6. Both microscopic and macroscopic spray properties influence
the atomization quality of a certain fuel. There is a trade-off
between smaller droplet size and larger spray volume as they
both are determined by the properties of the fuel. The renewable
diesel stands out among the biofuels by showing smaller droplet
sizes (SMD, Dv10, Dv50, and Dv 90) than diesel. Using jet fuel in
diesel engines might yield better atomization due to its small
droplet size and similar spray volume to diesel under different
injection pressures.
