I KNOW this is a woodworking site. I also know some of you appreciate this kinda nonsense.
For that little maintenance on that Saturday afternoon under that shady tree in the back-yard. Give that little kanutin valve a tweak with the giggle-pin and way you go. I just had to share this with a few of you dorkers.
Yup. It is a diesel. 650HP, approx 1000 ft/lbs of torque. (Check those dual intercoolers on either side.) Tested very well for 24 hours at LeMans.
For anybody who wants a more detailed (larger) image

It's OK, but I'd like to find one of these, so I could put it in a Jeep.

Diesels are starting to get installed in light aircraft, as well as race cars.
however that probably would not have left enough mass in the block to hold up as a diesel. Thanks for sharing.
They're re-thinking the push on that W-12 concept. The buying public if afraid of its complexities. Besides, it doesn't do much that a well- designed V-8 won't do.
BTW... a fellow who had his (early 70-s) Buick GS 454 ci sniffed at the polution control check-up found his was running cleaner than most of the new-fangled cars. Go figgur.
My daughter runs a diesel VW. A friend runs a 5-cyl turbo in his Benz wagon... both great touring cars. We drove that 300TD from Rochester NY to Montreal and back and you'd never-ever know that was an oil burner. Quiet, smooth as silk. I'm a believer.
A bit smelly perhaps. That famous knocking sound of a diesel might be a bit disconcerting whilst idling along a runway though..... and then that puff of smoke on take-off...
They run on Jet-A (kerosene), so they're not too bad, but I've only seen one.
Diesels have added safety factors of no carb ice, no electrical system, and less water in fuel issues, so I'm surprised it took so long. I would imagine that they could also run higher prop pitches at lower RPM, which would result in a quieter plane. Lots of noise comes from supersonic propeller tips.
The big advantage to to the W8 over a V8 is that it is pretty compact and fits into a smaller space. IIRC some of the VW Passats had W8's
That is something to think about alright. LOL.. Probably running very lean.
Not quite true that the diesels don't require electrical in planes, as shown by an accident involving a Diamond DA-42 in Speyer Germany earlier this year.
The DA-42 has an computerized electronic fuel control system. Kill the electrical system and the engines stop right now. What happened in the above accident was that, essentially, someone left the lights on. The pilots got it started by jump starting both engines. At take-off time, the battery (or batteries) were still pretty flat, and when they brought the landing gear up, the surge was enough to kill the fuel control computer and flame out both engines. Both Thilert (maker of the engines) and Diamond are looking at the problem.
And diesels in planes aren't necessarily new. Jumo made diesel engines for some of the larger Messerschmits during WWII. The were heavy though. Its only with modern metallurgy that diesels are starting to be made light enough for practical use in planes.
Don't they also have glow plugs or some thing like that to aid in starting a cold engine?
That was a FADEC issue and not necessarily related to the fact that the engine was a diesel, no? I was referring to the lack of magnetos and plugs when compared to gasoline burners.
I read the DA42 accident report, and it seemed that if the engines had manual controls, ala an experimental Cessna diesel conversion I've been hearing about, propulsion power would have been available.
No juice will kill any FADEC operated engine.
Yes.
True, strictly speaking it was the control system that failed and thereby killed the engines. However, as I understand it (and I could well be wrong) Thilert was unable to get the engines FAA certified without the FADEC.
It could be done without the FADEC (as in the cessna case), but getting it approved by the FAA may prove to be a bigger problem than its worth.
Have you heard or read what the FAA's concerns were without FADEC?
It's not like a screwy or dead FADEC system has _never_ shut down a turbine or gasoline piston engine. You'd think the simplicity of the diesel would be a plus.
I know the Cessna was flying around as an experimental, working toward certification and a possible STC.
Your friend should investigate modifying his Benz to run on vegetable oil. Gets rid of the diesel smell and cuts the fuel bill down considerably.
Since buying and modifying my own 300TD we've paid for maybe 2 tanks of fuel tops.
And that was only because we took it on a road trip and didn't want to carry all the extra veggie oil. With some better advance planning we could have easily arranged to buy either new or filtered veggie oil along the way.
Nice thing about the modification is that I can still run petro diesel or bio-diesel if need be.
John E.
And, it goes without saying of course, that you write a check to the government for the road tax on each gallon of that veggie oil that you burn. Otherwise, isn't it sort of like using off-road diesel fuel in highway vehicles? The PTB really frown on that practice.
We've got a bunch of bio-diesels in my area, including a few private busses. They get lots of press coverage with no complaints from the tax people so far.

Unless you've got a very small, hand started, Diesel, it's pretty much a given you've got some type of an electrical syste there somewhere. How about absolutely NO electrical system needed if so desired (starting with only a match possible), and the capability to run on about ANY burnale fuel?
JOAT What is life without challenge and a constant stream of new humiliations?

Maybe the tax agents are more diligent in heavy agricultural areas. A lot of farmers who run diesel equipment will buy off-road (red dyed) fuel in bulk sans fuel tax. It's awfully tempting to pull the diesel truck up to the farm tank and fill-er-up with the cheaper fuel. Just don't get caught with red fuel in an over-the-road vehicle. The authorities tend to get nasty about it.
Hard to enforce, 'though. Don't recall ever seeing a checkpoint with a cop dipsticking diesel vehicles to see if the fuel was red. Maybe there's a "probable cause" search aspect there. But I have been through driver's license/DUI checkpoints and it seems that would be much the same. Maybe an ROI thing.
