Rlangham Posted May 28, 2008 Share Posted May 28, 2008 On the old forum there was a topic about the Italian Pavesi vehicles, including the armoured car version armed with a machine gun - for those interested, i've found a photo showing the version armed with a 57mm gun, designed as a tank hunter Quote Link to comment Share on other sites More sharing options...
Tony B Posted May 28, 2008 Share Posted May 28, 2008 The italians at the time were world leaders in articulated vehicles. the Pavesi range were respected through out the world. They seem to have been ecilpised by Fabrique Italiano Automobilo Turiono (Showing off, got drunk at college with a FIAT tractor salesman, about the only thing I can sy when phissed) Fiat, who didn't start tractors till1918. they also specialised in 'Semi disiel' engines, can some one explain how they work please?

Great War truck Posted May 28, 2008 Share Posted May 28, 2008 I would say that was a doctored (or should i say enhanced) photo of a chassis under test. interesting though. Tim (too) Quote Link to comment Share on other sites More sharing options...
andreadavide Posted May 29, 2008 Share Posted May 29, 2008 The actual spelling is Fabbrica Italiana Automobili Torino, but if the FIAT man was drunk this may explain the misspelling 8-) 8-) 8-). Yes, the Pavesi Tolotti was incorporated as virtually all the motor prodution in Italy in FIAT. About the semi diesel tractor, maybe you are referring to warm head engines?

Rick W Posted May 29, 2008 Share Posted May 29, 2008 Another pic, with what looks to me like 88's being towed. Quote Link to comment Share on other sites More sharing options...

Andrea I'm the furriner now mate!:cool2: Used to have great fun when I was demonstrating Renault tractors, along withe FIAT guys we used to great delight in showing up the Fords. As for the engines, if they are known as warm head in italy, yes. how do they work? I've never been able to find out. Quote Link to comment Share on other sites More sharing options...
Runflat Posted May 29, 2008 Share Posted May 29, 2008 A quick search on the internet-thingy tells me that a semi-diesel engine operates on a comparatively high compression ratio and utilizes fuel similar to diesel engines; however it uses an electrical ignition system rather than depend solely upon heat generated by compression to furnish ignition.

Tony B Posted May 30, 2008 Share Posted May 30, 2008 Sounds very complicated, however I suppose if the vehicle has to work at high altitude in cold weather on poor fuel, it would need something like that. Quote Link to comment Share on other sites More sharing options...
andreadavide Posted June 3, 2008 Share Posted June 3, 2008 Allright, now I finally found the correct English term for the TestaCalda (literally warm head) engine. http://en.wikipedia.org/wiki/Hot_bulb_engine Andrea Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 3, 2008 Share Posted June 3, 2008 Understand now. Daft thing is I've seen these engines before. We had a Lantz tractor at college and on canal boats. It's the age mate, eh what was I saying? :confused: :n00b: Quote Link to comment Share on other sites More sharing options...
snowtracdave Posted June 3, 2008 Share Posted June 3, 2008 Hot bulb mostly used to be started by heating up the head with a big blow lamp - used to be one of them about here somewhere but somebody helped themselves to it some time ago . Aren't the semi-diesels the ones you start and run on petrol until they are good and hot and then turn over to diesel ? Quote Link to comment Share on other sites More sharing options...
Rick W Posted June 3, 2008 Share Posted June 3, 2008 Dual fuel...interesting.. Similar to very new cars which you can run on veg oil, one method is you have 2 tanks and start on normal diesel then switch over to your veg oil. Quote Link to comment Share on other sites More sharing options...

NO! You will destroy the high pressure fuel pump rapidly on most common rail engines if running on pure veg oil. It is also totally pointless as you are effectively evading fuel duty, so you might as well run on red diesel. Mike Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 4, 2008 Share Posted June 4, 2008 One of the points of hot bulb, semi disiesl whichever you call them. they will run on a variety of fuels. The most intresting I've heard of is coal dust. Liquids I can understand, but how do you inject coal dust? Quote Link to comment Share on other sites More sharing options...

Depends on individual car as well, Skoda Fabia Tdi OK, highly tuned Defender Tdi not OK. Not pointless as veg oil is a helluva lot cheaper than diesel, and red diesel is a little bit illegal unless your registered. Quote Link to comment Share on other sites More sharing options...
