The cold start performance and ignition characteristics of coconut-oil methyl ester (CME) were investigated by using a diesel engine. Diesel fuel and CME were mixed and the blended ratio of CME was changed. The tests were conducted at full load and 3000 min -1 . Diesel engine could be run stably with any mixing ratio of CME, however the power was slightly reduced with increasing CME mixing ratio. In cold start condition, when the mixing ratio of CME increased, the combustion chamber wall
