This paper presented experimental results of an investigation on a compression ignition engine fueled with ultra low sulfur diesel fuel (ULSD) and palm methyl ester (PME) with naturally aspirated hydrogen at various engine loads. CO was observed to reduce almost proportional to the quantity of hydrogen added while HC increased at lower load, but decreased at medium-to-high loads. NOx emission reduced for ULSD and increased for PME when hydrogen was added. Hydrogen could reduce particulate mass concentration at medium-to-high loads. The geometry mean diameter (GMD) of the particles decreased with the increase of hydrogen added at low and medium loads but increased at high load. The particle total number concentration (TNC) reduction with hydrogen was more effective for PME than ULSD.
