Abstract : Opposed piston engines are a revolutionary approach in order to increase efficiency and to reduce pollution. Unlike the conventional 4-stroke engines opposed piston engines are smaller in size. The operation is completed within two strokes yet with the same effect. The opposed piston cylinder engines consists of two opposing pistons reciprocating within a single cylinder . The number of moving parts are extremely less causing a drastic reduction in the production of heat , thereby reducing emissions and also increasing efficiency. They have higher expansion ratios and proven longevity. Super charging is easily achieved. Since they have half the number of cylinders there is a 32% reduction in weight. This paper discusses the general working of an OPE along with the methods by which opposed piston engines along with their present merits can be used to reduce pollutant emission. Emulsified fuel in which diesel and fuel is mixed together can be used to drastically reduce NOx emission because the water decreases the peak temperature of combustion . The use of emulsified fuel also decreases particulate emission, but the overall effect on the power development is less . Opposed piston engines can also be powered by a mixture of diesel, biodiesel and nanoparticle additives like cerium oxide. The flash point and fire point is improved by the additive . The additive reduces the specific fuel consumption and also NOx emission is reduced by the improved atomisation caused by the additive . Index Terms— Opposed Piston Engines , Bio Diesel , Emulsified Fuel, Nano Particle Additives.
