The droplet size distribution is critical for fuel efficiency and effective combustion development within compressed and spark ignition engines as this directly impacts the effective mixture preparation of the fuel in the engine.
In order for the engine to be fuel efficient you must achieve effective combustion. This is reliant upon the effective mixing preparation.
The drop size is critical for this parameter as it defines the specific surface area of the spray with the greater surface area resulting in more efficient mixing and as a result greater volumetric heat release rates and lower concentrations of exhaust emissions. The effective rate of heat and mass transfer is defined through the optimisation of the drop size of the injected fuel.
Oxford Lasers provide products and services to measure droplet size distribution to a variety of applications within the automotive sector.
