Reduction of Emission in a Dual Fuel C.I. Engine Using Biodiesel Mixed with DMC Additive

Abstract

People are experiencing price rises, economic instability, and suffering as a result of rising fuel prices and oil imports. In a "green" movement, alternative fuels are being embraced as a better energy source, primarily in the transportation industry. Alternative fuel vehicles produce fewer emissions, which is good because emissions cause smog, air pollution, and global warming. This is why the movement is becoming more and more popular. Because of its shortcomings, neat biodiesel is not suitable for use in engines. A detailed investigation reveals that poor quality biodiesel fuel is the cause of most of problems. Some of the problems especially, cold weather are not attributable to poor fuel quality, but rather to the intrinsic characteristics of biodiesel fuel. Different kinds of additives are mixed into the fuel to solve these issues and enable the engine to function more efficiently. In comparison to diesel and biodiesel, very little is used in the way of additives. Additives are used to modify the qualities of biodiesel as much as feasible. This work deals with the engine emissions of a dual fuel compression ignition engine using Argemone Mexicana bio-diesel blended with Dimethyl Carbonate (DMC) as an additive. Argemone Mexicana biodiesel was prepared by trans-esterification process followed by esterification. Initially experiments were conducted taking diesel, B25 (25% biodiesel), B45 (45% biodiesel) and B65 (65% biodiesel at various engine loads. After that 5ml DMC was added in 1liter B25, B45 and B65 fuel sample for the experiment purpose. An exhaust gas analyzer was used to measure the emissions of engine. During experiments an exhaust gas analyzer was connected to measure CO, HC and NO_x emissions.
