I thought this thread had runaway.
Rikki-UK:
I would to think that Bking will come back to this thread and admit he was in error - it would show that he is willing to learn something new, a talent that every decent mechanic should have- and to my mind is the difference between a mechanic and a fitter

You keep drivin them trucks boys! Now that the minimum wage is rising you will only have to work two hours to buy a bag of fish and chips or a gallon of diesel.
The laws of physics never change and neither do the dumb buggers who cant understand them.They always have and always will spout crap.Instead of thinking about a problem using logic they jump to conclusions.
A natural gas engine still has to have diesel injected in to ignite a volatile gas and now your telling me that oil pumped into an engine will âexplodeâ just at the right time to make an engine run itself to death by spontanious combustion.
And some who comment call themselves âmechanicsâ FFs.âIve done 2 years at school and I knowâ .You know [zb]
The biggest problem facing diesel designers was how to raise injection pressures to overcome cylinder pressure to get the fuel in to the engine at the right time,if you could just let oil get blown in at any point on the induction stroke why bother building a bloody injection pump.
Now somebody tell me how a blown turbo makes some engine run itself to destruction by not causing a loss of oil to the crank.

So why do you keep posting if you know youâre wrong?
Out of all the people that have replied to this thread you are the only one that agrees with your theory, others have posted their first hand experience and videos as evidence yet according to you they are still wrong.
And quite rightly any monkey can pick up a spanner and call them selves mechanics and still be crap, and even hold out in the job for a few years to say they are experienced, but experienced in what? Making tea and coffee?
If you are so sure youâre right come back with actual evidence to back up your claim, or go and post the question on a mechanics forum. If you can prove youâre right and everyone else Is wrong I for one would apologise.

A Snap On tool if you will. Sorry.
Lol, he ainât even that Luke , he sounds more of a Halfords special tool . 8 pages later and we are still all wrong despite peopleâs evidence to suggest otherwise. Come on Burgerking prove us all wrong
Mr King, earlier in this thread there are several links to videos of runaway engines running purely on inducted oil. We will assume that in all cases the ignition has been turned off, thereby switching off the live feed to the fuel solenoid thus allowing it to closeâŚ
I have just one simple question: what are these engines running on?

Because if you ran a bloody engine on a lube oil for any length of time it wouldnât last very long due to carbon build up and I would suspect the ole bill and VOSA might have something to say about the emissions dumb ass!
Bking:

Every turbo charger on the fricken planet has its own high pressure oil feed from the oil pump to the bearrings in the turbo. If said bearings fail, this high pressure oil feed â â â â â â past the knackered bearings of the compressor side of the turbo straight into the inlet tract.
This oil will be very hot and like â â â â â it will readily burn in the cylinders just like diesel.
The one little point where you nearly answered your own question was, after its been running flat out off its own sump oil, it will in the end run out of oil and the engine will either seize of throw a con rod through the side of the block.
Do you get it yet?
Short of drawing you a bloody picture, how simple do you want it?

Yeah, come on Bking, WTF are these engines running on??
I just gota hear the answer to this!
Maybe Bking can invent an engine that runs on fresh air alone?
â â â â me sideways, maybe they are running on fresh air and theres us idiots that have bought trillions of pounds worth of fuel since the invention of the compression ignition engine where all along they can actually run on fresh air!

Bking the inconvenient bombshell for that argument is that you donât need direct injection to run a diesel engine.It will run with indirect fuel supply into the inlet manifold upstream of the inlet valve on the induction stroke just like a petrol engine hence no compression pressure needed to be overcome to get fuel,in this case oil not diesel,into the cylinder.Itâs just that it wonât be running anything like efficiently because of the zb fuel air mixture and the ignition timing.But the fact is the compression will still ignite that zb fuel air mixture.Hence all the smoke.

Something else youâre not too clued up on!
Folks you have no hope in hell of burger king admitting he is wrongâŚHe just looks for a reaction from people âŚBest thing you can do is donât respond to his post .This thread I say proves that he wonât admit he is cluelessâŚThere is no need to justify yourselfs to him
Bking have you ever tried to get started a very old (think 20 - 30 years or more) diesel engine that has been stood for a very long time and had it running only on easy start sprayed into the air intake?

Itâs probably a waste of time because biking obviously thinks that nothing except air can get into a diesel engine on the induction stroke and any type of fuel,like ether ,must be injected directly through the injectors.
Heâs a mechanic - what else would you expect? He mentions âthe laws of physicsâ but clearly has no understanding of what they actually mean (other than knowing that when he removes the sump plug, the oil falls out). He mentions a âvolatile mixtureâ which is meaningless when talking about a substance (natural gas) which is a gas at normal temperature/pressure. He also appears to have difficulty with the concepts of igntion timing and efficient combustion in an internal combustion engine. Small wonder then that he cannot understand why a natural gas engine would be designed to work with direct injection of diesel fuel to initiate combustion. Hell, he even appears to think that a diesel engine emitting huge plumes of dirty smoke from every orifice and pre-igniting like a mad thing is running properly (Iâm sure weâve all experienced such âmechanicsâ over the years).
But yes - it is probably best to leave him to his fantasies while the grown-ups talk about other stuff.
Hey not all mechanics are bad, is there Any way of bringing LPG into this chat? Derv engines can run partially on that
The diesel/gas engines use fumigation to get the gas into the combustion chamber, it goes in through the inlet manifold along with the fresh air. BKing mentioning this as an example is actually proving his theory to be incorrect, as the oil from a failed turbocharger travels through the same path when it goes in to the engine
The diesel that is injected into the combustion chamber is only there to create pilot ignition as the dual fuel engines donât have spark plugs, so BKing⌠another epic FAIL
I thought he was referring to CNG engines as fitted in some MAN and Scania buses rather than the dual fuel jobs. In the case of the former there is absolutely no trace of diesel anywhere on the vehicle. As you say, epic fail (again) on his part.

That seems to be a recurring theme
To be fair I did have an argument here against everyone else concerning the limitations of compression ignition and when only spark ignition will really work properly.Itâs just that in that case I knew that I was right and everyone else was wrong.
A company called Hardstaff do a lot of the gas conversions ,along with their haulage side âŚI know they did the co-op fodens
Seems like AMOT, the makers of the Chalwyn valve, have been wasting their time selling an emergency engine shutdown valve, designed to prevent diesel engine runaway in the presence of inflammable vapours, since clearly the engine canât possibly run on anything that hasnât passed first through a fuel injector.
Are you by any chance a member of the Flat Earth Society?
