At the moment, the cars require energy management techniques such as recovering energy while on full throttle, which leads to a speed drop-off before corners and through some fast curves.
The expectation is that the change will almost entirely eliminate this other than at the most energy-starved circuits.
A statement from the FIA said the meeting had agreed unanimously on the changes.
The details will be discussed in technical groups involving teams and power-unit manufacturers before a final package is agreed.
These groups will also discuss other measures that could be adopted towards achieving the same aim.
The changes will require development to existing engines but a senior insider said: “Everybody is in the mood for a challenge.”
There are technical constraints that need to be resolved, for example that some teams want to carry over the chassis into 2027 to reduce cost, so increasing the size of their fuel tanks would be difficult.
The meeting also echoed the F1 drivers’ views that changes to the operation of the engines for last weekend’s race in Miami had been “a step in the right direction”.
The drivers almost unanimously expressed the same view over the weekend in Miami.
McLaren’s world champion Lando Norris said after finishing second in the race on Sunday: “It’s a small step in the right direction, but it’s not to the level that Formula 1 should still be at yet.
“If you go flat out everywhere and you try pushing like you were in previous years, you still just get penalised for it. You still can’t be flat out everywhere. It’s not about being on as early on throttle everywhere.
“You should never get penalised for that kind of thing and you still do.”
