“…Octane number butanol yang tinggi menjadi faktor dominan mesin menghasilkan torsi dan daya optimal. Hal ini karena langkah kompresi menjadi lebih panjang sehingga tekanan dan temperatur dalam silinder meningkat dan gaya dorong piston saat langkah usaha lebih besar akibat hasil ledakan tersebut [11]. Yuanxu li dkk., [12] juga meneliti efek butanol pada mesin bensin terhadap konsumsi bahan bakar.…”

The increase in the volume of vehicles resulted in a crisis of fossil fuels so there is a need for alternative fuels to replace gasoline. Butanol and Diethyl Ether (DEE) are alternative fuels that can be added to gasoline. This is because the Octane Number and high O2 levels optimize combustion in the cylinder and increase torque and power and save fuel. This study compares the addition of butanol and DEE to gasoline on torque, power, and Brake Specific Fuel Consumption (BSFC). The study used a 160cc gasoline engine with a carburetor with engine speeds of 1000, 2000, and 3000 rpm. Variation of fuel mixture 5%, 10%, and 15% on gasoline. The results showed that the DEE15 mixture increased the highest torque by 28% at 3000 rpm compared to other fuel mixtures. Engine power also increases the highest by 28% when using a mixture of DEE15 compared to other fuels. Meanwhile, BSFC experienced the highest decrease of 19% when using the DEE15 mixture compared to other mixtures.

“…CO emission also increases (0.38 to 0.53 (% vol)) as a consequence of poor combustion efficiency and reduced cylinder temperature. Higher compression pressure and temperature as the SOI2 delays, lead to the smaller droplet size of injected fuel as well as lesser wall impingement since the cylinder pressure is higher, this results in a drop in HC emission from 280 to 205 ppm (Qian et al, 2019).…”

“…However, the low cetane number (CN), high latent heat of evaporation, poor miscibility, and poor lubricating properties result in many drawbacks when using them in compression ignition (CI) engines. Pentanol being longer-chain alcohol, which exhibits higher energy density, higher CN, better solubility, and less hygroscopic compared to lower alcohols like ethanol, methanol, and even butanol, has been confirmed to have better performance for application in CI engines and was treated as the most promising diesel alternative . Furthermore, pentanol can be also produced from biological pathways like biosynthesis from glucose using Escherichia coli and natural microbial fermentation using engineered microorganisms .…”

3-Pentanol is a potential alternative fuel or a green fuel additive for modern engines. The H-abstraction reactions from 3-pentanol by H, CH 3 , HO 2 , and OH radicals are significant in the 3-pentanol oxidation process. However, corresponding rate constants are forced to rely on either analogy from sec-butanol or estimation from alkanes due to a lack of direct experimental and theoretical study. In this work, stationary points on the potential energy surfaces (PESs) were calculated with the high-level DLPNO-CCSD(T)/CBS(T-Q)// M06-2X/cc-pVTZ method, which is further used to benchmark against the CBS-QB3 method. Then, the high-pressure limit rate constants for target reactions, over a broad range of temperature (400−2000 K), were calculated with the phase-space theory and conventional transition state theory. A comparison was made between the calculated rate constants and the values available in Carbonnier et al. [Proc. Combust. Inst. 2019, 37(1), 477−484]. The rate constants for the above H-abstraction reactions in the Carbonnier model were updated with the calculated results, followed by a modification based on the computed results of 3-pentanol + HO 2 to obtain the revised model. Validation against the shock tube (ST) and the jet-stirred reactor (JSR) measurements from the literature proved the revised model an optimal one. Furthermore, using an ST, ignition delay times (IDTs) for the 3-pentanol/air mixtures were measured spanning a temperature range of 920−1450 K, pressures of 6, 10, and 20 bar, and equivalence ratios of 0.5, 1.0, and 1.5. Generally, IDTs decrease with increasing temperature and reflected shock pressure. Improved predictions to present experimental data were obtained by using the revised model as compared with the Carbonnier model. Finally, sensitivity analysis was conducted using the revised model to gain an in-depth comprehension of the 3-pentanol autoignition.
