The biodiesel fuel is a future fuel due to has oxygen in its chemical composition enhances thereby the chemical reaction process during combustion. The waste sunflower oil is selected for biodiesel preparation because it is commonly used as cooking oil. Furthermore, due to the climate circumstances of the Middle-east, very suitable for production the sunflower oil in a huge amount. This paper concern on studying the impact of using biodiesel prepared from waste sunflower oil and Iraqi conventional diesel on compression ignition engine performance and emissions. The samples of fuel were examined in a single cylinder, air cooled, naturally aspirated and four-stroke compression ignition engine. The biofuel is prepared by mixing the waste sunflower oil into a volumetric percentage of (5%,10%,15%,20%). The engine speed at which the engine performance and emissions measured are (1000,1300,1600,1900,2200,2500) rpm with different engine load. The practical results reveal that the CO, HC emissions are reduced up to (24.375%,35.71%) respectively, but the NOX and CO2 emission are increased by (22.62%,36.90%) respectively. The engine brake specific fuel consumption is increased by (12.11%).
