Respuesta :
i think the discovery that carnot made that helped him recognize how to crete the 'perfect' heat engine was  : The difference in the temperatures between hot and cold reservoirs determine how well a heat engine would work.
Here are the formula of Carnot's efficiency : Â 1 - Tc / Th
Tc  = Cold reservoir
Th = Hot reservoir
hope this helps

Answer:
Explanation:
His notion that the efficiency of an idealized engine depends only on the hottest and lowest part ( source and sink ) and not on the working substances like steam etc, led him to think about coming up with a hypothetical heat engine having 100 percent efficiency.
