This experimental work evaluates the effects of Green Algae Methyl Ester (GAME) biodiesel blends on diesel engine performance and emissions under different injection timings and EGR conditions. The highest Brake Thermal Efficiency of 31.15% was obtained at 27° bTDC for GAME20, which is moderate lower than diesel 31.7%. The minimum BSFC was 0.26 kg/kWh at 23° bTDC, which is compared to 0.24 kg/kWh for diesel. The investigation of GAME20 exhibited reduced NOx emissions is achieved 720 ppm with 30% EGR compare to 972 ppm for diesel and reasonable CO emissions which is compare to 0.165% and Diesel 0.132%. Smoke opacity for GAME20 was recorded at 67.5%, so, it is lower than diesel 69%. The investigation of GAME biodiesel with EGR focusing the NOx emission reduction to suggestions a cleaner and sustainable alternative to diesel with minimal changes.
