Today, I.C. Engine tech is saturating at peak efficiencies from incremental refinement over a century. It is unable to deal with environmental market drivers of 21st century. Light transport is shifting to EV and this is driving demand for standalone, domestic and vehicle mounted ‘Green power generating units’ (for charging and range-extenders/ hybrid drive applications). Heavy transport is exploring green fuel as a clean alternative. However, despite century long pursuit by global majors, ‘VCR technology’ based ‘Green Fuel engines’, using LPG/ Hydrogen etc., remain unviable for extreme complexities in conventional (Slider Crank.) mechanism. We, KGYAT UK, offer you the RVCR - ‘Rotary Variable Compression Ratio’- innovation, a Deep-Tech endeavor in Prime-mover mechanism for transport and energy industry applications. It is based on invention patented in EU, UK, USA & China, (India Pending) in ‘Mechanisms of Energy Conversion’. Our RVCR I.C. Engine tech is at TRL5 and selected by European Innovation Council (SME-Inst-Ph-I) and RVCR, with its superior physics, combines advantages of VCR and ‘Direct Torque Transfer’ of conventional rotary mechanism, to deliver multi-fold increase in efficiency. The downsizing and reduced material results in high power to weight ratio with low capital cost. Low friction & low vibrations reduce operational costs. The RVCR salient gains among many are: - o Wide range VCR, allowing multi fuel flexibility (enabling end user to switch fuel in real time depending on availability, cost, and emission compliance needs). o Large torque at low speeds, reducing losses for high performance and long combustion residence time for clean burn to minimize noxious emissions. While global Industry is further moving towards incremental innovations, KGYAT offers RVCR, a Deep tech Game changer innovation to OEM’s, for gaining technological leadership and dominating 21st century global market with world 1st ever fuel agnostic I.C. Engine technology.
