چکیده

کمبود سوخت‌های فسیلی، افزایش بهای انرژی و ملاحظات زیست محیط سبب شده تا بسیاری از کشورها به سوخت‌های زیستی و تجدیدپذیر روی بیاورند. در موتورهای احتراق داخلی استفاده از سوخت‌های فسیلی بسیار رایج است که مصرف بسیار زیادی نیز دارند. یکی از روش‌های کاهش مصرف سوخت‌های فسیلی استفاده از سوخت‌های زیستی نظیر الکل‌ها در موتورهای احتراق داخلی هست. مطالعه حاضر با هدف ارزیابی تراز انرژی یک موتور بنزینی چهار سیلندر آب خنک با استفاده از ترکیبات سوخت بنزین و الکل‌های اتانول، بوتانول، پروپانول و پنتانول در درصدهای حجمی مختلف در سه دور مختلف rpm 1000، 1500 و 2000 انجام شد. نتایج نشان داد توان ترمزی موتور آزمایشی ترکیبات سوخت در درصدهای حجمی مختلف رفتار متفاوتی از خود نشان می‌داد و با توجه به میزان پروپانول و بوتانول میزان توان ترمزی متفاوت است. بیشترین توان ترمزی مربوط به سوخت شماره 6 در سرعت rpm2000 به میزان kw47/11 و کمترین مقدار مربوط به سوخت شماره 1 به میزان kw 21/81 در سرعت rpm1000 بود. بیشترین مقدار تلفات حرارتی سیستم خنک کننده مربوط به سوخت شماره 6 به میزان kw10/84 در سرعت rpm1000 و کمترین مقدار مربوط سوخت شماره 1 به میزان kw 77/7 در سرعت rpm1000 بود. بیشترین تلفات حرارتی اگزوز مربوط به سوخت شماره 6 به میزان kw 17/07 در سرعت rpm2000 و کمترین مقدار مربوط به سوخت شماره 2 به میزان 14/54 در سرعت rpm1000 بود. بیشترین تلفات حرارتی محاسبه نشده مربوط به سوخت شماره 2 به میزان kw18/57 در سرعت rpm2000 و کمترین مقدار مربوط به سوخت شماره 5 به میزان kw11/47 در سرعت rpm1000 بود.

چکیده [English]

The lack of fossil fuels, the increase in energy prices and environmental problems have caused many countries to switch to biofuels and renewables. The lack of fossil fuels, the increase in energy prices and environmental problems have caused many countries to switch to biofuels and renewables. with the aim of evaluating the energy balance of a four-cylinder water-cooled gasoline engine using gasoline fuel compounds and ethanol, butanol, propanol, and pentanol alcohols in different volume percentages at three different speeds of 1000, 1500, and 2000 rpm. The results showed that the braking power of the experimental engine showed different behavior in different volume percentages of the fuel compounds, and according to the amount of propanol, butanol and pentanol, the amount of braking power is different. The highest braking power related to fuel number 6 at the speed of 2000 rpm was 47.11 kW and the lowest value related to fuel number 1 was 21.81 kW at the speed of 1000 rpm. The highest amount of heat loss of the cooling system related to fuel number 6 was 10.84 kW at a speed of 1000 rpm and the lowest value related to fuel number 1 was 17.07 kW at a speed of 1000 rpm. The highest exhaust heat loss related to fuel number 6 was 17.07 kW at the speed of 2000 rpm and the lowest value related to fuel number 2 was 14.54 at the speed of 1000 rpm. The highest uncalculated heat loss related to fuel number 6 was 18.57 kW at 2000 rpm speed and the lowest value was related to fuel number 5 at 11.47 kW at 1000 rpm speed.
