TI  - Investigation of the Effects of Gasoline-Bioethanol Blends on Engine Performance and Exhaust Emissions in a Spark Ignition Engine
AB  - In this study; 95 octane unleaded gasoline and bioethanol were tested as fuel in a spark-ignition engine byblending bioethanol with gasoline in certain proportions (2%, 4%, 6%, 8%, 10%). Tests were carried out at fivedifferent engine loads for a constant engine speed of 2500 rpm. The variations in engine performance parameters(engine torque, engine power, brake thermal efficiency, brake specific fuel consumption, brake specific energyconsumption) and exhaust emissions (exhaust gas temperature, HC, CO, CO2 and O2) were investigated on thebasis of test fuel and engine load. According to the test results, with the increase of bioethanol ratio in the blend,brake specific fuel consumption values increased by 9.71% and brake thermal efficiency values decreased byapproximately 4.97% compared to gasoline. There was decrease up to 35.56% and up to 23.77% in HC and COemissions respectively, and an increase by 6.01% in CO2 emissions with bioethanol addition.
