The present work investigated the laminar flame speed measurement of kerosene-relevant fuel, including Jet A-1 commercial kerosene, and surrogate kerosene fuel and its pure components (n-decane, n-propyl benzene, and propyl cyclohexane) using a high-pressure Bunsen flame burner. The OH* chemiluminescence technique and the kerosene-PLIF technique were used for flame contours detection in order to calculate the laminar flame speed. The experiments were first conducted for n-decane/air flame at T = 400 K, φ = 0.6−1.3, and atmospheric pressure conditions in order to validate the whole experimental system and measurement methodology. The laminar flame speed of Jet A-1/air, surrogate/air, and pure kerosene component (n-decane, n-propyl benzene, and propyl cyclohexane) was then measured under large operating conditions, including temperature T = 400−473 K, pressure P = 0.1−1.0 MPa, and equivalence ratio φ = 0.7−1.3. It was found that these three pure components of kerosene have very similar laminar flame speed. By comparing the experimental results of surrogate kerosene and Jet A-1 commercial kerosene, it was observed that the proposed surrogate kerosene, i.e., mixtures of 76.7 wt % ndecane, 13.2 wt % n-propyl benzene, and 10.1 wt % propyl cyclohexane, can appropriately reproduce the flame speed property of Jet A-1 commercial kerosene fuel. The experimental results were further compared with simulation results using a skeletal kerosene mechanism.

“…McCormick et al [18] mentioned the positive effect of anisole blending on research octane number (RON) but also reported a negative effect on the distillation curve, especially the 50% evaporation temperature (T50), for blends with gasoline. Anisole is seen as a promising SI fuel component primarily due to its high RON [38] and octane sensitivity [39], low reactivity [40], and high laminar flame speed [41]. Despite this, few engine tests with anisole blends have been reported in the literature so far.…”

Several countries have set ambitious targets for the transport sector that mandate a gradual increase in advanced biofuel content in the coming years. The current work addresses this transition and indicates two promising gasoline bio-blendstocks: Anisole and isobutanol. The whole value chains of these bio-components were considered, focusing on end-use performance, but also analyzing feedstock and its conversion, well-to wheel (WTW) greenhouse gas (GHG) emissions and costs. Three alternative fuels, namely a ternary blend (15% anisole, 15% isobutanol, 70% fossil gasoline on an energy basis) and two binary blends (15% anisole with fossil gasoline and 30% isobutanol with fossil gasoline), were tested, focusing on their drop-in applicability in spark ignition (SI) engines. The formulated liquid fuels performed well and showed the potential to increase brake thermal efficiency (BTE) by 1.4% on average. Measured unburned hydrocarbons (HC) and carbon monoxide (CO) emissions were increased on average by 12–29% and 17–51%, respectively. However, HC and CO concentrations and exhaust temperatures were at acceptable levels for proper catalyst operation. The studied blends were estimated to bring 11–22% of WTW GHG emission reductions compared to base gasoline. Additionally, the fleet performance and benefits of flexi-fuel vehicles (FFV) were modeled for ternary blends.

The blends of fuel to base liquid fuels for the enhancement of combustion properties has long generated interest since it is linked to improvement in combustion properties in biodiesel fuels. This work investigates the effect of bentonite nanoparticles on the combustion characteristics of palm oil biodiesel. These nanoparticles are added in various compositions on biodiesel which are 0% (B0), 10% (B10), 20% (B20) and 30% (B30). The insulin pen was used to make Sub-millimeter-sized spherical droplets, and the combustion process of droplets was recorded using a camera in atmosphere condition. The fuel was dripped on the tip of the thermocouple junction and ignited using a torch of the butane-air mixture on a cylindrical burner. Properties such as ignition delay, burning rate, and flame temperature of droplets were measured with post-processing of the resulting images. The results showed a decrease in ignition delay and an increase of flame temperature with the increase of bentonite percentage due to bentonite acts as a catalyst capable of accelerating the reaction rate. However, the burning rate decrease with the increasing of bentonite percentage due to the oxygen content of the mixture is getting lower.
