A fact from this article was featured on Wikipedia's Main Page in the On this day section on February 23, 2005, February 23, 2006, February 17, 2022, and February 17, 2023.

I've been using Google's Gemini 2.5 Pro Experimental large language model to create summaries for the most popular articles with {{Technical}} templates. This article, Diesel engine, has such a template in the "Thermodynamic cycle" section. Here is the paragraph summary at grade 5 reading level which Gemini 2.5 Pro suggested for that section:

A diesel engine works differently than a gas engine because it doesn't need a spark plug. First, it takes in only air. Then, it squeezes the air really hard, which makes the air get super hot. Next, the engine sprays fuel into this very hot air. The heat of the air makes the fuel catch fire all by itself. This burning pushes down a part called a piston, which creates power to make the engine run. Squeezing the air so much helps the engine use fuel very well.

While I have read and may have made some modifications to that summary, I am not going to add it to the section because I want other editors to review, revise if appropriate, and add it instead. This is an experiment with a few dozen articles initially to see how these suggestions are received, and after a week or two, I will decide how to proceed. Thank you for your consideration.

I am retracting this and the other LLM-generated suggestions due to clear negative consensus at the Village Pump. I will be posting a thorough postmortem report in mid-April to the source code release page. Thanks to all who commented on the suggestions both negatively and positively, and especially to those editors who have manually addressed the overly technical cleanup issue on six, so far, of the 68 articles where suggestions were posted.
