CFD Aided Development of a SI-DI Engine
CFD Aided Development of a SI-DI Engine — Gasoline Direct Injection (GDI) appears to be the most relevant way to improve fuel efficiency of SI engines. But today, GDI is essentially regarded as a suitable technology for relatively high displacement engines, and the literature shows that the R&D effort on GDI engines is generally made for bores larger than 80 mm. For small bore engines (bore bel...
متن کاملTurbulent Flame Velocity Model for SI Engine
A new model for turbulent flame velocity of premixed flame in spark ignition engine for Iso-octane air mixture has been developed and validated for a wide range of engine operating parameters. The model developed is a zero dimensional thermodynamic model. The effects of engine speed (600-1160 rpm), equivalence ratio (0.7-1.1), unburnt mixture temperature (532650 Rankine), compression ratio (5-8...
متن کاملINVESTIGATION OF FLAME STRUCTURE AND STABILITY FOR OXYGEN- ENHANCED COMBUSTION OF LOW CALORIFIC VALUE GASES By Mr. BISRAT YOSEPH (2011MEZ8167)
The gaseous by-product from natural or industrial processes which contain a small concentration of combustible gases is called a low-grade fuel or low calorific value gases (LCVG). Identifying the best strategy for efficient burning of such gases, where there is a bulk production, becomes inevitable to improve the efficiency of a system and reduction of pollutants emission. LCVGs have calorific...
متن کاملassessment of deep word knowledge in elementary and advanced iranian efl learners: a comparison of selective and productive wat tasks
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
Effect of Direct Injection Diesel Engine Convert to Sequential Injection CNG Engine in Intake Port Gas Flow Pressure Profile
The one dimension computational model of a sequential injection engine, which runs on compressed natural gas (CNG) with spark ignition, is developed for this study, to simulate the performance of gas flow pressure profile, under various speed conditions. The computational model is used to simulate and study of the steady state and transient processes of the intake manifold. The sequential injec...
