Other Fuels / Used Refrigeration Oil
« on: December 15, 2019, 09:35:11 PM »
I have an opportunity to get some used refrigeration oil for my Changfa.  It looks like the older stuff is mineral oil which should run fine but will the newer synthetics burn?

Waste Motor Oil / Measuring Running Engine Load
« on: June 18, 2019, 08:37:13 PM »
I'm working on a project where I will be using a Changfa 195 burning
waste oil to drive a DC generator which in turn will power a grid tie
inverter and also an air compressor to supplement my main compressor
since it has excess hp over what the generator needs.  I've read that
engines do better running hard and hot on waste oil.  Do you have any
ideas about how to measure running load on the engine so the load can be
kept fairly heavy using a heating element?  As a pilot, my first thought
was to measure manifold pressure which gives a good indication of engine
load on an airplane with a constant speed prop but diesels don't have
manifold pressure per say.

Other Fuels / Hydraulic oil mixed with automotive oils

I'm having a very hard time finding WMO.  Would a Changfa burn a mix with a large percentage of hydraulic oil mixed with various automotive oils?  Another option might be a hot bulb engine but would it react to the fuel about the same as a regular diesel?

Things I want to Buy / Looking for a 6-1, JP1, Changfa 195s

I'm looking for a 6-1 or JP1 or Changfa 195s ideally located somewhere near Oregon.  I'm open to others in the 6-15hp range with indirect injection.
