This work analyzes the use of alternative sources of energy to reduce the consumption of diesel oil in the diesel power plants of the isolated system. Blends of palm oil with diesel and hydrogen gas produced by electrolysis of water were used. The blends used as fuel were composed of 20% palm oil and 80% diesel oil. The HHO gas produced by an electrolytic cell was injected into the engine intake air. The experimental results show that the electric current directly influences the production of HHO gas, allowing the control of the amount of gas to be made by the adjustment of the electric current. Using the diesel / vegetable oil mixture with the HHO gas injection in the intake air, we identified reduction in specific fuel consumption, reductions in CO, HC and CO2 emissions as the amount of HHO gas injected increased. These results will lead to significant reductions in diesel oil consumption and exhaust gas emissions from the generator sets of thermoelectric power plants in the isolated system.
