چکیده

در این تحقیق ارتعاشات حاصل از مصرف ترکیبات مختلف سوخت های بیودیزل، بیواتانول و دیزل در موتور تراکتور MF285 بررسی گردید . شتاب RMS ارتعاشات موتور در سه جهت و سه دور موتور 1000، 1600و rpm 2000 و ده ترکیب مختلف سوخت اندازه گیری شد. برای بررسی ارتعاش موتور تحت تأثیر پارامترهای اندازه گیری شده از طرح آماری فاکتوریل در قالب بلوک کامل تصادفی و روش سطح پاسخ استفاده شد. نتایج نشان داد که ارتعاش حاصل از مصرف ترکیبات مختلف سوختی کمتر از ارتعاش در اثر مصرف سوخت دیزل خالص می باشد. همچنین نتایج نشان داد که با افزایش بیودیزل در ترکیب سوخت ها میزان ارتعاش به طور معنی داری کاهش و با افزایش دور موتور میزان ارتعاش افزایش یافت. همچنین با افزایش بیواتانول تا 4 درصد مقدار ارتعاش کمی افزایش و سپس اندکی کاهش یافت. پس از بهینه سازی، بهترین سوخت از لحاظ داشتن کمترین ارتعاش موتور به روش سطح پاسخ سوخت B25E6D69  بدست آمد. در صورتی که تجزیه و تحلیل آماری سوخت B25E4D71   را بهترین سوخت معرفی نمود. در هر حال استفاده از بیودیزل با درصد حجمی 25 درصد سبب کاهش ارتعاشات موتور گشت.

چکیده [English]

In this study, the MF285 tractor engine vibrations resulting from the use of different combinations of biodiesel, bioethanol and diesel as fuel were studied. Engine vibrations in three directions and three engine speeds: 1000, 1600 rpm 2000 and ten fuel level was measured. To investigate the influence of measured parameters on engine vibration of factorial design in a randomized complete block design and response surface methodology were used. The results showed that vibration caused by the use of different combinations was less than of vibration caused by consumption of diesel fuel. The results showed that with increasing biodiesel fuel blends significantly reduce the vibration and the vibration increases with increasing engine speed. The vibration increased by increasing the bioethanol until 4% but then decreased. After optimization, the best fuel in terms of having the lowest vibration motor was B25E6D69.
