I bought a 1975 Yamaha RS100 2-stroke road bike, and EnviroFit Corporation is installing a direct injection kit on it. Envirofit is sponsored by Colorado State University. Orbital Corporation of Australia invented a direct-injection technology that makes 2-stroke engines cleaner than 4-strokes. The 2-strokes are cheaper, more powerful, and are easier to maintain. EnviroFit designed a kit using Orbital technology, and has begun a humanitarian project in the Philippines to convert 2-stroke taxis (motorcycles with a big passenger sidecar with a roof) to direct injection. Not a big deal? There are 1,300,000 of these 2-strokes in use in the Philippines. The air pollution they cause results in thousands of premature deaths and much sickness. There are many millions more of the polluting 2-strokes in India, China and throughout Asia. After the Philippines program, EnviroFit plans to expand the project to convert 2-strokes in other countries. Converting them to direct injection increases fuel efficiency by about 30%. When you talk about many millions of vehicles, cutting gasoline usage by 30% is a huge deal that will have a big impact on what we pay at the gas station. In 2-strokes, the fuel intake ports and exhaust ports are briefly open at the same time, so unburned fuel escapes out the exhaust pipe. The patented Orbital system delays injection of the gasoline until both ports are closed. It also allows use of higher compression ratios, which results in more power. I´m going to ride the bike around the country, showing it to TV stations and newspapers, to get publicity for the EnviroFit organization.
