Is paraffin the same as diesel?

Who commented on that?
Stu
PS
Read this, http://www.jcmmachine.com/detonation_preignition.htm quite definite about pre ignition and detonation occurring together

Yup and lemmings all jump off a cliff together.... Dosen't mean thet are right though does it? And no, I haven't watched it, I don't need to, years of building and tuning race engines, winning ones I might add, running 30 psi pressure on methanol have taught me all I need to know about both...... And yes they can occur almost at the same time, but one always follows the other and pre ignition under load ALWAYS kills engines.

I also have a 1.8 Ford diesel engine rig which during training I have often primed and tried to start on petrol..... It doesn't...... Untill you add some heat from the glow plugs.......

Now I have had enough of your stupid argument. Believe what you want, I really don't care & can't be bothered!
 
The running on is caused by something glowing hot in the combustion chamber, thats how glow plug engines in model aircraft work, an electric glow pin to start it and then the pin is disconnected from the battery BUT continues to glow from the heat of the combustion.
In the olden days the need to decoke every year was driven by the build up of carbon from the less sophisticated lube oils and fuels and the relatively poor control of the mix of fuel and air.
The hot spot can also be a piece of a rough head casting

So the advise I was given at the time was correct, my Rover 2000 sc probably did need a decoke.

I will say it one more time:
All internal combustion engines are "gas" burning engines.
All engines will burn hydro carbons if that hydro carbon can be converted to gas.
So:
Petrol engines run on petrol converted to "gas" by the carb or injectors.
Diesel engines run on fuel oil converted to "gas" by the injection system.
Both engines will run on "pure" gas if it is introduced in to the intake system, they will not run very well and will probably be damaged if it is introduced in an uncontrolled manner.
Diesel engines will run on any fuel oil that can be introduced through the injection system and that includes petrol, kerosene, paraffin, jet A1, lube oil, peanut oil, butter, margarine etc etc. What it does when the heat of compression ignites the fuel is another matter!
Light fuels, such as gas or petrol, burn in an uncontrolled manner when introduced to a diesel and cause damage because of that. If the timing is adjusted and the method of introducing it is adjusted AND if a method of lubing the injection equipment is provided then a diesel engine will happily run on any hydro carbon. Indeed the shipping pumps that we used to use to pump crude to offshore tankers were designed to start on diesel fuel and then when warmed and running smoothly, were switched to a supply of natural gas that we took from the crude we were shipping.
These are facts, they are not something I made up, pointing them out does not warrant you calling me a ****.

You have managed to dig an extremely deep hole for yourself, may I humbly suggest that you stop digging NOW. The offensive manner in which you called another forumite a rather rude name, will not do you any favours, totally unjustified!

This from the guy who writes such PC things as:

Wots a pikkie, is it the same as gypo scum?
:rolleyes:

Who made you a mod anyway?
 
A lighter bit of Fred Drift:-

I remember my being with Dad and Mam during WW2, returning from a long trip on his motor cycle combination, running out of his miniscule ration of petrol and ending the journey with a tank full of paraffin; obviously another decoke due.

I think there is a difference between posting in the lounge, where banter is expected, than posting on Scuttlebutt.
Foul language can be read on Scuttlebutt by young children. you have to be a member to use the lounge.
If however you think it ok to use four letter abuse on Scuttlebtt, then our morals differ, sorry.
 
My Dad was in the REME during the war working on tank engines.

I think that these were/are diesel engines and he used to tell me that they could run on anything combustible as fuel supply was unreliable at the front - he reckoned that they tried engine oil, cooking oil, kerosene, paraffin, anything and I'm sure they must have also tried various grades of petrol

Onviously these were not modern engines and probably not even standard diesels for the 1940's but, if I'm right, this would seem to suggest that, in principle, a spark is not required for ignition.

Jerry used to refer to our tanks as 'Tommy Cookers' because of the ease with which they caught fire - petrol certainly. The E boats were far superior to our MTBs because they were diesel. With their Chrysler engines the MTBs were floating bombs.

We do indeed differ, I tend not to be hypocritical and pompous! ;)
