- Summary:
- The increasingly stringent targets for the automotive industry towards sustainability are faced not only with the improvement of engine efficiency, but also with a growing research about alternative, synthetic and CO2-neutral fuels. These fuels are produced exploiting renewable energy sources, thus being CO2-neutral, and aim to be able to reduce a significant amount of engine emissions, especially particulate matter (PM) and total hydrocarbon (THC).The objective of this work is to study the behaviour and the potential of an eFuel developed by Porsche, called POSYN (POrscheSYNthetic) and to compare it to a standard gasoline. This investigation is carried out starting from a thorough spray analysis, including high speed video imaging along with injected droplet size and velocity measurements by means of Phase Doppler Anemometry (PDA). Furthermore, an experimental campaign with a single cylinder engine performed by Porsche provided data about this eFuel effects on an engine in terms of performance and emissions. Two different fuels and two types of injectors, an A-Nozzle and a multi-hole injector, are taken into account in this work. The experimental investigations were supported by 3D-CFD simulations. The thermodynamic properties of the eFuel, after being experimentally measured, have been implemented in the CFD code for a precise reproduction of the fuel behaviour, and the data collected from the spray analysis and the test bench experimental campaign were used to tune the injection model for the POSYN-fuel in terms of its adoption in 3D-CFD engine simulations. A reliable model of the single cylinder engine test bench has been also developed to study the influence of the new synthetic fuel on mixture formation and combustion for different engine operating points. The results obtained from the simulations can be exploited to optimize the utilization of this eFuel for better engine performance
