Investigation of the use acetone as an additive in diesel engines

Abstract

In this study, the use of acetone as an oxygenated liquid fuel additive in diesel engines was investigated. Before the tests, a mixture fuel was created by adding 3% acetone by volume to the diesel oil. Combustion and emission characteristics were investigated by using a diesel engine at 1500 constant engine speed and different average effective pressures (BMEP). Results; With the addition of 3% acetone to diesel fuel, increases were observed in all combustion parameters (in-cylinder pressure, pressure increase rate, average gas temperature, heat release rate). While reductions in carbon monoxide emissions were observed, increases in azocoxides were observed.
