Pretty sure there was some years ago but with the growth of bio fuels, not sure what the reason would be.

Mazda already has their Skyactiv X on their road cars so it's not completely gone, its just that a lot of car companies doesn't give a damn about ICE at all recently.
 
I was talking about F1, which is what the thread is about rather than road cars.
 
The original point was making a diesel engine from am F1 engine. I know there was talk about it appearing in F1 but this went nowhere.

The other poster was talking about road cars, Outside the original topic.
 
OK, but it was not my point, that the Formula 1 might turn to Diesel engines by rules intenionally, but the current design of the gazoline engines is closer to a Diesel engine than to an Otto engine as we know it. The combustion chamber looks like a Diesel engine, the valves are almost parallel to the cylinder, the compression ratio is 18:1 peak pressure will be way above 200 bar, the engine runs lean and the combusion process is something in between a Diesel, Gazomine and CAI.
 
From 2006 until 2011, Diesel-engined cars won the 24 hours race of Le Mans in the LMP1 category. Peugeot won in 2009, Audi won the other five races. After that, hybrid cars ruled.
 
Yes I know, but nowaday we have Otto engines in Formula 1 which are designed very much like Diesel engines.

In Le Mans, the rules were changed in favour of the hybrid cars.
 
Merely pointing out that a Diesel racer is possible. In racing, changing rules can be a blessing or a curse.
 
Pardon me, this thread popped up in the sidebar of another discussion.

You mean, "after that, the rules were changed banning diesel engines" because diesel fuel has significantly more energy per kg than gasoline.
 
The different fuel contend was not the point, according to my knowledge there was the same amount of energy foreseen for gasoline vehicles.

Diesel-powered cars won every Le Mans 24 hours between 2006-2014, all of which by Audi with the exception of Peugeot in 2009. Diesel was not explicitly banned until the Hypercar rules package replaced LMP1 in 2021, although no LMP1 diesel cars were entered at Le Mans after Audi pulled out at the end of 2016.
 
With the introduction of air restrictors and balance of powers, there was no chance left for a Diesel powered car.

The Hypercar rules, that everyone has to built a mediocre car at the same level.
