Prayagraj's Shailendra singh gaur built a six stroke engine after the hardwork of 18 years. It delivers up to 200 km/l mileage with minimal pollution and can run on multiple fuels. I am sure that many powers want to finish him because history is the proof that if anyone wanted to change the world, his own world had finished. Save this man who can bring a revolution in automobile industry. Share this information to atleast 5 persons to spread awareness. It's Time To Change!!!!
