Introduction
Innovation often comes from unexpected places, and Prayagraj has given India one such story of determination and brilliance. Meet Shailendra Singh Gaur, an independent inventor who has spent nearly two decades building a revolutionary six-stroke engine that delivers up to 176 kilometers per litre (KMPL). His journey is not just about technology—it’s about sacrifice, perseverance, and a vision for a sustainable future.
A Journey of Sacrifice and Innovation
Shailendra Singh Gaur completed his B.Sc. in Physics, Chemistry, and Mathematics from Allahabad University in 1983. In 2007, he turned down a secure job offer from Tata Motors to dedicate himself fully to research. Unlike many who pursue innovation with institutional support, Gaur chose to work independently, often facing financial and personal hardships.
To keep his dream alive, he sold his land, house, and shop, even converting his rented accommodation into a makeshift laboratory. His relentless pursuit of knowledge led him to work under professors at MNNIT Prayagraj and IIT-BHU, where he refined his design and concepts.
The Six-Stroke Engine: What Makes It Revolutionary
Traditional four-stroke engines convert only about 30% of fuel energy into motion, with the rest wasted as heat and exhaust. Gaur’s six-stroke design introduces two additional strokes that maximize energy utilization, boosting efficiency to nearly 70%.
Key innovations include:
- Altering the piston thrust angle from 25° (in conventional engines) to 60°, extracting more power from the same fuel.
- Reducing carbon emissions to almost negligible levels.
- A flexible design that can work across multiple fuel types.
His invention has been granted two Indian patents, strengthening its credibility and protecting his intellectual property.
Real-World Testing & Performance
To prove the practicality of his design, Gaur modified a 2017 TVS 100cc motorcycle with his six-stroke engine. During testing, the bike ran for 35 minutes on just 50 ml of petrol, translating to about 176 KMPL. In a separate demonstration, the bike successfully covered 120 km on just one litre of fuel.
These results are far beyond the capabilities of conventional engines, which typically deliver 60–75 KMPL at best.
Why It Matters: Efficiency, Sustainability & Beyond
Gaur’s invention holds the potential to revolutionize the global automotive industry.
- Fuel Efficiency: Tripling the mileage compared to traditional engines.
- Environmental Benefits: Significantly lower carbon emissions and almost zero carbon monoxide release.
- Scalability: The six-stroke engine can be adapted for motorcycles, cars, buses, trucks, and even ships.
If commercialized, this innovation could drastically reduce fuel consumption, lower dependence on fossil fuels, and make transportation more eco-friendly.
Looking Ahead: Challenges & Opportunities
Despite the breakthrough, Gaur faces challenges in scaling up his innovation. Building prototypes and conducting further research requires funding, technical resources, and industry collaboration. He is actively seeking partnerships with automotive manufacturers, investors, and government agencies to bring his engine to the mass market.
With the right support, his six-stroke engine could become a game-changer for India and the world, offering a sustainable solution to rising fuel prices and environmental concerns.
