“…Bioethanol, 1-propanol, and 1-butanol have been used in the energy industry as additives of biodiesel. In addition, long-chain 1-alcohols (1-pentanol, 1-hexanol, 1-heptanol , ) when blended with biodiesel improve the physical properties of the fuel and modify the NO x emissions. , Also, it has been found , that mixtures of 2-octanol with biodiesel have adequate spray characteristics in the injection process in a diesel engine. Another application of alcohols is their use as reagents in the synthesis of branched esters .…”

In this work, we present new density measurements of benzyl alcohol and 1-heptanol from 283.15 to 363.15 K up to 65 MPa and ±2-octanol from 283.15 to 358.15 K up to 50 MPa. The density was obtained using a vibrating tube densimeter employing the Forced Path Mechanical Calibration method. The combined standard density uncertainty is 0.00035 g•cm −3 for benzyl alcohol and 1-heptanol, while for ±2-octanol (racemic mixture), it is 0.00045 g•cm −3 . The density data are correlated with a multiparametric equation of state explicit in the compressibility factor. We have correlated the density with the equation of state within an average absolute percentage deviation of (0.058, 0.085, and 0.077) % for benzyl alcohol, ±2-octanol, and 1-heptanol, respectively. Isobaric expansibility and isothermal compressibility are calculated from the multiparametric equation within an average absolute percentage deviation of 6% from values reported in the literature.

The use of renewable fuels for internal combustion engines marks a significant stride towards sustainability in transportation and power generation. Ensuring the compatibility of these fuels with existing diesel engines and infrastructure is paramount for a smooth transition. Diesel engines ca-pable of harnessing the advantages of alternative fuels without extensive modifications offer a pragmatic approach to sustainable power for vehicles and industries. This article investigates the impact of carbon neutral renewable fuel types (HVOs and biodiesel) on the operation of the high-pressure injection pump, focusing on rotational speed and delivery pressure as key parame-ters. Investigations, based on pump operating cycle analysis and volumetric efficiency measure-ments, reveals that while speed dependence is moderate, fuel type significantly influences pump performance. Hydrogenated carbon-neutral fluids (HVOs) demonstrate adequate capabilities compared to conventional fossil fuels, offering promising prospects for reducing environmental impact. The findings underscore the importance of considering fuel properties, particularly com-pressibility modulus. These insights provide valuable guidance for the advancement of sustainable transportation and industrial systems.

The use of renewable fuels for internal combustion engines marks a significant stride towards sustainability in transportation and power generation. Ensuring the compatibility of these fuels with existing diesel engines and infrastructure is paramount for a smooth transition. Diesel engines capable of harnessing the advantages of alternative fuels without extensive modifications offer a pragmatic approach to sustainable power for vehicles and industries. This article investigates the impact of carbon-neutral renewable fuel types (hydrogenated vegetable oils, or HVOs, and biodiesel) on the operation of a high-pressure injection pump, focusing on rotational speed and delivery pressure as key parameters. Our investigation, based on pump operating cycle analysis and volumetric efficiency measurements, aimed to investigate to what extent shaft speed and fuel type influence pump performance. Hydrogenated carbon-neutral fluids (HVOs) demonstrate adequate hydraulic capabilities compared to conventional fossil fuels. The findings underscore that while the fluids under consideration vary in viscosity and compressibility modulus, it is the compressibility modulus that predominantly affects the pump’s operation cycle. Diesel (fossil) fluid exhibits intermediate characteristics compared to hydrogenated fossil diesel fluids and biodiesel. The differences in terms of volumetric efficiency are finally reported, showing that hydrogenated carbon-neutral fluids do not significantly hinder the pump’s flow rate transfer capability.
