I thought the intake flap in the Detroit diesel was put there to stop it running backwards (which it would quite often) and not solely to stop runaways.

you sure you been in the game as man and boy. Were have you been in 40yrs not to see this happen■■?
Probably stuck in a time warp and thinks Gardner engines are not the over engineered underpowered pieces of crap that they were. 
and yep I’ve had experience of shovelling up the aftermath of blown straight 8 engines on the hard shoulder too . To be fair they wern’t runaway engines, just crap IMO
Nah just sick of hearing crap from labourers with a bloody licence who spout crap or old men who couldnt cut the job so went to “drive” a truck instead.
I still play with the things I know how they work.
Most of the plantpots on here still think we got injection pumps and engine stop solenoids.
Keep up boys FFs things have moved on.
[zb] amateurs.

Muppet get back to the museum where you belong eh.
Guarantee he’s an apprentice fitter in a Tesco fleet workshop. The whole time he’s posting his ■■■■■■■■ on here there’s some poor bloke holding a spanner in a pit waiting for his cup of tea.

Lol,
You never know the real mechanic might have sent him for a long stand and he’s posting his crap via his mobile while stood waiting

Ah yes, the old visit to the stores for a long stand. A christmas cracker

Maybe engine oil is the fuel of the future eh.
It is already used for that purpose - but generally only as a means of recycling used oil. It makes no sense at all to use new engine oil as a road fuel, as it costs more to produce than conventional diesel and it is much more difficult to get it to burn cleanly, especially in an internal combustion engine (easier to burn it externally to heat boilers etc).
You can get workshop warm air heaters that run on waste engine oil.
it would upset the ones with optical sensors , otherwise many engines will run on black diesel
the army still use engines that will run on just about anything ,multifuels
Don’t big marine engines run on, thick oil? I seem to remember reading that it has to be heated before it enters the engine to thin it out
Yes Bunker oil No.5 or 6 HFO (Heavy Fuel Oil)
Think I read somewhere that fewer modern ships burn it as diesel electrics like the Queen Mary 2 become more common. There are no prop shafts and the engines burn gas oil to power generators which in turn power the motors on the azipods.

Wouldn’t need any extra hot air when Burgerkings sweeping the Worksop

Just one problem with this theory as well.Ship engines that run on “heavy crude” heat the oil to about 500 degrees before injection.
Dont see many high speed diesels with 100 kw heaters in the fuel tank though
And as for a 2 stroke diesel running backwards oh dear we are in fantasy land now.We are talking diesel 2 strokes here not some bloody BSA Bantam,
Driveroneuk:
Correct. The strain on the driveline would be terrific in 1st gear with a say 440 horse engine revving at what, 5 - 10,000 rpm?
Love to see a 12 litre diesel rev to 10000 rpm.
Is this one of those they fit in GP cars.Even 5000 would be nice.
Jesus!
Well this 650bhp V12 diesel revs to 5,000 and beyond.
Give a diesel engine an unlimited air supply and almost unlimited fuel supply, which is what happens in the instances being discussed and it will rev to the point of destruction.
The R10 may well be a V12 - but it’s nowhere near 12 litres

Didn’t say it was but know all, sorry BurgerKing did mention car engines.
Mr King how can you deny it is possible for this to happen when there it is doing just that in the video examples above?

In the video the turbo charger fails,the main oil gallery that feeds the crank also feeds the charger.The charger now is an open drain for the oil pump.The pressure drops to zero in the main gallery.The crank is still rotating at 25 revs per second at 1500 rpm.No oil pressure is fed to the mains therfore no pressure to the big ends.Contact happens between the end shells and the crank journal.Heat is produced and the shells weld themselves to the journals,they then spin in the con rod eye producing more heat.This causes the big end bolts to fail and the rod punches through the block.
What colour smoke is produced? White smoke which is diesel without heat as there is now not enough air as the turbo is not pumping into the cylinders so the diesel cannot be burnt.The heat is produced by compressing air.
If it was oil burning it would be blue smoke.
And as for comparing the Audi engine with a bloody truck engine well!!!The audi engine alone is worth more than a whole bloody Daf tractor unit and its trailer.

Speak to any Lister Petter engine owners- they were/are well known for sucking up the sump oil and blowing themselves to bits- no diesel required once its started to runawayAnd the reason you use a higher gear to stall simple by stalling that way you are putting less torque through the clutch minimising the risk of destroying it,
How the hell you putting less “torque” through the clutch?
Same engine,same flywheel,same clutch ,same gearbox.The “torque” is supplied by the engine.If the input shaft is locked does it make any difference which gear is selected.
And when was the last time you saw a Lister engine with a blower?
The Lister used unit pumps and oil got into the pump gallery .This was then “injected” into the engine and didnt “magicaly” appear in the cylinders from the sump.Explain why the input shaft is locked then? Because the handbrake is on? That would be the output shaft
And in a 16 speed for example you have 16 ways of trying to make stalling less stressful on the clutch, number 16 being the one to go for.Actually if you wanted to be really ■■■■ about it, it’s the brakes that are held solid. Everything else will have a dgree of movement. So in first gear you will wind up the gearbox, driveshaft, diff and half shaft before cutting out. But I agree it will cut out. However in top gear the wind up is less because higher gears reduce power to ground.
It’s why you change down gears going uphill.
Because its a “gearbox” if you lock the output shaft the input shaft has to be locked thats why the engine stalls for christ sake.What is wrong with you people?Dont matter what gear you are in,if the prop cannot turn,and a gear is selected then the input cannot rotatecan it.
