Excellent potential exists for Brazilian agriculture to develoop a vegetable oil program as a substitute for diesel oil. Vegetable oils have surprisingly good fuel properties for application in compression ignition engines. One of the major limitations is the higher viscosity of vegetable oils which can be significantly improved by transesterification. Successful engine tests have been completed with both indirect-injected (IDI) engines and direct-injected (DI) engines in Brazil. Results are more encouraging for IDI than those for DI engines. With the current international oil prices the use of vegetable oils as a substitute for diesel oil is not feasible. However, research programs should be continued in Brazil since the petroleum price may increase in the future.
