MILLERS DIESEL POWER ECO MAX

[Bellow]

Well, this is certainly an unorthodox view........

It isn't. Reducing heat loss from the diesel combustion chamber is a goal decades old. Ditto the understanding that carbon adds thermal insulation.

This is the first entry on Google search (plenty more below it...):

"Carbon build-up is natural in any combustion engine – diesel or petrol. But, over time, this sooty material can thicken and put your engine at risk, causing that infamous dark smoke diesel engines are known to produce."
...
"Over time, this carbon build-up can cause all sorts of problems.... If left untreated, carbon build-up can eventually lead to engine failure."

As I pointed out before, I am not a qualified mechanic, I just go with what Mr Google says.

Google failed you.
The only sentence worth printing in the entire piece is the one advocating 'quality' oil. The rest is sentence after sentence of vagueness verging on the vacuous. Banging on about 'failure' but not once explaining the mechanism. The truth is, the carbon vulnerability is in the top ring where if the temperature exceeds the limit of heat the oil in use can withstand before carbonising then carbon will form and impede on the ring's ability to seal and thus fail. The two controlling factors are the oxidation stability of the oil and the depth of the first land shielding the top ring from combustion heat. And SFA to do with cleanliness of the piston crown which, lacking an insulating layer will be more inclined to absorb combustion heat and it transfer to the ring belt - promoting - not diminishing - potential carbonisation of oil there.

Your disagreement isn't with me.... the other Google links all say essentially the same essentially.... that carbon deposits are bad for Diesel engines.

Looked at it again and not far in there's this:

'' It’s the unburned fuel that sticks to surfaces inside the engine, like the pistons and cylinder walls.''

Carbon an a cylinder wall??? Aye, right. The rest of the article is no better.
If anyone wants to understand engines read the technical papers from properly conducted research - not repeated hearsay which in time will with AI be all that's available masquerading as knowledge but as useful as a chocolate tampon.

On the top section if the cylinder wall above the top ring?....seen it often....on dervs and two stroke bikes. Carbon is not good for any engine...apart from the stuff it runs on!...Ever seen a tuning shop rebuild an engine and leave the carbon to take advantage of it!?....me neither.

How does that cause the engine failure the article claims?
And, how does diesel contact the cylinder wall (as the article claims) when it burns at the injector and, enormous R&D with CFD conducted with staggering computing power is expended precisely to entrain the incoming fuel with air with wall impingement forbidden?
