This paper develops the emission models of in-use motorcycles fueled by gasoline, E5 and E10 based on modal emission values which are collected from measurements on chassis dynamometer based on standard driving cycles. | Journal of Science & Technology 130 (2018)050-054 Developing Emission Factor Models for in-use Motorcycles Fueled by Gasoline, E5 and E10 Pham Huu Tuyen1*, Kazuhiro Yamamoto2, Preechar Karin3 1 Hanoi University of Science and Technology, No. 1, Dai Co Viet, Hai Ba Trung, Hanoi, Viet Nam 2 Nagoya University, Furo-cho, Chikusa-ku, Nagoya, Japan 3 King Mongkut's Institute of Technology Ladkrabang, Ladkrabang, Bangkok, Thailand Received: April 08, 2018; Accepted: November 26, 2018 Abstract Emissions from transportation sectors contain many toxic substances such as CO, HC, NOx, PM, etc. which cause environmental pollution and adverse effect on human health. In Vietnam, motorcycle is the most popular transportation means. However, motorcycles emit considerable amount of these pollutants. To estimate total emissions from motorcycles, it is necessary to determine the emission factors in certain working conditions. This paper develops the emission models of in-use motorcycles fueled by gasoline, E5 and E10 based on modal emission values which are collected from measurements on chassis dynamometer based on standard driving cycles. Keywords: emissions from motorcycles, total emissions, emission factor, in-use motorcycle 1. Introduction* categories and emission factors need to define for each vehicle category. The amount of pollutants can be calculated by using simple equation as below [1]: Motorcycle is one of the most popular transportation means in Vietnam as well as other Southeast Asian countries due to its low cost and flexibility. However, motorcycles emit substantial quantities of hydrocarbons (HCs), carbon monoxide (CO), nitrogen oxides (NOx) and small amount of particulate matter (PM). These pollutants have significant adverse health effects and deteriorate environmental quality. The contribution of motorcycle’s emissions to urban air pollution has become an increasingly common phenomenon, especially in big cities. In order to reduce emissions from transport .
