چکیده

پارامترهایی که امروزه نقش مهمی در عملکرد موتور و بهبود احتراق دارد، فشار پاشش سوخت و زمان‌بندی پاشش می‌باشد. این مطالعه به بررسی عددی اثرات تغییرات فشار پاشش سوخت بر آلایندگی و عملکرد موتور دیزلی در قالب شبیه‌سازی عددی توسط نرم‌افزارAVL-FIRE می‌پردازد. در این تحقیق با ثابت نگه داشتن میزان مصرف سوخت و دور موتور مدت زمان پاشش اصلی از5 الی 12 درجه میل‌لنگ تغییر داده شد و به ازای این تغییرات، آلایندگی موتور مورد ارزیابی قرار گرفت. نتایج نشان داد که با کاهش مدت زمان پاشش سوخت، میزان آلاینده دی‌اکسید نیتروژن تا حدی افزایش و آلاینده دوده کاهش می‌یابد.
