“…In this figure, it is observed that with the addition of ethanol to B5, there is a tendency of decreasing power as the ethanol content increases. According to RAHIMI et al (2009), using ED mixtures in a diesel cycle engine, a reduce performance, indicating that the addition of oxygenates in diesel oil reduces engine power. Other studies concluded that the lower stability, density, calorific value, and the higher water content of the mixture ED contribute to the reduction of engine power (TORRES-JIMENEZ et al, 2011;LAPUERTA et al, 2007).…”

“…The use of ethanol, besides reducing dependence on fossil fuel, would help to reduce emissions of greenhouse gases in the cycle diesel engine (RAHIMI, 2009 The addition of ethanol in diesel oil causes in the latter physical and chemical changes, noticeable reduction in cetane number, viscosity, and flash point (LI et al, 2005). These modifications change the characteristics of the fuel jet injected into the cylinder, the quality of combustion, and emissions of pollutants from the engine.…”

“…It can be seen that diesel fuel alone still producing the highest brake power compared to the E5 and E10 fuel. Diesel-ethanol blends reduces engine power output as the portion of oxygenated compounds (ethanol) in the blends increases [37]. This is due to the low cetane number and calorific value and higher ignition delay of the blends, compared to diesel fuel [38].…”

Abstract. This paper investigates the performance and emission characteristics of HCCI engines fueled with oxygenated fuels (ethanol blend). A modeling study was conducted to investigate the impact of ethanol addition on the performance, combustion and emission characteristics of a Homogeneous Charge Compression Ignition (HCCI) engine fueled by diesel. One dimensional simulation was conducted using the renowned commercial software for diesel and its blend fuels with 5% (E5) and 10% ethanol (E10) (in vol.) under full load condition at variable engine speed ranging from 1000 to 2750 rpm with 250 rpm increment. The model was then validated with other researcher's experimental result. Model consists of intake and exhaust systems, cylinder, head, valves and port geometries. Performance tests were conducted for volumetric efficiency, brake engine torque, brake power, brake mean effective pressure, brake specific fuel consumption, and brake thermal efficiency, while exhaust emissions were analyzed for carbon monoxide (CO) and unburned hydrocarbons (HC. The results showed that blending diesel with ethanol increases the volumetric efficiency, brake specific fuel consumption and brake thermal efficiency, while it decreases brake engine torque, brake power and brake mean effective pressure. In term of emission characteristics, the CO emissions concentrations in the engine exhaust decrease significantly with ethanol as additive. But for HC emission, its concentration increase when apply in high engine speed. In conclusion, using Ethanol as fuel additive blend with Diesel operating in HCCI shows a good result in term of performance and emission in low speed but not recommended to use in high speed engine. Ethanol-diesel blends need to researched more to make it commercially useable.

AbstractČUPERA, J., SEDLÁK, P., KARAFIÁT, P.: Diff erences in rheological profi le of regular diesel and bio-diesel fuel. Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 5, pp. 67-74 Biodiesel represents a promising alternative to regular fossil diesel. Fuel viscosity markedly infl uences injection, spraying and combustion, viscosity is thus critical factor to be evaluated and monitored. This work is focused on quantifying the diff erences in temperature dependent kinematic viscosity regular diesel fuel and B30 biodiesel fuel. The samples were assumed to be Newtonian fl uids. Vis cosi ty was measured on a digital rotary viscometer in a range of 0 to 80 °C. More signifi cant diff erence between minimum and maximum values was found in case of diesel fuel in comparison with biodiesel fuel. Temperature dependence of both fuels was modeled using several mathematical modelspolynomial, power and Gaussian equation. The Gaussian fi t off ers the best match between experimental and computed data. Description of viscosity behavior of fuels is critically important, e.g. when considering or calculating running effi ciency and performance of combustion engines. The models proposed in this work may be used as a tool for precise prediction of rheological behavior of dieseltype fuels. diesel fuel, biodiesel, kinematic viscosity, modeling Diesel fuel viscosity has a signifi cant impact on how well fuel (either regular or biodiesel) burns. As viscosity increases, fuel molecules cluster together. The molecules on the outside of the cluster mix well with oxygen during combustion and burn well. The molecules on the inside of the cluster do not mix as well and do not burn completely. Knowledge of fuel viscosity is important for several reasons, as it determines the temperature for handling, the size of the centrifuges and the temperature at which the fuel is injected into the engine. It is well known that as the temperature of the fuel is increased, the viscosity is reduced, but diff erences between individual blends or e.g. regular and biodiesel can be expected. Some fuel suppliers publish temperature/viscosity charts which are based on the average data of a large number of samples. However, estimations from the charts cannot be regarded as precise since the exact relationship depends on the source and composition of the fuel. The viscosity usually quoted is the kinematic viscosity expressed in centiStokes (cSt) at some reference temperature. Although ISO 8217 has a reference temperature of 100 °C, it is anticipated that this will be changed to 50 °C at the next revision. This is a value widely used throughout the industry. A few extra degrees of preheating can o en make a fuel suitable for injection equipment. Because of the viscosity/temperature relationship, a few degrees change could make a big diff erence to the injection viscosity. In practical terms, this means that if the actual fuel viscosity is greater than that ordered, it is likely that the fuel heater can accommodate this.Biodiesel refers to a vegetable o...
