In this study, ethanol and diisopropyl ether were combined with base gasoline in three different volume ratios. The XU7JP/L3 engine was selected to test the effect of fuel additives on engine performance and emission parameters. Engine performance parameters were recorded simultaneously by a computer device at the time of the test, and engine output pollutants were manually recorded by a pollutant meter. The results showed that with the addition of oxygenated additives to gasoline, the oxygen in the fuel-air mixture was increased, the fuel was closer to the stoichiometric conditions and the combustion was more complete. As a result, the engine's torque and brake power increased and its brake-specific fuel consumption decreased. Oxygenated additives also reduced carbon monoxide and unburned hydrocarbons and increased carbon dioxide and nitrogen oxides. The results of increasing diisopropyl ether additive compared to ethanol additive in combination with base gasoline also showed that the amount of carbon monoxide, unburned hydrocarbon, and nitrogen oxide pollutants is higher and the amount of carbon dioxide production is lower.
