Alexandre Zuquete Guarato

Engineering

In the era of electric vehicles, the question arises: why do we stick to combustion engines? This is precisely the question that drives mechanical engineer Alexandre Zuquete Guarato’s research. He holds a Ph.D. in mechanical engineering from the École Normale Supérieure Paris-Saclay, which he earned in collaboration with Renault, and completed his post-doctoral studies at Pontifical Catholic University of Rio de Janeiro (PUC-Rio).

Alexandre is developing a flex-fuel rotary engine with a variable compression ratio to enhance its efficiency. His career in mechanical engineering was inspired by his father, who worked as an engine rectifier until his retirement. Alexandre is married to a psychologist, and they share their home with their two dogs, Pixel and Oliver. During his downtime, Alexandre enjoys cooking and practicing yoga.

Revolutionizing Rotary Engines: A flex-fuel powerhouse with variable compression ratio
Science / Engineering

Modern internal combustion engines essentially maintain the same configuration as the original engine invented by Nicolaus Otto in 1876. The advancements introduced by automakers in recent decades primarily revolve around adding peripheral systems. Moreover, flex-fuel engines, prevalent in Brazil, operate with a fixed compression ratio that is suboptimal for either gasoline or ethanol. As a result, a significant portion of the energy contained in these fuels is squandered every day. This project seeks to develop an innovative rotary engine with a variable compression ratio, facilitating optimal combustion conditions for any blend of gasoline and ethanol. Owing to its novel configuration, it promises to be more compact, efficient, environmentally friendly, and potentially more cost-effective than existing engines.
