A better understanding of why and how pollutant emissions from compression ignition engines are produced is one of the strategies to reduce them, and to achieve this it is important to understand what happens in the fuel injection inside the combustion chamber and in the combustion process. Experimentally, it is difficult to analyse the fuel spray right at the initial moments when it enters the combustion chamber due to its high velocity. These initial moments of the fuel spray affect its complete development and, consequently, the combustion process inside the chamber. This fact has motivated the approach of this work, in which a parametric study of the spray penetration as a function of variables that can be measured has been proposed. The purpose of this model is to understand which variables of the injection system significantly affect the spray penetration in the initial instants and how they affect it. This study was carried out using diesel and serves as a reference framework for similar studies using pure or blended sustainable advanced fuels. A computational fluid dynamics (CFD) model that determines the spray penetration at initial instants under different injection pressures and nozzle hole diameters is presented in this work. To tune the model, experiments were carried out on an optical engine. The modelled and experimental results exceed 94.8% agreement in all cases studied.

This work presents a computational study about the effect of different fossil fuels (Diesel and GTL) and renewable (Farnesane and Biodiesel) on the characteristics of the nozzle fuel internal flow (speed flow, cavitation, mass flow rate and discharge coefficient). This investigation was focused on the pass of fuel from the volume around the tip of the injector needle to the nozzle holes. Several engine-operating conditions, characteristic of urban driving conditions, were tested. These conditions, characterized by their injection pressure and injection timing as well as the experimental rates of fuel injected, were simulated with all mentioned fuels. Solenoid operated seven holes injector, 0.15 mm orifice diameter was used. Results show the effect of fuel origin on the internal flow along the nozzle orifice of the injector. Among the results obtained are the following: at medium load the effect of the needle lift on the cavitation generation is more significant than the fluid circulation velocity and fuel origin impacts as follows: Biodiesel > GTL > Farnesane > Diesel; while, at medium or high engine speed, an increase of engine load causes a decrease of cavitation generation and fuel origin impacts as follows: Diesel >> Farnesane > GTL > Biodiesel.

The compendium of phase change enthalpies published in two parts in 2016 is updated to include new fusion, vaporization, and sublimation enthalpies published in the interim and includes some earlier data either previously missed or were unavailable. Also included in this article is an update of recent studies on the phase change enthalpies of polyaromatic hydrocarbons. Group values previously evaluated to adjust for temperature of phase changes are updated for aromatic compounds in view of recent experimental data. The new group parameters have been evaluated on the basis of their consistency in providing appropriate temperature adjustments to phase change enthalpies at T = 298 K as evaluated by a thermochemical cycle. This evaluation provides transition temperatures and about 1000 heats of fusion, 700 heats of vaporization, 500 heats of sublimation, and about 50 other heats of transitions for about 30 polyaromatic hydrocarbons and 1100 other molecules consisting of C1-C57 organic compunds, organometallics, inorganic compounds, and ionic liquids taken from about 900 references.
