel quality put us in detonation on propane. CAT had an older nice EDS sheet (Engineering Data Sheet) on the topic but can't find it and can't get online with the system now.
Hope that helps, Mike L.

BTW, everything said above by catserveng is on the money, in my book.
