I have made two IC engines which has not been achieved in past.1> valves operated 2 stroke engine, solving the lubrication and white smoke emission porblem.scavenging process is the most efficient till date.2> switchable 2 stroke and 4 stroke cycle in one engine.I am looking forward to collaborate with like minded individuals, startups, coorporates and univeristies to take this forward together and convert it into an universal product. Drop a message if this interest you, thanks!
