چکیده
با توجه به استفاده بی‌رویه از منابع سوخت­های فسیلی در جهان، نیاز به منابع جدید تأمین انرژی در زمینه­های گوناگون از جمله کشاورزی دیده می­شود. استفاده از بیو­دیزل به‌عنوان سوختی غیر سمی، زیست دوست و تجزیه‌پذیر به‌عنوان راهکاری در این زمینه مطرح است؛ بنابراین، اهمیت بررسی شاخصه ­های عملکردی سوخت بیودیزل بر کسی پوشیده نیست. به­ همین منظور در این تحقیق بیودیزل در نسبت­های 0، 10، 20، 30 در­صد حجمی در یک مخزن فرعی مدرج با سوخت دیزل مخلوط گردید. آزمایش­ها در سه عمق 20، 25، 30 سانتی­متر و در سه سرعت 8/1، 6/3، 4/5 کیلومتر بر ساعت انجام شد. برای اندازه­ گیری نیروی کششی و سرعت واقعی از یک دینامومتر هشت‌وجهی کششی و یک رادار استفاده شد و با انجام آزمون فاکتوریل در قالب طرح بلوک کاملاً تصادفی، تأثیر فاکتور­های مستقل نوع سوخت، سرعت و عمق بر پارامتر­های اندازه­ گیری شده (سرعت واقعی، لغزش نیروی کششی، توان مالبندی) در یک سویل بین (انباره خاک) موردبررسی قرار گرفت. نتیجه تجزیه واریانس مربوط به­ داده­ های نوع سوخت، عمق کار، سرعت حرکت در مورد اثرهای اصلی و متقابل در سطوح احتمال 5 و1 درصد معنی ­دار شد. با توجه به ­نتایج تجزیه واریانس بین پارامترهای مستقل و وابسته اثر معنی­ دار به ­دست آمد. در هنگام استفاده از سوخت بیو­دیزل، نیروی کششی و توان کششی عملکرد بهتری داشت.

Abstract
By depletion of fossil fuel resources in the world, the need for the new resources in the various field and among them in agriculture has raised. The use of biodiesel as a renewable, non-poison and eco-friendly fuel is a significant solution in this area. In this relation, evaluating the performance characteristics of biodiesel has vital importance. In this research, the experiments were performed using 0, 10, 20 and 30% biodiesel mixed with diesel in a sub-scale tank for evaluating the mixture performance in tractor traction. Diesel fuel was used as the basis for comparisons. The experiments were performance in three tillage depths of 20, 25 and 30 cm, and in three forward speeds of 1.8, 3.6 and 5.4 km/h. For drawbar force measurement an octagonal ring drawbar dynamometer and for real speed a radar were used. The tests were performed in the factorial completely randomized design. The different fuel factors effect were measured on tractor performance parameters (real speed, drawbar force, slip, traction power) in a soilbin. Analyses of variances for the experiments showed that the real speed, slip, drawbar power, traction force and their interaction effects were significant at 5% and 1% of probability level. Adding biodiesel for tractor fuel increased the values for drawbar force and drawbar power.
