چکیده
در کار پژوهشی حاضر یک موتور پژوهشی دارای سیستم اندازه‌گیری مورد نیاز همراه با تجهیزات آزمایشگاهی، دست‌آوردهای تجربی احتراق نرمال (بدون کوبش) در نسبت تراکم 11، در دو سرعت موتور متفاوت و نسبت هم ارزی استوکیومتری در آوانس‌های متفاوت (انتخاب آوانس بهینه از حداقل 6 آوانس) برای حالت‌های G100 (صددرصد بنزین)، G87.5 (87/5 درصد بنزین مابقی گاز طبیعی)، G75 (75 درصد ینزین مابقی گاز طبیعی) و G62.5 (62/5 درصد بنزین مابقی گاز طبیعی) مستخرج گردید. برای اطمینان از داده‌های تجربی از 350 چرخه متوالی اطلاعات اخذ و ذخیره شده است و پس از تحلیل اطلاعات توسط یک کد کامپیوتری نتایج خام به نتایج مورد استفاده تبدیل گردید. از نتایج تجربی به دست آمده برای تجزیه و تحلیل احتراق، آلایندگی و عملکرد ترکیب بنزین و گاز طبیعی استفاده شد. در جمع‌بندی این نتایج، فشار اندیکه داخل موتور و گشتاور خروجی ترکیب سوخت‌های گازدار قابل مقایسه با حالت بنزین‌سوز بود. نتایج نشان می دهند که با افزایش گاز طبیعی و سرعت موتور میزان آلاینده های CO، HC و NO به شدت کاهش می‌یابند.

چکیده English

In the present research work, a research engine with the required measurement system along with laboratory equipment, experimental results of normal combustion (without knocking) at a compression ratio of 11, at two different engine speeds and stoichiometric equivalence ratio at different advances (selection of the optimal advance from at least 6 advances) were extracted for the conditions of G100 (100% gasoline) , G87.5 (87.5% gasoline remaining natural gas) , G75 (75% gasoline remaining natural gas) and G62.5 (62.5% gasoline remaining natural gas). To ensure the experimental data, information was obtained and stored from 350 consecutive cycles. After analyzing, the information was converted from raw results to usable results by a computer code. The experimental results were used to analyze the combustion, emissions, and performance of the gasoline and natural gas blend. In summary, the IMEPAV (average indicated mean effective pressure) and torque output of the gaseous fuel blend were comparable to the gasoline-burning state, while the levels of CO, HC, and NO pollutants were greatly reduced with increasing natural gas and engine speed.
