Influence of intake air temperature on the performance of gasoline engines using a different type of fuel

The aim of the present study is to investigate effect Intake air temperature on performance gasoline engines. Various factors are taken that affect four-stroke Changes in intake have a significant impact petrol engine. Consequently, an increase or decrease global ambient will and quality engines particular. therefore, this investigation discover hot value temperatures effects engine performance.  This tested two Kurdistan-Iraq kinds at different (25Co, 35Co, 45Co, 50Co). Experiments utilized spark ignition _engine operated various rates speeds (1300, 1500, 1800, 2000, 2300 2500 revolutions per minute) under half load with 50% throttle opening. experimental outcomes were compared Ricardo Wave software simulations. Wave's theoretical good agreement experiment data it showed near 5% 10% variance between simulation practical data. Additionally, utilizing fuels having higher RON increases brake power owing gasoline's greater hydrogen content engine's high octane fuel requirement. Also, lower inlet would be denser (more oxygen) offer larger mass flow during each piston cycle. Hence, due those factors, was enhanced by reducing temp raising RON. Generally, results demonstrated number improved which demonstrates power, torque, efficiency bsfc gasoline.
