Maybe a stupid question, can you get a diesel to pop through the exhaust like a petrol?
It's not that i'm wanting to i'm just wondering
Cheers

i dont think so as diesel is not as explosive as petrol?
someone will correct me if im wrong..
would be cool though

Might do if using millers though tbh I have never heard mine do it.
Had a new cambelt? Timing could be out a little.

Going from how a petrol "pops"
I think it's petrol vapour that ignites causing the pop when the exhaust is hot enough.
I don't see why a diesel couldn't do the same, the conditions just need to be right...
this is a guess though...

a diesel will NEVER pop....
Simple fact is diesel is not flammable - well, it "is", but it isn't. Coming from someone who tried to start a fire with a gallon of the stuff and it still barely burned. Diesel's combustion comes from compression, and this cannot happen in an exhaust. I have plenty of spare fuel coming out the exhaust - that's what the black smoke is. But it will never explode in the exhaust due to it not being even close to as flammable as petrol. I also believe derv exhausts don't run as hot as petrol ones. Could be wrong though.
remember that petrol is a liquid trying to be a gas, and diesel is just oil....

Very well explained mate, cheers.
Just something thats been cleared up for me and interesting to know.

Thats will be it hitting the limiter then

got a video of this? would be a laugh to watch
I also think ( could be wrong) that diesel needs to be under compression to ignite - this isn't going to happen in the exhaust for obvious reasons.
In any normal circumstance you don't get unburned fuel coming through a diesel engine and getting into the exhaust. Diesels are controlled by varying the injection quantity into a full charge of air, the more air the better, so they are almost always running lean. As revs rise, the engine is limited by the fact that diesel burns more slowly than petrol, and you get to a point where it can't all burn before the piston starts pushing it out. The part-burned fuel comes out as soot, I don't think you ever get to the point where diesel vapour is carried through completely unburned.
I'd not expect a modern petrol car to have fuel detonating in the exhaust, because the catalyst should stop it.

was years ago and I was VERY drunk so thought it was a good idea!
how can you tell if your driving?
and for flames...? as said above, diesel needs to be compressed to ignite.
