CEI develops, commercializes and sells clean engine technologies. Our first product is a fuel injection, LPG retrofit kit for 2 and 4 stroke motorcycle engines, focusing on the millions of such engines used to power commercial motorcycle taxis - tuk-tuks. There are millions of such vehicles in Asia, each polluting as much as 50 cars. Our effective, durable, affordable kit doubles drivers' income, while reducing tailpipe pollution by over 80%.
