Performance and emission tests of biodiesel fuels using a conventional diesel engine

The use of palm oil-based biodiesel fuel has been proposed as an alternative fuel for diesel engines in Malaysia. The main purpose of this study is to investigate the performance and exhaust emissions of several biodiesel blends of neutralized palm oil methyl ester (NPOME) in a small-unmodified dire...
