About Us
Isochor Engines™ is a purpose-driven company pioneering breakthrough thermodynamic technology to enable clean, efficient and accessible power.
Explore our story and the core values that drive our mission to decarbonize how the world converts fuel into energy.
Who We Are
Isochor Engines™ is a pioneering early-stage startup based in Delaware, developing breakthrough thermodynamic technology that redefines how fuels are converted into power.
Our mission is to make clean, efficient energy both technically achievable and broadly accessible—without environmental compromise.
Unlike conventional internal combustion or turbine systems, Isochor Engines™ applies pressure-gain and constant-volume principles to achieve step-change improvements in efficiency, simplicity, and scalability.
This approach enables compact, multi-fuel generators that operate on renewable fuels such as hydrogen, e-methane, and synthetic e-fuels—ideal for off-grid power, clean backup generation, and hard-to-electrify sectors.
As a founder-led company, Isochor Engines™ blends engineering innovation with environmental purpose, advancing a platform that supports the global transition to a resilient, low-carbon energy future.
Isochor Engines™ isn’t just reimagining engines—it’s reimagining energy conversion for a cleaner, smarter world.

Our Story
Isochor Engines™ 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 advancing thermodynamic 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 energy conversion system. Though he passed away before seeing his vision realized, he inspired his daughter, Dr. Emilia Apostol, to carry the torch forward. With a Ph.D. in electrical engineering and expertise in complex system design, Emilia advanced the research, achieving a breakthrough architecture for a compact, ultra-efficient power platform capable of operating on renewable fuels such as green hydrogen.
Today, Isochor Engines™ continues that legacy—combining deep technical roots with a mission to deliver sustainable, scalable clean-energy solutions for a decarbonized future. Every step we take honors the innovation and perseverance that brought us here.
