“…Factorial is a good statistical technique for designing experiments, creating models, aiming effects of multiple variables, and finding optimum conditions for proposed responses. 41 In this study, a three-factor, three-level full factorial design as shown in Table 5 was utilized to design the experiments to be conducted. Injection timing, EGR and the alcohol type used in the blends were taken as factors that affect smoke and NOx emissions.…”

High carbon bio-alcohols have recently grabbed the attention of diesel engine researchers because of higher energy density, higher cetane number and better blend stability than their low carbon counterparts. This study utilizes three high carbon bio-alcohol/diesel blends prepared by mixing 40% by vol. of n -propanol, n -butanol and n -pentanol individually with fossil diesel in a DI diesel engine. Engine performance and emission characteristics were measured under high-load condition based on a 3 3 full-factorial experimental design matrix using exhaust gas recirculation (EGR) rate, injection-timing and alcohol type used in the blends as factors for controlling charge-dilution and combustion-phasing. A statistical investigation was then carried out to compare and analyze the effects of these factors on all measured responses like nitrogen oxides (NOx), smoke, hydrocarbons (HC), carbon monoxide (CO), brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC). Multiple regression models were developed for all responses using response surface methodology (RSM) and were found to be statistically significant at 99% confidence levels. Interactive effects between injection timing and EGR for all blends were compared and analyzed through response surface plots fitted using developed models with high R 2 values. Optimization was performed using desirability approach with an objective to minimize NOx, smoke and BSFC with maximum BTE. n-Propanol/diesel blend injected at 25° CA bTDC under 30% EGR with a desirability of 0.965 was predicted to be optimum for this engine. Similarly n-butanol/diesel and n-pentanol/diesel blends injected at 24°CA bTDC under 10% EGR were found to be optimum in their respective category. Confirmatory tests validated that the developed RSM models were adequate to describe the effects of injection timing and EGR on the engine characteristics as the predicted error is within 5%.

Transport of people and goods has always been associated with the generation of some pollution, whether atmospheric, sound or visual. Managing the urban environment presents a major challenge: preserving environmental resources and also ensuring decent living conditions for the current population and for future generations. In the era of motorized and carbonized transport, vehicles are the main source of emission of atmospheric pollutants, mainly in large urban centers and important precursors of ozone. An important advance in minimizing vehicle emissions was the introduction of cleaner and additive fuels into the Brazilian market. The aim of this study was to evaluate the influence of the use of 0.15% dienitro on S50 Diesel in engines with EGR (Exhaust Gas Recirculation) and S10 Diesel in engines with SCR (Selective Catalytic Reduction) and EGR system. The tests were performed with a gas analyzer directly on the exhaust of vehicles with engine speed of 1300 rpm. Results show CO emission reductions of 72.8, 37.9, 15.7% and NOx emission reductions of 48.0, 48.5 and 31.0%, respectively for the S50 EGR, S10 SCR and S10 EGR system. This additive has a slight increase of 1 or 1.5 points in cetane number, low vaporization enthalpy (energy to vaporize) and high combustion enthalpy, ie, Dienitro increased cetane number, faciliting the start of combustion and reducing CO. On the other hand, a fuel that releases less energy during combustion consequently produces lower temperatures within the combustion chamber, ie additives with lower combustion enthalpy have lower NOx emissions.

“…Kualitas bahan bakar yang kurang baik menjadi salah satu faktor penyebab ketidaksempurnaan atau efektivitas pembakaran. Berbagai penelitian telah dilakukan untuk meningkatkan efisiensi pembakaran, di antaranya pencampuran zat aditif pada bahan bakar yang mengakibatkan angka cetana naik serta proses pembakaran lebih baik dan daya mesin meningkat (Rahhal, Ghata and Hourieh, 2009;Fayyazbakhsh and Pirouzfar, 2015). Namun metode ini memiliki kekurangan yaitu hampir semua aditif kimia yang banyak beredar mengandung unsur logam yang membahayakan bagi kesehatan manusia.…”
