Objet: Rotax 914 Fuel FLow

 I'm trying to get our fuel computer working properly.  I have 

 transducers on the fuel going into the engine and fuel being 

 returned to the tank.  What is the fuel flow others see at these 

 places at reasonable power levels, say 70, 80 or 90%?  Mine seem 

 to top out at about 35 gph but I think that's a calibration problem.

 


	


Jim,



The fuel flow vs power numbers are in the Rotax 914 Owner's Manual.

We cruise at 75 % power, with 20-21 L/h FF.

At 115 %  the fuel flow is in the 33 L/h range.

Maybe your instrument reads in liters, or something  is wrong with your return transducer. Note that 35 gph seems not unlike the total flow through the system, engne consumption plus return flow.



FWIW,

Regards,

Gilles Thesee,

Grenoble, France
