O-05 Evaluation of Exhaust Emission Performance When Using Biodiesel and Understanding of Actual Status of Biodiesel Utilization by Questionnaire Investigation

Abstract

Ethaust emission performance when using biodiesel was evaluated by the application of a number of biodiesels to diesel vehicle complying with new long-term regulation. All emissions were not varied between all biodiesels, although all biodiesels increased NOx emission, compared with conventional diesel fuel. In addition, the questionnaire investigation to biodiesel users was conducted for understanding of the actual status of biodiesel utilization in Japan. This result showed that more than half of biodiesel users experienced vehicle troubles associated primarily with fuel injection system.
