In the vast history of inventions, every once in a while, a breakthrough emerges that has the potential to change the course of human progress. Engines have been at the heart of human mobility for more than a century, fueling cars, trucks, airplanes, and even ships. Yet, engines have also been one of the largest contributors to pollution and global warming. Amidst the rising concerns of climate change, fuel dependency, and environmental degradation, the story of an Indian inventor from Prayagraj, Shailendra Gaur, stands out as a beacon of hope.
After 18 years of relentless research, experimentation, and perseverance, Shailendra Gaur created a Six-Stroke Engine that is being hailed as a marvel in engineering. This engine promises a mileage of 176–200 kilometers per liter of petrol, can run on multiple types of fuel, and produces nearly zero pollution. If implemented on a large scale, it could mark the beginning of a new era in the automobile industry and environmental conservation.
The Long Journey of an Inventor
Inventions do not happen overnight. Behind every innovation lies a story of sacrifice, failures, and determination. Shailendra Gaur’s journey is no different. Hailing from Prayagraj, a city known for its rich history and culture, he dedicated almost two decades of his life to solving one of the world’s biggest problems: how to make engines more efficient and less harmful to the environment.
Most people give up when they face repeated failures, but Gaur was different. He believed that hard work and consistency could change the world. Over the years, he kept experimenting with engine designs, studying the limitations of existing four-stroke engines, and identifying ways to overcome those drawbacks. His ultimate goal was simple yet revolutionary: an engine that could save fuel, reduce pollution, and work with versatility.
Understanding the Six-Stroke Engine
- Intake Stroke: The piston moves down, drawing in a fuel-air mixture.
- Compression Stroke: The piston moves up, compressing the mixture.
- Power Stroke: The spark plug ignites the mixture, causing a combustion that forces the piston down. This is the first power stroke.
- Exhaust Stroke: The piston moves up, pushing out the combustion gases.
- Water Injection/Steam Power Stroke: A small amount of water is injected into the hot cylinder. The residual heat instantly vaporizes the water into steam, which expands rapidly and forces the piston down again. This is the second power stroke.
- Steam Exhaust Stroke: The piston moves up, expelling the steam from the cylinder, preparing the engine for the next cycle.
To appreciate Gaur’s achievement, it is important to understand what makes a six-stroke engine different from the traditional engines we use today.

The Conventional Four-Stroke Engine
Most vehicles in the world run on a four-stroke engine, which consists of the following stages:
- Intake Stroke – Fuel and air enter the cylinder.
- Compression Stroke – The mixture is compressed.
- Power Stroke – The fuel burns, pushing the piston.
- Exhaust Stroke – The burnt gases are released.
While efficient, this system wastes a lot of heat energy, consumes significant fuel, and produces harmful emissions.
The Six-Stroke Engine
In Gaur’s design, two additional strokes are introduced, which utilize the otherwise wasted heat and gases. This allows the engine to extract more energy from the same amount of fuel. As a result:
- Fuel consumption is drastically reduced.
- Heat is better managed, leading to less wear and tear.
- Pollution levels drop to nearly zero because of more complete combustion.
- This innovation bridges the gap between performance and sustainability.
- Fuel Efficiency: 176–200 Km Per Liter
Perhaps the most astonishing claim of Shailendra Gaur’s six-stroke engine is its extraordinary mileage. With traditional engines, even the most fuel-efficient motorcycles offer 60–80 kilometers per liter, while cars offer much less. In contrast, Gaur’s engine offers 176–200 kilometers per liter, which is nearly three times more efficient than the best-performing vehicles today.
The implications of this are massive:
- A commuter could travel from Delhi to Jaipur on just one liter of petrol.
- Families would save thousands of rupees annually on fuel costs.
- Nations could reduce their dependency on crude oil imports, saving billions of dollars.
- Multi-Fuel Capability
Another standout feature of this engine is its multi-fuel compatibility. While traditional engines are designed to run on a single type of fuel, Gaur’s six-stroke engine can run on petrol, diesel, kerosene, ethanol, and even biofuels.
This flexibility is a game-changer:
- It reduces dependency on a single energy source.
- It encourages the use of eco-friendly alternatives like biofuels.
It makes the engine suitable for diverse regions, especially rural areas where petrol may not always be available.
This adaptability not only makes the engine more versatile but also future-proofs it against fuel crises.
Almost Zero Pollution
One of the most pressing issues of our time is air pollution. Cities around the world, especially in countries like India, struggle with smog, respiratory diseases, and poor air quality caused largely by vehicular emissions.
The six-stroke engine addresses this issue head-on. Because it utilizes fuel more efficiently and reduces incomplete combustion, the emissions produced are minimal to nearly zero. This means fewer greenhouse gases like carbon dioxide, less carbon monoxide, and fewer unburnt hydrocarbons.
If adopted widely, this technology could significantly:
- Reduce urban air pollution.
- Slow down the pace of global warming.
- Improve public health and lower medical costs associated with pollution-related illnesses.
- Challenges Faced by Innovators
While Shailendra Gaur’s invention sounds revolutionary, it is important to recognize the struggles faced by independent innovators in countries like India. Despite creating something that could potentially change the world, inventors often face challenges such as:
Lack of financial support –
Years of research require investment, but funding is often scarce.
Limited recognition – Media and government bodies may overlook individual inventors.
Resistance from established industries – Large corporations benefiting from existing technology may not welcome disruptive inventions.
Yet, Gaur’s story shows the importance of persistence and vision. Against all odds, he continued working, motivated by the desire to contribute to society and the environment.
Potential Impact on the Automobile Industry
If commercialized, the six-stroke engine could transform the automobile industry in the following ways:
- Revolutionizing Mileage Standards
Vehicles could travel longer distances with minimal fuel consumption, setting new benchmarks for efficiency. - Boosting Electric-Hybrid Technology
The engine’s efficiency could be combined with hybrid systems, creating super-efficient vehicles that blend fuel and electric power. - Reducing Oil Dependency
Countries heavily reliant on oil imports could become more self-sufficient, reshaping global geopolitics. - Affordable Mobility
With reduced fuel costs, transportation would become cheaper for everyone, from families to businesses.
Environmental Significance
The invention aligns with global efforts to combat climate change and reduce carbon footprints. Governments around the world are spending billions to push electric vehicles (EVs), but the transition is slow due to infrastructure challenges.
In the meantime, a six-stroke multi-fuel engine could serve as an immediate and highly effective solution. It reduces pollution without requiring massive infrastructure overhauls, making it a practical alternative to bridge the gap between traditional engines and full electrification.
A Call for Support
Innovations like Shailendra Gaur’s six-stroke engine need encouragement and support. Governments, research institutions, and automobile companies must step forward to:
Provide funding for large-scale testing and development.
Offer recognition and patents to protect the inventor’s rights.
Explore partnerships for commercial production.
Such support could ensure that this invention reaches the global stage and benefits millions of people.
Conclusion
The story of Shailendra Gaur from Prayagraj is not just about an engine—it is about the power of human determination and innovation. After 18 years of hard work, he has gifted the world an invention that could redefine mobility, reduce pollution, and save energy for future generations.
In a world where climate change and energy crises are threatening our very survival, Gaur’s six-stroke engine is more than just a mechanical innovation—it is a symbol of hope. It reminds us that one individual’s vision and perseverance can indeed change the world.
If adopted widely, this invention could make fuel scarcity a problem of the past and pave the way for a cleaner, greener planet.
