What is VC - Roto engine ?

The World’s 1st ever Fuel agnostic I.C. Engine

Conventional engines chug towards peak efficiency, struggling with fuel flexibility and emissions. VCR: a tech prodigy promising 30% fuel savings, multi-fuel mastery, and cleaner skies. Yet, it remains unrealized, strangled by clunky designs. But hope ignites with VC Roto Engine – a compact, super-efficient and green solution poised to finally deliver on VCR’s potential. 

Brace yourself for the revolution – sustainable power is closer than you think.


The Concept Technology

RVCR is based on a novel concept invention in ‘Mechanisms of Energy-Conversion’. RVCR mechanism based I.C.Engine (I.C.E) allows the long pursued ‘Variable Compression Ratio’ (VCR) feature, key to multi-fuel adaptability (switching from fossil to green-fuels during operation) with ease. This permits for smooth transition from fossil fuel use to green-fuels.
