Comparative Study of Combustion, Performance and Emission Characteristics of Hydrotreated Vegetable Oil–Biobutanol Fuel Blends and Diesel Fuel on a CI Engine

Abstract

This article is a study of Hydrotreated Vegetable Oil and Butanol Fuel blends, which are mixed in three different proportions (HVOB5, HVOB10 and HVOB20), and the comparison of their combustion (in-cylinder pressure, pressure rise and ROHR), performance (fuel consumption, BSFC and BTE) and emission (CO2, NOX, HC and Smoke) characteristics with those of fossil diesel fuel. In the wake of finding an alternative fuel that requires little to zero modifications to the existing IC engines, it is necessary to account for the necessity of matching the efficiency of conventional fuels as well as greatly reducing its exhaust emissions. As a result of transesterification, HVO is found to have better stability and higher CN compared to other biofuels. It is termed a “renewable diesel” due to its ability to reduce emissions while maintaining efficiency. HVO as a fuel has higher cost efficiency, and for a more stable oxygen content in the fuel, an alcohol substitute is needed. Butanol, which has a considerable advantage over other alcohols due to its higher density, viscosity and CN, is selected. HVOB5 and HVOB10 are found to match diesel fuel in terms of fuel consumption while having a ~1% lesser efficiency. In terms of emissions, all the fuel mixtures including HVO100 are found to have ~4–5% lesser CO2, ~10–15% lesser NOX and a ~25–45% reduction in smoke levels.

The Influence of N-Butanol Addition in Gasoline on the Combustion in the Spark Ignition Engine

“…Currently, because ethanol is used in blends with gasoline on a large scale, marketed under the name of gasohol, many studies have investigated its use in internal combustion engines. Today, due to its good combustion properties, butanol can be a viable alternative fuel for internal combustion engines, for diesel engines [3,4] and for spark ignition engines [5,6]. Butanol can be blended with diesel fuel or with biodiesel; the amelioration of the biodiesel's combustion properties at butanol use can assure the improvement of the diesel engine operation [3,4].…”

For example, Lapuerta et al [5] used renewable normal butanol, n-butanol, to replace the ethanol in blends with gasoline in order to eliminate the disadvantages of ethanol use, like hydroscopic issues, in the gasohol fuel.…”

Determination of the Octane Number of Automotive Gasolines by Ftir Spectrometry With Chemometrics

“…The issue of motor fuel quality is currently a carefully monitored area (Gardyński and Kałdonek, 2020;Mikulski et al, 2022;Rayapureddy et al, 2022). The increase in motorization and progress in the development of power units require high quality fuels without undesirable additives while maintaining the prescribed parameters and quality indicators (Kamiński et al, 2021).…”

Recognizing Significant Components of Electrical Waveforms of Actuators Operated by Vehicle Controllers

“…The control parameters of internal combustion engine power systems have a significant impact on their operation. Appropriate adjustment of the parameters of the gasoline and gas supply control algorithm affects the emission of toxic components of the exhaust gas [ 11 , 12 , 13 ], and also affects the dynamic parameters of the car [ 14 , 15 , 16 ]. Research on the selection of injection parameters and optimization of the EGR of an engine fueled with a biofuel admixture is presented in [ 17 ].…”
