چکیده
این مقاله تاثیر ترکیب سوخت را بر موتور های GDI دارای سیستم توربوشارژر و کاربردهای آن را در ماشین های اسپرت است مشخصا تحقیقات بیشتری در زمینه ی تاثیر ات سوخت های یک ترکیبی به نسبت سوخت های ۷ ترکیبی (سوخت های سنتی) در مقالات موجود است. سوخت چند ترکیبی به "وسیله ی مدل مجزا سازی پیوسته" بررسی شده است و مشخصا به منظور بررسی تبخیر RON95 اروپا بررسی شده است. مقایسه ایی به منظور کالیبراسیون دقیق نسبت به داده های آزمایشگاهی موجود ، برای موتور در حالت بار کامل انجام شده است.
Abstract
The paper analyses the effects of fuel composition modelling in a turbocharged GDI engine for sport car applications.
Particularly, a traditional single-component gasoline-surrogate fuel is compared to a seven-component fuel model available in the
open literature. The multi-component fuel is represented using the Discrete-Continuous-Multi-Component modelling approach,
and it is specifically designed in order to match the volatility of an actual RON95 European gasoline. The comparison is carried
out following a detailed calibration with available experimental measurements for a full load maximum power engine speed
operation of the engine, and differences are analyzed and critically discussed for each of the spray evolution, mixture
stratification and combustion.
In the present paper (Part I), a RANS approach is used to preliminarily investigate the behaviour of the fuel model on the average
engine cycle. In the subsequent Part II of the same paper, the numerical framework is evo
