Our Story
IsochorEngines™ was born from a decades-long pursuit of innovation—rooted in a vision first sparked in the early 1990s. It began with engineer Vitzu Mălureanu, who recognized that combustion engine efficiency could play a vital role in addressing climate change. Long before the energy transition became a global priority, he dedicated his life to rethinking how engines work—believing that greater mechanical efficiency could reduce emissions and redefine sustainability.
Driven by this conviction, Mr. Mălureanu devoted years to designing a new type of engine. Though he passed away before seeing his vision realized, he inspired his daughter, Dr. Emilia Apostol, to carry the torch forward. With a PhD in electrical engineering and expertise in complex system design, Emilia advanced the research, eventually achieving a breakthrough architecture for a compact, ultra-efficient engine powered by renewable fuels like green hydrogen.
Today, IsochorEngines™ continues that legacy—combining deep technical roots with a mission to enable sustainable, scalable energy solutions for a cleaner future. Every step we take honors the innovation and perseverance that brought us here.
