Introduction
Close your eyes and picture a bike that can ride nearly 200 kilometers on only one litre of petrol. Sounds like a dream, right? Yet, this amazing idea is now becoming real thanks to the relentless dedication of one man.
Meet Shailendra Singh Gaur
Shailendra Singh Gaur, an alumnus of Allahabad University, has made headlines across India — and beyond — by inventing a six-stroke engine packed into a 100cc TVS bike that delivers a jaw-dropping fuel efficiency of 176 km per litre. That’s over three times more efficient than conventional engines!
From Enthusiast to Inventor: A 20-Year Journey
Shailendra Singh Gaur didn’t get to this breakthrough overnight. His journey spans nearly two decades of tireless experimentation and unwavering belief in his idea. Using his rented home in Jhunsi, a town near Prayagraj, as his lab, he devoted years to design and refine his invention — even selling his farm, shop, and house to keep the project rolling.
After graduating with a BSc (PCM) degree from Allahabad University in 1983, he briefly worked in labs at MNNIT under Prof. Anuj Jain and at IIT-BHU. But he turned down a job at Tata Motors in 2007, choosing instead to focus entirely on developing his innovation.
The Six-Stroke Engine: Breaking Boundaries
So what makes Shailendra’s engine different? Traditional engines use two strokes or four strokes, but his innovative design adds two more. The six-stroke mechanism lets the engine use energy more efficiently — estimating energy utilization at around 70%, compared to much lower levels in current engines.
Shailendra Singh Gaur successfully retrofitted this engine into a 2017-model, 100cc TVS bike. In a test, the bike ran continuously for 35 minutes on just 50 ml of petrol, which translated into 176 km per litre. As a comparison, the bike with the standard engine would last merely about 12.4 minutes. Additionally, he demonstrated it on television, where the bike reportedly ran 120 km on one litre of fuel.
Patent Recognitions
Shailendra’s invention hasn’t just made waves online — it’s also earned official recognition. He’s been granted two patents by the Indian government for his novel engine design, with more applications currently in the works.
Why It Matters
This innovation could be a game changer in multiple ways:
1. Exceptional Fuel Efficiency
A bike covering 176 km per litre of petrol would bring enormous savings for everyday commuters and long-distance riders alike.
2. Cleaner Air
The design drastically reduces harmful emissions like carbon monoxide and other pollutants. A six-stroke engine could help make future vehicles far kinder to the environment.
3. Versatility
Remarkably, the six-stroke engine can be adapted to nearly any fuel-powered vehicle — not just bikes, but cars, buses, trucks, and even boats.
4. Homegrown Innovation
This breakthrough shows that ground breaking inventions don’t always come from big labs or companies—sometimes, they emerge from a humble rented home driven by passion and grit.
Bringing the Invention to Life: The Road Ahead
Despite these exciting advances, Shailendra Singh Gaur still faces challenges. His work hasn’t yet reached mass production or partnered with any major automakers. He hopes industry players or government agencies will take interest and help scale the innovation so the public can benefit.
Putting It All Together: A Narrative You’ll Remember
1. The Problem
Fuel prices keep rising. Pollution chokes our cities. And yet, mileage improvements in conventional engines are slow.
2. The Solution
Shailendra Singh Gaur envisioned a world where one drop of petrol travels further — and cleaner. His six-stroke engine design achieves just that.
3. The Journey
His journey was lonely and uphill — from selling personal property to building his lab at home, every step demanded sacrifice.
4. The Breakthrough
A 100cc bike, retrofitted with the engine, traveled 176 km per litre. A feat that stunned experts and the public alike.
5. The Promise
This isn’t just a bike—it’s a possible blueprint for clean, efficient transportation across all vehicle types. It’s India-made innovation, ready to shine.
Imagine if your bike could travel 176 out of 200 kilometres on just 1 litre of petrol.
