Two-stroke engines are used in motorcycles, three wheelers and "tuk tuk’s" throughout Asia and Africa for basic transportation. While powerful and reliable, they are a major source of air pollution. In the Philippines, 2-stroke engines are used to power 1.3 million three-wheeled "tricycles" which are used as taxis. The pollution from these tricycles contributes heavily to the 2000 premature deaths, 9000 cases of severe respiratory illness, and $430 million economic costs which occur each year as a result of poor air quality. Not only do these 2-stroke engines threaten public health in major cities, the pollution can inflict damage on historical and ecological sites. EnviroFit seeks to improve health by reducing 2-stroke emissions in Asia and Africa, thereby eliminating millions of tons of carbon monoxide, unburned hydrocarbons, particulates, and greenhouse gases.
