“…Although butanol is not suitable as a direct diesel replacement, the use of butanol as a significant component of diesel fuel has been explored in detail. Blends of 20 and 40% butanol in diesel fuel have recently been evaluated in a commercial diesel engine 37. The cetane numbers of these blends were determined to be 38.6 and 35.2, respectively.…”

OVERVIEW: The development of innovative methods to efficiently convert biomass to fuels and industrial chemicals is one of the grand challenges of the current age. n-Butanol is a versatile and sustainable platform chemical that can be produced from a variety of waste biomass sources. The emergence of new technologies for the production of fuels and chemicals from butanol will allow it to be a significant component of a necessarily dynamic and multifaceted solution to the current global energy crisis.IMPACT: The production of butanol from biomass and its utilization as a precursor to a diverse set of fuel products has the potential to reduce petroleum use worldwide. In concert with other emerging renewable technologies, significant reductions in greenhouse gas emissions may be realized. The rapid incorporation of renewables into the world fuel supply may also help to offset predicted increases in transportation fuel prices as the supply of oil declines. APPLICATIONS: Recent work has shown that butanol is a potential gasoline replacement that can also be blended in significant quantities with conventional diesel fuel. These efforts have transitioned to research focused on the development of viable methods for the production of an array of oxygenated and fully saturated jet and diesel fuels from butanol. The technologies discussed in this paper will help drive the commercialization and utilization of a spectrum of butanol based sustainable fuels that can supplement and partially displace conventional petroleum derived fuels.

“…The results showed that the THC of 20% n-butanol fuel is higher than that of diesel fuel, mainly because of the decrease of the cetane number of n-butanol-diesel fuel blends. Studies by López, Tutak, and others [2,[13][14][15][16][17][18] have also shown that the cetane number has a significant effect on HC emissions.Further research has indicated that the main cause of the change in HC emissions is the latent heat of vaporization and the cetane number of the fuel effects on the combustion temperature and combustion duration during the combustion process. Atmanli [7] conducted a studies on pure diesel, diesel-hazelnut oil-n-butanol blended fuel, diesel-hazelnut oil-1-pentanol blended fuel, and EHN in a four-cylinder, heavy-duty diesel engine.…”

Experimental Study of the Effect of Intake Oxygen Concentration on Engine Combustion Process and Hydrocarbon Emissions with N-Butanol-Diesel Blended Fuel

This paper summarizes a study based on a modified, light, single-cylinder diesel engine and the effects of the physicochemical properties for n-butanol-diesel blended fuel on the combustion process and hydrocarbon (HC) emissions in the intake at a medium speed and moderate load in, an oxygen-rich environment (Coxy = 20.9-16%), an oxygen-medium environment (Coxy = 16-12%), and an oxygen-poor environment (Coxy = 12-9%). The results show that the ignition delay period is the main factor affecting the combustion process and it has a decisive influence on HC emissions. In an oxygen-medium environment, combustion duration affected by the cetane number is the main reason for the difference in HC emissions between neat diesel fuel (B00) and diesel/n-butanol blended fuel (B20), and its influence increases as the intake oxygen concentration decreases. In an oxygen-poor environment, in-cylinder combustion temperature affected by the latent heat of vaporization is the main reason for the difference in HC emissions between B00 and B20 fuels, and its influence increases as the intake oxygen concentration decreases. By comparing B20 fuel with diesel/n-butanol/2-ethylhexyl nitrate blended fuel (B20 + EHN), the difference in the ignition delay period caused by the difference in the cetane number is the main reason for the difference in HC emissions between B20 and B20 + EHN fuels in oxygen-poor environment, and the effect of this influencing factor gradually increases as the intake oxygen concentration decreases.Energies 2019, 12, 1310 2 of 17 turbocharged diesel engine. The results showed that the addition of n-butanol produces more HC emissions as compared with the pure diesel because of the slow evaporation and the high latent heat of vaporization of n-butanol blends over a 25% load at 3000 r/min. Rajesh Kumar et al. [4] studied the effects of the mixing iso-butanol, n-pentanol, n-hexanol, and n-octanol with diesel on the engine performance of a single-cylinder, four-stroke, naturally aspirated diesel engine. The results showed that the high HC emissions of iso-butanol-diesel blends was attributed to the dominative effect of the latent heat of evaporation over its cetane number. Using a turbocharged in-cylinder direct injection diesel engine, Ileri [5] studied the influence of adding 2-ethylhexyl nitrate (EHN) on the combustion and emission of a diesel-sunflower, oil-n-butanol blended fuel and diesel-sunflower, oil-1-pentanol blended fuel. The test results showed that, at all engine loads, the higher latent heat of vaporization of n-butanol and 1-pentanol leads to an increase in HC emissions compared to diesel. Armas et al. [6] investigated pollutant emissions from the New European Driving Cycle (NEDC) using ethanol-and butanol-diesel blends. The result showed that the latent heat of vaporization is an important factor in HC emissions, but the high combustion temperatures during the development of NEDC weakened the effect of the latent heat of vaporization as compared with the combustion in cold engine conditions.

The characteristics of combustion, emissions, and thermal efficiency of a diesel engine with direct injection (DI) neat n-butanol were investigated. The engine ran at a load of 6.5–8.0 bar indicated mean effective pressure (IMEP) at 1500 rpm engine speed and the injection pressure was controlled to 900 bar. The intake boost pressure, injection timing, and EGR rate were adjusted to investigate the engine performance. The tests demonstrated that neat n-butanol had the potential to achieve ultralow emissions. However, challenges related to reducing the pressure rise rate and improving the ignition controllability were identified.
