The advantages of biodiesel1. the benefits of using biodiesel environmentalThe use of biodiesel can reduce air pollution due to combustion of the engine complete. Department of the Navy "made trial of biodiesel pump with diesel engine. It was found that water used for biodiesel as fuel to reduce black smoke from more than 50 percent and reduce carbon gas (CO) is also common side 20 per cent reduction of 39 percent reduction in particulates has gas, sulfur dioxide was 99 per cent in addition to biodiesel substitutes diesel, it can reduce the life-cycle (life-cycle), carbon dioxide (CO2) gas has been 78 per cent as a result of global warming, reduce (U.S. Department of Energy, 2004).2. the benefits of using biodiesel engine performanceThe use of biodiesel in the engine to burn, because biodiesel is mixed with oxygen for about 10 per cent make the mixing between the air with oil is spread evenly and increases the volume of the air-fuel ratio as well as further (u.s. House of representatives energy, 2545 (2002)) It burns in the cylinder is completely. In addition, the increased torque value of about 7.5 per cent and 12 per cent increase in strength compared to diesel oil.Cons of biodiesel.Solid temperature is higher than diesel oil.Release the gas, nitrogen oxide is higher than diesel oil.Rubber parts deteriorate the quality of the oil pump is speed.Power, heat, about 10 percent less than diesel oil.To edit these cons may behave differently with mixed with diesel oil. For example, mixing diesel oil 80% to 20% ester Methyl salicylate
