پاشش سوخت در موتورهای احتراق داخلی یکی از عوامل کلیدی در بهبود کارایی احتراق و کاهش آلاینده ها می باشد. عملکرد صحیح انژکتورهای سوخت نه تنها به نرخ پاشش بلکه به توزیع یکنواخت سوخت در فضای احتراق نیز کمک می کند. این عامل به شدت بر کارایی سوزاندن سوخت تأثیر می گذارد و می تواند به افزایش تولید توان و کاهش مصرف سوخت منجر شود. در این تحقیق به منظور تجزیه و تحلیل تجربی پارامترهای مؤثر بر نرخ و توزیع پاشش انژکتورها، مدل آزمایشگاهی از یک دستگاه تست انژکتور طراحی و ساخته شد. هدف از این مطالعه، درک بهتر روابط بین پارامترهای مؤثر و نحوه تأثیر آن ها بر عملکرد کلی سیستم های سوخت رسانی میباشد. این دستگاه قابلیت انجام تست های نشتی، بررسی شکل و مقدار پاشش انژکتورها را دارد. نتایج نشان داد افزایش زمان پاشش، افزایش فشار ریل سوخت و افزایش ولتاژ اعمال شده به انژکتورها باعث افزایش مقدار پاشش می شود و سرعت قطع و وصل برق انژکتورها و وجود یا عدم وجود فیلتر تأثیر چندانی بر میزان پاشش ندارد.
