VARIABILITY OF THE DIESEL FUEL SPRAY MICROSTRUCTURE DURING THE INJECTION INTO STAGNANT AIR BY A TYPICAL DIESEL ENGINE INJECTOR
Journal Title: Journal of Machine Construction and Maintenance - Year 2018, Vol 109, Issue 2
Abstract
The article presents the results of a study on the distribution of Sauter Mean Diameter (SMD) along the axis of an atomized diesel oil spray and changes in SMD occurring during the injection in selected cross-section of the spray. A piston fuel pump was used for atomization, while atomization quality measurements were made using a Malvern Spraytec particle analyzer. The results show that adopting averaged SMD values for the whole fuel spray charge does not reflect the actual range of droplet sizes in the area of highest volume concentration of droplets in a spray, i.e. the area having the greatest impact on the evaporation and combustion of fuel. It can be useful to designers of diesel engines and simulation of processes in combustion chamber.
