Research of Effect on Gasoline-2-Propanol Blends on Exhaust Emission of Gasoline Engine with Direct Injection Using Taguchi Approach

Research of Effect on Gasoline-2-Propanol Blends on Exhaust Emission of Gasoline Engine with Direct Injection Using Taguchi Approach

One of the most important causes of global warming is the greenhouse gas effect caused by the increased $CO_2$ emission due to the use of petroleum-based fuels in internal combustion engines. $O_2$ , $H_2O$, $NO_X$ emissions released as a result of the combustion reaction and released into the atmosphere from the exhaust turn into nitric acid ($HNO_2$) as a result of some reactions taking place in nature. In addition, the OH radicals released as a result of these reactions that can not turn into nitric acid react with the ozone layer ($O_3$) and support the formation of hydroperoxyl ($HO_2$), which causes a harmful emission cycle. CO emissions, on the other hand, react with $O_2$and $NO_X$ and pollute the water vapor in the air, causing the $O_2$level to drop. Despite quite a lot of work done to date, it is known that due to the increase in the number of gasoline engines, their environmental damage is excessive. In this study, the effect of 2-Propanol / Gasoline fuel mixtures on exhaust emission values has been experimentally investigated using Taguchi Approach. The input factors for Taguchi Approach are 2-Propanol ratio and Engine speed and output values are determined as carbon monoxide (CO), carbon dioxide ($CO_2$), hydrocarbon (HC), Nitrogen Oxide ($NO_X$), and Oxygen ($O_2$) emissions. In the created Taguchi design, experiments were planned by using an L9 orthogonal array. The engine speed was determined as 1500, 2500, and 3500 (rpm), and 2-propanol ratio was determined as 5%, 10%, and 15% (% by volume). Tests were conducted under partial load conditions. In tests conducted at 1500 rpm, CO emissions decreased by 41.99% compared to gasoline, while $CO_2$, HC, $NO_X$ and $O_2$emissions decreased by 7,09%, 20,91%, 8.64%, and 20.34%, respectively. 2500 rpm test, CO, $CO_2$, HC, $O_2$, and $NO_X$reductions in emissions, respectively 16.60%, 2.09%, 17.39%, 10.64%, and 27.14% 3500 rpm, while the rate of decrease of the emission test values, respectively 25.30%, 4.88%, 29.09%, 9.72%, and 37.09% has been found in
