fuel flow indicates zero - engine keeps running

What is the fuel flow indicator? In the US model, there is not an indicator of whether fuel is being injected to the engine or not. Are you referring to something on the HSI screen or the energy flow diagram or what?

The gas engine will turn whenever speed exceeds 45 mph to protect the MGs. Gas engine will also run (with fuel consumption) during warmup or to meet other demands such as low SOC or high demand climate control, etc. Winter warmups are longer and more frequent, so the engine runs more.

 

Not sure as well, what FUEL FLOW INDICATOR your talking about?
Are you referring to the Engine Running Indicator????

Please clarify...

 

Must be one of those special Canadian options....

I guess we'll have to have a new acronym if this is the case: FFI

 

What fuel flow meter? Are you running CANview?

My JP 2010 Prius comes with "Energy Monitor" screen instead of any fuel flow indicator.
The Energy Monitor displays the energy flow, not fuel flow nor engine running.
It is well-known behavior the Energy Monitor does not always display fuel flow, such as warming up period.

After looking at your picture link, this is not a Fuel Flow Indicator, but is a Instantaneous Fuel Economy guage.

Mine on many occasions will be at "0" even when the car is running.

I don't think this is a glitch at all.

It's working as designed.

Thanks for posting the link to a PICTURE for review.

 

Oh, the instantaneous MPG indicator. That's normal while it's warming up.

Think about it, it's going to get crappy (near 0) mpg during that time.

 

Remember that the Rest-of-World liters/km display will be inverted from the American MPG display. When Americans see it topping out at 100 MPG, Canadians should see it bottoming out at 0 L/km.

 

I understand now. Maybe the instantaneous MPG (or liters per 100 kilometers) display is designed not to operate (read as 0) during warm up. Naturally it would make sense if it's MPG but not liters/km.

 

The original posting was about low temperature operation but the questions do not cite ambient temperature. I regularly see 'no fuel flow' indications on the instantaneous mileage display while going down hills above 46 mph with the engine still 'running.'

I suspect the original posting was seeking some other condition but one can only answer the poll.

Aren't most polls like this?

So, OP, what does this i-consumption bar normally do during warmup when you are sitting still with the ICE running? L is non-zero, distance is zero, so the math is undefined (divide by zero error) for L/hkm, right? Does this normally show as a full bar or a zero bar or something else? To me, a full bar makes most sense.

Many of us 'down-under' would prefer consumption to mpg, but have no way to know what is normal in a consumption display. Canadian and other non-US drivers, are you seeing this?

 

I think what the OP wanted to say is as follows:
- in the energy monitor screen sometimes it might be that the engine is running when idle and the battery does not charge at all and no arrow is shown - even if the battery could be recharged since it is not full - question is then, can and does it make sense that the ICE runs without recharging the battery at all? or is it a Energy Flow screen bug?
- moreover, and this is not a bug, in the EU/Canada version the instant fuel consumption meter, in L/100km, shows 0L/100km when the car is moving with the ICE off and when the ICE is on (e.g. warming up) but the car is not moving - this is correct, since the gauge is showing the fuel consumption to move the car and not the L/hr (liters per hours - my Polo would switch from L/100km to L/hr automatically when the speed was 0km/h) - nevertheless the average fuel consumption is accurate, since the fuel consumption history will show a full bar (ie. >=10L/100km, ie infinite) if the car was standing still with ICE on for 1min - or less if the car moved in the meantime (it is a 1min average, after all!). Km/l is similar to MPG in terms of math and give a better representation of car still/ICE on situations. In Japan, if I remember Ken's HSI screen, does compute everything in km/l. Too bad I cannot switch the display to that!
