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
How much [zb] can you come up with? You need diesel to produce pilot âignitionâ with a gas but crappy old engine oil will just fire on its own.Just listen to your own crap man
Good lord, are you really that silly
Whilst the runaway engine is not an everyday occurrence, it is still a fairly common thing, however they donât just start up on their ownâŚ
An engine that suddenly starts running on oil from a blown turbo or intercooler full of oil, will of course already be running, so there will be diesel ignition to set the oil off, this will force the crankshaft to rotate, which in turn will, through gears or chains, make the camshaft turn, the lobes on the turning camshaft will open and close inlet and exhaust valves, allowing more oil to be forced into the cylinders from the open inlet valves and a combination of heat and compression will ignite the oil and let the gases escape through the exhaust valves which will open as part of the four stroke cycle, engine speed will be dictated by the amount of oil forced into the combustion chamber, at some point the crankshaft main or big end bearings will seize or the pistons/rings will break up due to lack of oil and this, in conjunction with the rotational forces applied to the crankshaft will make metal to metal contact resulting in loud clonking noises, then a large bang and then it will go quiet.
Honestly newmercman, me thinks you are wasting your time.He wonât take any notice ,and you wonât change his mindâŚIn short it is a lost cause.Save yourself before itâs too late

Oh and youâre welcomeâŚ
The issue of it being the diesel that started the process off is probably irrelevant anyway to Bkingâs understanding problems.Because itâs the ability of the oil to act as a fuel under compression ignition in itâs own right,having got into the cylinder by indirect means in the form of simple induction via the inlet manifold not the injectors,that he obviously canât ( more likely wonât because he doesnât want to admit heâs wrong ) get his head around.
However the obvious flaw in the LPG diesel pilot idea seems to be that,unlike oil or diesel,itâs still using a fuel which detonates not combusts under compression ignition type ratios.In which case the diesel pilot is a red herring because assuming the LPG and air mixture has been put into the cylinder in the same indirect way via the inlet manifold,before the diesel pilot is injected directly to ignite it under compression ignition,itâs obvious that youâll already have compressed that LPG and air mixture to the point where itâs likely to detonate not combust in order to fire the diesel pilot.The same would also apply even if the LPG had been injected directly into a cylinder subject to diesel compression ignition type pressures.Which probably explains why that example of an optimum LPG truck engine conversion involved not just using spark ignition but also reducing the compression ratio from diesel levels to that required for ignition and optimum combustion of a petrol based fuel.

A gas injected? How the â â â â do you inject a gas into a 500 bar environment!Its drawn in with the induction air you thick â â â â â â â â â me strength.

I think you need to get past infant school education first.In which case youâll then ( hopefully ) learn the four stroke cycle and the difference between cylinder pressures during the induction stroke as opposed to the compression stroke and then if you can understand that ( which I doubt ) theyâll then try to teach you the difference between indirect injection/fuel feed as opposed to direct.Although I think that anyone with any sense would realise that trying to teach you the basics of how an engine works is a total waste of time.
Its so sad you fail to see the irony in your comment.
No one needs to be an expert to see how a diesel engine can run away!
But I spose some need to be pretty bloody thick to discount too.
And also not admitting they are wrong after making complete dicks of themselves on an internet forum.
You really are bloody priceless chum!

Bking:a classic example of a man with a fork in world of soupâŚ
Well there you go you dont need to pump fuel at high pressure, or at the right time you just chuck oil down the inlet manifold without an air supply and âBANGâ your off like a rocket.
I think its just a ploy to sell timing belts,gears and injectors.
Just â â â â engine oil in and let the pistons do their own thing.You really dont even need diesel do you,after all the turbos [zb]ed so you dont even need air.
Bking:
Just â â â â engine oil in and let the pistons do their own thing.You really dont even need diesel
[zb] me I think heâs just got it !!!n
No he hasnât because he doesnât believe that a forced induction engine could still run on a naturally aspirated basis if the turbocharger stops turning.Nor that itâs possible to provide a combustible mixture of oil and air on an indirect fuelling basis via the inlet manifold and induction stroke.Nor that the resulting mixture will ignite under compression.So thereâs a long way to go yet.

Sorry dude I was being a sarcastic â â â again ,
What a berk on the bike. WTF was he going to do if he got to the air intake / venturi / airbox, stick his hand over it ? He was lucky he didnât get both of them an ambulance ride. Does B.King ride a motor bike I wonder.
