Re: [Amel] Fuel burn rate


Thanks Danny, on our last Atlantic crossing motor sailing at a1400 our speed w/10 kts wind was 7.5 burn rate 1.5 l/hr. At 2200 8/l/hr
Average bottom some build up. Did not push to turbo.
Lube oil needed after or during crossing zero. We use synthetic oil designed for diesel as lube oil.
Thanks again.

Hi Richard, on a previous boat, a 42 foot racer/cruiser I had a volvo 2030 30 hp. At 2000 rpm and 5 knots boat speed the consumption was 1.2 (one point two) litres per hour. At 2500 rpm and 6 knots speed the consumption jumped to 2.2 litres per hour.

Hi Kent, I was wondering what kind of fuel consumption are you seeing. And do you often run you TMD at full power and for how long.
Most of us are concerned with our clean burn rate. At sea we often motor sail at around 1500 just to conserve fuel for the long haul.
When you press it at 2800 or so do you see any over heating or black smoke or increase crank case oil consumption?

Be interesting to chat about someday.

Thanks, Danny, already been there and done that.  Wish it'd been that simple for me.

Hi Kent, after discussion with a Volvo tech at St Maarten I corrected the code setting on the tacometer to match the motor and immediately achieved a 300 rpm improvement from 2500 to 2800. There is a recessed button on the back and you scroll through to the correct number for your motor model. Mine was miss set.

Fine, tell me more after this job,
Try to ask him his opinon to increese the power by 1/4 of turn of gas
oil rate,
if possible try that with this guy,
bonne chance

Thank you again Jean-Luc. Very interesting reading. I'll let you
know what I decide on after I have a Volvo service mechanic look at
the engine one more time.
I am currently in St. Maarten in the lesser Antilles and will be going
north thru the Virgins and Bahamas to the Chesapeake by June 1.
Probably won't get to the Med until after I go thru the Panama Canal
and do the Pacific for a few years.
Again, thank you for your interest and help.

The principle of the injection pump :

1 - If you have air (turbo ok) and gas oil (injection pump ok) you must
have power
2 - My opinion and only mein is that the engine (tmd22) is not in
accordance with my propeller.

To solve MY problem without to pay to much I increase only a very little
bit the power (if you put too much power the cooling system is not
sufficient we have a tmd and not a TAMD),
If you have a engineer culture you can do that by your self if not find
a VERY good mechanical (like one for truck, not necessarily a VOLVO

Read attached files it will help you to understand your engine,
Hoping that can help you,
are you in the Med area ?

Merci, Jean-Luc,
I already had the injectors and pump removed and sent to Volvo service
center for inspection, cleaning, and adjustment. No change in
performance was noted. After repitching the fixed prop I was able to
get 2850rpms, but only 7.5 kts. After only a month I am now only able
to get 2650 rpm with the same prop. KRISTY is on the hard in St.
Maarten getting a new bottom paint job. I'll be interested to see if I
can again get 2850 with the bottom and the prop cleaned. If it still
max's at 2650 I have to assume that I still have a problem with the
Volvo. I plan to find a Volvo service center on the Chesapeake and have
them evaluate the engine one more time anyway. If I'm back to 2850,
I'll have the autoprop repitched to allow 3000 rpm.

I'm not really clear on your post about "Increase the power (one YOUR
risk) of the engine by changing the injection". I looked at the link
but my French is so bad that it wasn't much help. Have you altered the
injection pump to feed more fuel to the engine to gain more power? At
what "risk"?

Merci, again,

I have exactly the same configuration as you (SM316)
With a new turbo, boat cleaned, injectors cleaned etc etc ...
On the best sea that you can imagine I can retch 2850 rpm and a spead
of 8.25 knds
AND THAT IS NOT ENOUGH !! the power of the TMD22 is at this point
around then 40 HP !!
Conclusion : the seize of the autoprop is too big !

What you can do :

1. put a smaller prop (or re-pitch the autoprop)

2. Increase the power (one YOUR risk) of the engine by changing the
injection .... see my post (Bosch pump) it 10 minutes work !!

3. buy a AMEL 54 :-)
