Abstract
Gaseous and PM emissions of three Class 1 (sub-170cc) on-highway motorcycles from Thailand that were equipped with crankcase scavenged two-stroke engines were evaluated at the U.S. EPA-National Vehicle and Fuel Emission Laboratory (NVFEL). Very little data currently exists on PM emissions from two stroke motorcycles. There are a large number of two stroke motorcycles in Asia, which appear to be a considerable contributor to PM inventories. This testing was conducted in response to a request from the World Bank for assistance in determining emissions factors for motorcycles commonly used in Asia.
