The Effects of Alternative Fuel Mixture of HDPE Plastic and Gasoline on Four-Stroke Engine Exhaust Gas Emissions

Alternative fuels, like a mix of pyrolyzed plastic waste and gasoline, have made us less dependent on nonrenewable petroleum. Since HDPE has a low density, it is perfect for producing more oil at temperatures as low as 400oCelsius. It has a density of around 0.94 g/cm3, whereas gasoline is between 0.60 g/cm3 and 0.78 g/cm3. This study compared a blend of C10 and C20 gasoline at engine speeds of 1500, 2000, and 2500 rpm to C0 gasoline. Results indicated that as speed increased, exhaust gas emissions such as HC and CO levels in pure gasoline (C0) dropped, whereas levels in the combination increased. This demonstrates that a mixture of gasoline and HDPE damages the environment.
