Talk:Diesel fuel

Fatty acids

This sentence is misleading:"Biodiesel is obtained from vegetable oil or animal fats (biolipids) which are mainly fatty acid methyl esters (FAME), and transesterified with methanol." Biolipids are esters of propan-tri-ol (glycerine) and fatty acids, not methyl esters. They become FAME through transesterification. 153.100.134.67 (talk) 14:08, 16 January 2024 (UTC)

"Otto" engine

it would be useful to link to Otto engine to clarify. 142.163.195.114 (talk) 14:48, 15 March 2024 (UTC)

"1911 World's Fair in Paris" possible falsehood

In the section Diesel fuel#Origins it mentions the "1911 World's Fair in Paris" which is mentioned in the source on Google Books, but a quick google search seems to show that there never existed a 1911 World's Fair in Paris. HertzDonuts (talk) 19:39, 14 August 2025 (UTC)

CO2 release paragraphs potentially misleading

Does anyone else think the paragraphs comparing estimates of the amount of CO2 released by burning one litre of diesel and petrol are

a) not relevant to the objectives of this page (or at least the relevance is not explained in the current text);

b) that the comparison is fundamentally misleading since the objective of burning the fuel is to do work so the comparison should be amount of CO2 released per unit of work done?

I suggest either removing these paragraphs, or adding an explanation of its importance important and changing the basis of comparison to be kg of CO2 per J or MJ. Nick the engineer (talk) 23:13, 13 February 2026 (UTC)

Ps. There are other issues I have with the Carbon Dioxde Formation section.

There are several key statements given without any reference, eg. the composition of diesel and petrol.

The stated compositions do not match the actual typical compositiona given in the subsection on Chemical Composition. Nick the engineer (talk) 23:28, 13 February 2026 (UTC)

Dead link in reference 38 — replacement available (MK-1 ULSD aromatics)

Reference 38 in this article is a permanent dead link:

This is cited in the sentence: "In Sweden, a diesel fuel designated as MK-1 (class 1 environmental diesel) is also being sold. This is a ULSD that has a lower aromatics content, with a limit of 5%."

A working replacement covering ULSD specifications, MK-1 diesel, and aromatics content in the context of diesel fuel quality is available at:

<<link redacted>>

The page includes a comparison table of EU EN 590 vs. Swedish MK-1 specifications including the 5% aromatics limit, polycyclic aromatic content, and sulphur thresholds, in the section titled "ULSD, MK-1 Diesel and Aromatics: Why Fuel Quality Directly Affects DPF Life."
