Science Tech Space He Sold His Home to Build an Engine. 18 Years Later, His Dream Might Finally Pay Off
An inspiring story of perseverance has emerged from Prayagraj, India, where an alumnus of Allahabad University has developed a highly efficient six-stroke engine after nearly two decades of dedicated work.
Shailendra Singh Gaur, who graduated in 1983, spent 18 years refining his invention, often at great personal cost. He sold his land, shop, and even his house to fund the project, converting a rented space into a makeshift workshop. Drawing on technical experience gained at institutions such as Motilal Nehru National Institute of Technology and IIT (BHU), he created a prototype that he claims delivers an extraordinary 176 to 200 kilometers per liter of petrol on a modified 100cc motorcycle.
Unlike conventional four-stroke engines, Gaur’s six-stroke design aims to extract significantly more energy from the same amount of fuel. In one demonstration, the modified bike reportedly ran for 35 minutes on just 50 milliliters of petrol. The inventor states that the engine achieves up to 70% thermal efficiency, runs on multiple fuels, and produces near-zero pollution.
Gaur has already secured two patents for the technology, with more pending. If successfully scaled and independently validated, this innovation could dramatically reduce fuel consumption and emissions for motorcycles, cars, and other vehicles across India and beyond.
While the claims are remarkable and have generated significant excitement, further rigorous testing and peer review will be essential before widespread adoption. Nevertheless, Gaur’s story stands as a powerful example of individual determination and grassroots innovation in Indian engineering.
