چکیده

در این تحقیق، با هدف بهبود متغیرهای سیستم سوخت‌رسانی و جرقه‌زنی، تأثیر میزان کارکرد فیلتر سوخت بر میزان دمای بنزین خروجی از پمپ سوخت، پیش‌رسی جرقه، فشار پاشش انژکتورها و میزان جریان الکتریکی پمپ سوخت یک موتور بنزینی، به‌صورت تجربی بررسی شد. نتایج این تحقیق نشان داد که کمترین دمای بنزین خروجی از پمپ سوخت و میزان جریان الکتریکی آن با استفاده از فیلتر نو (صفر کیلومتر) به‌ترتیب برابر  A88/2 و ˚C 5/37 و بیشترین دمای بنزین خروجی از پمپ سوخت و میزان جریان الکتریکی آن با استفاده از فیلتر با کارکرد 60000 کیلومتر به‌ترتیب برابر  A12/4 و ˚C 5/40 خواهد بود. همچنین بیشترین میزان فشار پاشش انژکتورها و کمترین مقدار پیش‌رسی جرقه در دور موتور rpm  1000 با استفاده از فیلتر نو (صفر کیلومتر) به‌ترتیب برابر bar 5/3  و 7 درجه و کمترین میزان فشار پاشش انژکتورها و بیشترین مقدار پیش‌رسی جرقه در دور موتور rpm  5000 با استفاده از فیلتر با کارکرد 50000 کیلومتر به‌ترتیب برابر bar 5/2 و 37 درجه مشاهده شد. نتایج این تحقیق نشان داد که فیلترهایی با کارکرد بیش از 15000 کیلومتر موجب کاهش کیفیت احتراق و راندمان موتور می‌شوند.

چکیده [English]

In this study, the effect of fuel filter lifetime on the temperature of gasoline output from the fuel pump, ignition advance, injector injection pressure and electric current of the fuel pump of a gasoline engine was examined experimentally with the aim of improving the variables of fuel and ignition systems. The results of this study showed that the lowest temperature of gasoline output from the fuel pump and the amount of electric current of the pump using a new filter were 37.5 ˚C and 2.88 A, respectively. The highest temperature of gasoline output from the fuel pump and the amount of electric current of the pump, measured using a filter with a range of 60,000 km, were 40.5 ˚C and 4.12 A, respectively. The highest injection pressure of the injectors and the lowest amount of ignition advance at 1000 rpm engine speed and using the new filter were 3.5 bars and 7 degrees, respectively. The lowest injection pressure of the injectors and the highest amount of ignition advance at 5000 rpm engine speed by using a 50,000 km filter lifetime were reported as 2.5 bars and 37 degrees, respectively. It is lucid that filters with a lifespan of more than 15,000 km reduce the combustion quality and efficiency of the engine.
