In the case of vegetable oil used as a fuel, the CO_2 emission decreases because of its lowest WTW (well to wheel) among thevarious fuels. Among a lot of various vegetable oil, Palm oil is most cheapest, and the another fuel named a Dimethyl Ether (DME) is produced from biomass, because DME is synthesized from CO and H_2. The kinematic viscosity of Palm oil is very high such as 59.1cSt, and that of DME is very low such as 0.16 cSt at romm condition. Therefore, the blend of two fuel make a good fuel for diesel engines such as a kinematic viscosity from 2 to 4 cSt.The blend ratio of 20% to 40% of DME into the palm oil is used as a fuel for diesel engine, as a result, the engine performance is comparable to that of neat diesel oil operation, and the soot emission of blended fuel operation is 10% of that of diesel oil operation at high load.
