Fun conversion anyone?

Don't know if this will fit but should be quite a goer?

Its only a 90 not a 110 bhp - so about the same as a 1.9TD in theory - but may be better at low revs as it may have better control over the turbo and boost lower down. This refinement may only be on the 110, together with the intercooler, 6 outlet injection nozzles and maybe some other useful bits.

Anyone buying it should make sure they get the ECU and its loom and other associated engine wiring.

would be a good fit if you towed big caravans

Is the HDi a XU based engine or is it completely different?

jeremy · Post by **jeremy** » Fri Jul 20, 2007 11:11 am

HDi is a later engine - working slightly differently - in that its a direct injection engine - which means that the fuel is injected directly into the combustion chamber rather than into a small pre-chamber where it ignites , passed through a small hole aned then into the main combustion chamber.

Surprise surprise - direct injection is more efficient than indirect which is why everyone built indirect injection small engines till about 2000. (I lie - I think Rover/BL with the help pf Perkins produced a direct injection for the Montego a few years earlier.)

I'm not sure if you'd call it a new engine as I think the crankshaft is the same part as used on a XUD - but its very substantially different and uses more modern high pressure injection (XUD struggles after a number of mods to about 1800 psi - this is 10,000 psi)

Are these engines the same as 'common rail' diesels Jeremy? I wonder why they changed from Di diesels to the newer type, was it some sort of emissions/economy based factor?
Incidentally I'm a long term fan of the Perkins two-litre, especially the TD unit. Fantastic things imho.

Sounds like a bag of spanners in a washer but will go on for ever!

Pulls like an absolute train too. Still planning on getting a Maestro with one in one day.

The Hdi motors pulls like a train

we had to move some cars a few weeks ago and while the Bx did ok with the 2cv's on a big and heavy trailer

we had to hire a trailer for to move the biggest one (1.5 ton plus trailer)

we thought that we would some problems but the berlingo took it all in it's stride up hill ot down dale it's all the same for the Bling

the last time we towed it was with a VW sharan and that had to work hard and made some very worrying noises

Billy - you're right - the HDi does use a common rail supply for the injectors.

There's nothing magic about the rail itself - the fuel is fed at high pressure and the appropriate injector is fired at the appropriate time electronically. This obviously saves some considerable complication in the pump and also enables several injections of fuelto be fed into one cylinder on one stroke. The HDi 110 has 6 hole injectors - which provide 3 pulses at low speeds - which enables the typical diesel clatter to be reduced. Apparently as the revs rise the injectors revert to a single pulse.

Nothing's new - Mercedes who made very expensive and rather slow large cars with small diesels in the early 60's didn't use the Ricardo comet combustion chamber (as used in the XUD) but a thing with what looked like a pepperpot top separating the precombustion chamber from the cylinder - with the intention of reducing the noise. I think it was abandoned as it was thought to reduce the (already low) power still more.

Power of these things is interesting. One of the most powerful in the 60's and 70's was the 2.25 Rover diesel as used in the Land Rover. In fact it produced about the same as a 1.9 XUD (by 1987)

23 destructions under my belt now! But we've run out at the farm, need to find more vans to destroy!

Tim, to simplify the responces, yes its an XU derivative and will fit in the same space. THe accessories though are the problem and will create complication when considering a drop in option. Typically the gear boxes are different, but a BE3 TD box shoudl fit

BX HDI Anyone?

rob-bx16v · Post by **rob-bx16v** » Fri Jul 20, 2007 5:44 pm

bx hdi with increased boost and dumpvalve anyone??

and before you all lynch me that was a joke

tim leech · Post by **tim leech** » Fri Jul 20, 2007 7:01 pm

You can scoff rob but I bet you get it up to 16v figures with the right mods, I work for VW and they can get oevr 200bhp out of there 2.0TDi engines with some fiddling!
