I do not know if this question is outside the realm of the FSE. If this is so I will erase it. I am trying to understand why Google cannot give a proper translation of the following sentence:
How much work does it do, how much heat is discarded and what is the efficiency of the engine?
Combien de temps cela fait-il (!), combien de chaleur est rejetée et quelle est l'efficacité du moteur ?
For comparison DeepL works very well here :
Quelle est la quantité de travail, quelle est la quantité de chaleur rejetée et quel est le rendement du moteur ?
I tried several (free) online translating services of various sorts and I have not seen the like of Google's strange behavior (translator). Any ideas ?
