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

Abstract

Internal combustion engines are quite widely used today. Much work is being done to reduce the environmental damage of internal combustion engines, reduce fuel consumption and improve engine performance values. 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 use on emission characteristics was investigated. 2-Propanol (%5, %10, and %15 by volume) mixed with gasoline fuel, tests were conducted with a direct injection engine. Tests were conducted under full load conditions. Compared to the gasoline reference fuel and the blended fuels prepared with different percentages, it was observed that the CO and HC emission values decreased, and the CO2, O2, and NO emission values increased as a result of the use of 2-Propanol.
