No car company would hire him for two years. Now, instead of building engines, he swept floors.
Isabel couldn’t help but be interested as Carlos looked at the prototype.
He said the problem wasn’t with the design but with the assembly. The two systems had been calibrated separately when they should have been beating together, like a single heart.
The engineers were shocked by how simple his reasoning was.
Isabel still made fun of him. Carlos said he needed twelve hours and promised that the engine would “sing like a Stradivarius.”
Isabel agreed to his terms after losing her patience and hurting her pride. She said again, “If you fix this engine that twelve engineers couldn’t, I’ll marry you.”
Carlos nodded. There was no noise in the room. The deal was done.
He would have twelve hours to prove himself with full supervision. If he didn’t do well, he would be banned for life.
Carlos worked all night because he wanted to get back his lost dignity.
Isabel and the engineers came back at dawn. There were a lot of notes, sketches, and tools all over the lab, but the engine looked brand new.
Carlos stood by his work, tired but glowing.
As he looked over the recalibrations, Herrera, the lead engineer, whispered in disbelief. Carlos used aeronautical algorithms to sync the hybrid systems, which made the parts work together.
The engine started up smoothly when Isabel pressed the ignition. There were no rattles or vibrations, and it sounded like music.

The janitor did in twelve hours what twelve engineers couldn’t do in six months, saving the company and a €500 million deal.
But Isabel’s promise weighed heavily in the air.
