“…This in turn gives the fuel enough time to mix in air and tends to reduce cylinder temperature. The reduction in the cylinder temperature results in the lower NOx and HC emissions with butanol added mixture than the normal diesel and diesel gasoline mixture [8]. The emission characteristics of NOx and HC for all the fuel blends are shown in figure 3 and figure 4 respectively.…”

“…Minguri Wei et al used D (diesel)/ gasoline (G)/ B (iso-butanol) blend in a four cylinder diesel engine at five different compositions and revealed that at low loads, 100% D and at high loads, 70% D -15% G -15% B were the optimum mixture concentrations for obtaining improved performance and reduced emissions [7]. Ashish Nayyar et al mixed n-butanol with diesel at different concentrations, used in a Diesel -Kirloskar (TV1) engine and observed that with the blends of 19.82% and 18.84% of butanol with diesel at part loads and full loads respectively, the efficiency increased by 5.54% and NOx reduced by 15.96% than normal diesel [8]. Md Nurun Nabi et al investigated the usage of neat diesel and diesel butanol blends in a Cummins 6 cylinder in-line engine under 13-mode European stationary cycle and declared that at 6% composition of butanol HC reduced by 36% and at the same time NOx increased by 6.6% than neat diesel [9].…”

Emissions have become an important parameter, playing an extensive role in the selection of engines. To find out the alternatives for petroleum based fuels owing to their continuous depletion and the increase in emission rates, research works are being carried out continuously. The prime objective of this work is to study the effects butanol additive to the diesel-gasoline mixture fuelled to a CI engine. The operation is carried out by mixing butanol with diesel-4% gasoline mixture at different proportions and the mixtures are used to run a single cylinder APEX 240PE kirloskar make engine at constant speed under a series of load conditions. The performance characteristics of the fuel mixture used is obtained and the concentration of emissions present in the exhaust has been determined using an Emission Analyzer. The mixture can be used as an alternative fuel in diesel engines, thereby producing reduced emission rates.

“…To accelerate this process and reduce costs, computational fluid dynamics (CFD) simulations are routinely used by manufacturers to evaluate, understand, and optimize FIE design and operation. Many numerical methods and approaches have been developed to simulate the performance of fuel injectors and provide insight into the physical processes taking place inside these systems [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Accurate simulation of the flow field within the FIE and phenomena observed further downstream (e.g., jet breakup and spray formation) is required to ensure their reliable predictive capability.…”

This study presents a pseudo-component method using the Perturbed-Chain Statistical Associating Fluid Theory to predict density, isothermal compressibility, and the volumetric thermal expansion coefficient (expansivity) of hydrocarbon mixtures and diesel and jet fuels. The model is not fit to experimental density data but is predictive to high temperatures and pressures using only two calculated or measured mixture properties as inputs: the number averaged molecular weight and hydrogen to carbon ratio. Mixtures are treated as a single pseudo-component; therefore binary interaction parameters are not needed. Density is predicted up to 470 K and 3,500 bar for hydrocarbon mixtures and fuels with 1% average mean absolute percent deviation (MAPD). Isothermal compressibility is predicted with 4% average MAPD for hydrocarbon mixtures and 9% for fuels. The volumetric thermal expansion coefficient is predicted with 7% average MAPD for hydrocarbon mixtures and 13% for fuels.

“…Modeling (Full Factorial design) and experimental investigations aiming at emissions reduction and engine performance were carried out by Nayyar et al (2017) testing n-butanol/diesel blends (10 to 25 vol%) on a small size, modified and variable compression ratio (VCR) diesel engine, operating at a constant speed of 1500 rpm and variable engine load (12, 16, 20 and 24 Nm). Butanol provided a significant reduction in emissions (59.56% in smoke and 15.96% in NO x ) and a slight improvement in engine efficiency (5.54% in thermal efficiency), with optimum results obtained at injection time of 23° CA BTDC / injection pressure of 210 bar and higher compression ratio of 18.5 and 19.5 for pure diesel and blends with 20 vol% of butanol, respectively.…”

The alternative use of butanol in blends with diesel has attracted the attention of many researchers worldwide for its possibility to overcome some barriers observed for other lower chain alcohols. Viscosity, volatility and ignition quality are critical characteristics of a fuel intended for use in compression ignition engines. In this paper, the kinematic viscosity, atmospheric distillation and cetane number of butanol/diesel blends in proportions of up to 30 mass% were determined and compared with Brazilian diesel specifications. Two types of diesel matrices 10 ppm (S10) and 500 ppm (S500) sulfur and two butanol isomers (n-and iso-butanol) were tested. Results showed that both kinematic viscosity and cetane number were reduced with the increase of the butanol content in blends. Butanol provided an intense increase of the blend volatility, resulting in pronounced effects on the distillation curve shape, in relation to that observed for pure diesel.
