Lombardini 440cc Common Rail Concept

It is possible.

I am still waiting for the supplier to get back to me with more information

What are you hoping to get it for? Because I think that is a pretty important question I would guestimate it goes for several thousand euro.

[alexanderfoti]

I am not really interested in buying it, but would like to know how much it costs

I am expecting between 1-2000 pounds UK.

Got to love how much many of these engines jerk around the public. "Oh hey! We are building it." then you never really hear about anything in the pipeline and you forget about it. Probably looks good to the shareholders though.

I'll note that the engine's specs are quite unimpressive.

Like, BSFCs that a gasser can easily beat. Like, best case, 290 g/kWh at 2300 RPM (PDF page 18).

If you're gonna have BSFCs that bad, you might as well run a gasser, and get lighter weight and far lower cost.

What is bsfc?

[bhtooefr]

Brake specific fuel consumption.

Basically, this engine burns 290 grams of fuel per kWh at 2300 rpm at full load.

Compare to a Kubota Z482, which burns 260 grams of fuel per kWh at 2200 RPM. And the Z482 is indirect injection, even, which is typically less efficient.

Or a Yanmar L100N, which is aircooled (which typically reduces efficiency), although it is a single cylinder (which typically improves efficiency) at 240 g/kWh at 2600 RPM.

Or a Ruggerini MD151/Lombardini 25LD330, which is an aircooled twin, at about 258 g/kWh at 2850ish.

Many thanks.

I could have googled it, but was stuck on my phone.

That is interesting that its BSFC is much lower than the others, It appears as though they are trading fuel efficiency for driveability. I wonder why its lower?

Thats interesting to know that the L100 has such a good fuel effiency. That means, theoritcally, when I swap my L100 out for a Z482, my fuel efficiency will go down...

[bhtooefr]

Not necessarily.

Unfortunately, for industrial engines like those popular here, full-load numbers are usually the only ones given. At lower load, the Z482 may well be either less or more efficient.

Also, the Z482 may be overall more efficient even at full load but lower RPM, looking at the curve shape on the L100N.

L100N curve: http://www.yanmar.com.au/media/11257/l1 ... 0curve.pdf (and, my bad, that 240 g/kWh is at 2800, not 2600.)
Another Z482 curve, that shows it dipping down to 255ish: http://www.dieselenginemotor.com/kubota ... 4-z482.jpg
