Changfa/Listeroid fuel consumption
« on: January 23, 2007, 04:56:54 PM »
I have just started using the Changfa 1115 engine with a 10kw ST Head to power our new house. Our power demands have risen some but not really very much. Anyway the old Listeroid GM-90, Satyajeet with a 12kw ST Head would run 4hrs on a gallon of fuel under 80-90% load. It ran at 765RPM, was set up for 750 but need a little extra to keep the voltage up under load.
The new Changfa uses more fuel, not sure just how much more but it is a noticeable amount. It is running at 1800RPM and powering a 10kw ST Head. Has anyone on this forum run one of these engines enough to get a fuel consumption rate on it?
Thanks ….Ken Gardner

Hi Ken,

I have done some crude tests with my Changfa 195.  With a 5kw load, I use about .127 gallons of WVO per kwh of power generated.  My measuring technique involved a dipstick in the tank, so there is bound to be some error.

Here is a site http://lerch.no-ip.com/ChangFa_Gen/ Where some more detailed fuel comparisons are done on a Changfa 1115. 

Here is a graph from his page:


The peak efficiency is at about 9kw where he is using about .09 gallons/kwh
