“…On the basis of the results obtained, it can be seen that 100 % BD at 15 °C has a density of 0.8838 g/cm 3 . A slightly lower value of 0.882 g/cm 3 was reported by Baczewski and Szczawinski (2011) and 0.8823 g/cm 3 by Putrasari and Lim (2017a, 2017b, 2018. Chen et al (2017) reported a density value of 0.87 g/cm 3 for 100 % BD, which is also a little bit lower than our value.…”

“…Most of the researchers reported the biodiesel (BD)gasoline (G) blend impact on the gasoline compressed ignition (GCI) engine performance and emission (Putrasari and Lim, 2018;Putrasari and Lim, 2017a;Putrasari and Lim, 2017b;Adams et al, 2013) or the common rail diesel engine (Chen et al, 2017). These studies argue that BD -G blends have better low temperature fluidity and vaporization values then biodiesel itself.…”

The physical properties of any fuel are of significant importance to determining its suitability for a particular engine. The prediction of various properties of biodiesel or biodiesel blends with gasoline is vital to the design of different diesel engines. Therefore, the purpose of this paper is to examine the characterization of biodiesel density according to the standard testing methods employed in the present study. On the basis of the experimental material research in the field of biofuels, the effect of gasoline addition to biofuel on the biofuel properties was studied. The density of biofuel was found to decrease linearly with an increase in the blending ratio. Based on the data obtained, = 0.8838 g/cm 3 for 100 % biodiesel is not fully acceptable according to the referenced standards, and thus cannot be used in the United States without blending. However, this value is still within the acceptable range for use in the EU.

“…Furthermore, biodiesel has evidently decreasing engine exhaust pollutant [27,28], due to the high content of oxygen which important to minimize the soot development in combustion process [29]. The implementation of gasoline-biodiesel blends in GCI engine with single and double injection modes has been studied previously [30][31][32] The effect of biodiesel-gasoline blends on GCI combustion using 5% and 10% biodiesel was studied by Adams [30], which focused on reducing required intake temperature and utilization of split injection. To overcome the auto ignition difficulty of gasoline fuel without modification on intake temperature in GCI engine, the authors using a high compression ratio around 19.5 and various SOI of single injection mode in the previous study [31].…”

“…However, the combustion and emission characteristics of CI engines are also influenced by various other factors, such as fuel injection strategy, initial conditions and its combustion modes. Furthermore, based on previous study [30][31][32], the maintaining of high efficiency and emission reduction of GCI engine fueled with gasoline-biodiesel blends still challenging and need more to be optimized especially for its NOx and soot emissions. Since the auto-ignition sensitivity of gasoline fuel is influenced by several factors such as in-cylinder equivalence ratio, intake dilution, intake temperature and pressure, it is potentially to utilize EGR and boosting in GCI combustion.…”

A gasoline compression ignition (GCI) engine was proposed to be the next generation internal combustion engine for gasoline. The effect of exhaust gas recirculation (EGR) and intake boosting on combustion and emissions of GCI engine fueled with gasoline-biodiesel blends by partially premixed compression ignition (PPCI) combustions are investigated in this study. Tests were conducted on a single-cylinder direct-injection CI engine, with 5% by volume proportion of biodiesel in gasoline fuel blends. Engine control parameters (EGR rate, intake boosting rate, and various injection strategies) were adjusted to investigate their influences on combustion and emissions of this GCI engine. It is found that changes in EGR rate, intake boosting pressure and injection strategies affect on ignition delay, maximum pressure rise rate and thermal efficiency which is closely tied to HC, CO, NOx and smoke emissions, respectively.

“…[6][7][8] A small amount of biodiesel added into gasoline improves the auto-ignition of gasoline and reduces the intake temperature requirement while maintaining a high thermal efficiency and lower NO x and soot emissions. [7][8][9] In addition, biodiesel is a renewable fuel, so utilizing it to prepare this blend is a potential way to reduce emissions of greenhouse gases and other pollutants, as well as to address the shrinking reserves of fossil oil. [10][11][12][13] However, there are few studies concerning gasoline-biodiesel blended fuels, especially related to the ignition characteristics of the blend.…”

The purpose of this study is to demonstrate the effects of biodiesel fraction on auto-ignition for gasoline–biodiesel blended fuel, which combines two fuels with widely different auto-ignition characteristics. First, gasoline was blended with biodiesel at 5%, 10%, 15%, and 20% by volume, and then tested in a rapid compression expansion machine at a compression ratio of 11 and a temperature range of 720–850 K to observe the auto-ignition delay phenomenon under engine-like conditions. The experimental conditions are focused on improving the auto-ignition characteristic of gasoline direct-injection compression ignition combustion strategies under low load and cold start. The heat release rate of the blended fuels was calculated from the pressure trace and displacement history of the piston in order to identify first-stage ignition and second-stage (auto-ignition) ignition delay. Second, a gasoline–biodiesel reaction mechanism was developed to predict the chemical ignition delay of the blended fuels. The reaction mechanism with 4285 species and 15,246 reactions was validated and implemented using the CHEMKIN PRO software. Finally, the chemical ignition delay was predicted by the simulation which was further compared to the experimental measured results. These results revealed that a higher biodiesel fraction helps to obtain shorter ignition delay, which reduces the requirement of intake temperature. The blended fuel with 20% biodiesel showed the lowest ambient temperature at the injection timing requirement and was 80 K lower than gasoline. Each blended fuel exhibited two-stage ignitions in the measured temperature range. The combustion duration and pressure peak of every blended fuel were similar to each other after increasing the biodiesel fraction.
