Rotary VCR I C Engine tech

Absolute Variable Compression Control.

An adaptive, fuel-flexible, Smart Combustion, high-efficiency engine tech based on ‘RVCR’ mechanism – for the clean mobility era.

The Challenge with Conventional Engines

Traditional IC engines, even with a century of refinements, are inherently limited by fixed compression ratios and rigid crankshaft dynamics. This compromises fuel efficiency, emissions, and adaptability — especially in hybrid systems and variable load operations.

With the global push for decarbonization, current engine architectures struggle to meet the dual mandate of performance and emissions compliance.
