“…This is due to higher percentage increase in brake power with load as compared to increase in the fuel consumption. BSFC of bio-diesel blends are slightly higher for all experimental range of EGR compared to corresponding BSFC of diesel fuel [10,15]. This is presumably due to lower calorific value, higher boiling point and viscosity.…”

“…CO emissions are found to be lower for bio-diesel blends compared to diesel with and without EGR. CO levels increases as EGR rate increases for all three fuels [10,15,17,18]. The deficiency of oxygen with the increase in EGR % can be attributed to the rapid growth of CO.…”

“…This is due to the lower heating value of the bio-diesel blends. As EGR level increases NO emission decreases for all three fuels for all the operation range of engine brake power [10,15,17,18]. The reason for the greater reduction in NO with EGR is the reduction of combustion temperature as a result of the addition of exhaust gases to the intake air which increases the amount of combustion accompanying gases mainly CO2 which reduces the combustion temperature.…”

“…BTE is slightly increased with EGR at lower engine loads. This is presumably due to the re-burning of hydrocarbons that enter into the combustion chamber with the recirculated exhaust gas [10,15]. At higher engine loads, the BTE slightly decreased by EGR.…”

“…It can also be observed from other studies that reduced NOx emission can be achieved when CI engine run on fuel blends containing alcohol such as butanol (Lin et al, 2012;Rakopoulos et al, 2012). Other intervention to achieving NOx emissions reduction is Exhaust Gas Recirculation (EGR) as reported in the study by Venkateswarlu et al (2012).…”

Vegetable oils as fuel have received attention in recent years due to their advantages including renewable nature and domestically produced energy resources. Achieving reduced emission is important subject, as it enhances sustainability of biofuels. General factorial experimental design and analysis of variance (ANOVA) is used to analyze how NOx emission is influenced by alcohol content in vegetable oil-diesel fuel blends. Fuel samples 20% croton oil -80% diesel (20%CRO-80%D2), 15% croton oil -5% 1-butanol -80% diesel (15%CRO-5%BU-80%D2), and 10% croton oil -10% 1-butanol -80% diesel (10%CRO-10%BU-80%D2) were investigated. Four-cylinder compression-ignition (CI) engine was run at constant speed 3000 RPM, loaded at different loading conditions: low idle as 0 to 100% load condition. The specific fuel consumption and exhaust temperature of fuel blend containing butanol was measured. It was observed that nitrogen oxides (NOx) emission decreases as percentage of butanol alcohol content increases in fuel samples.

Exploration of sustainable fuels and their influence on reductions in diesel emissions are nowadays a challenge for the engine and fuel researchers. This study investigates the role of fuel-borne oxygen on engine performance and exhaust emissions with a special emphasis on diesel particulate and nitric oxide (NO) emissions. A number of oxygenated-blends were prepared with waste cooking biodiesel as a base oxygenated fuel. Triacetin, a derivative from transesterified biodiesel was chosen for its high oxygen content and superior fuel properties. The experimental campaign was conducted with a 6-cylinder, common rail turbocharged diesel engine equipped with highly precise instruments for nano and other size particles and other emissions. All experiments were performed in accordance with European Stationary Cycle (ESC 13-mode). A commercial diesel was chosen as a reference fuel with 0% oxygen and five other oxygenated blends having a range of 6.02-14.2% oxygen were prepared. The experimental results revealed that the oxygenated blends having higher a percentage of fuel-borne oxygen reduced particulate matter (PM), particle number (PN), unburned hydrocarbon (UBHC) and carbon monoxide (CO) emissions to a significantly low level with a slight penalty of NO emissions. The main target of this study was to effectively utilise triacetin as an additive for waste cooking biodiesel and suppress emissions without deteriorating engine performance. The key finding of this investigation is the significant reductions in both particle mass and number emissions simultaneously without worsening engine performance with triacetin-biodiesel blends. Reductions in both particle mass and number emissions with a cost-effective additive would be a new dimension for the fuel and engine researchers to effectively use triacetin as an emission suppressor in the future.
