Fuel Spray Behavior in a Small DI Diesel Engine: Effect of Combustion Chamber Geometry

Experimental Cells for Research Diesel Sprays

“…The camera was placed perpendicularly to the beam, having with this the advantage of taking images directly. This thermal engine unlike the one used by (Montjair et al, 2000) had completely transparent walls, which allowed a complete capture of the phenomena (injection-combustion). Furthermore, it required complex routines at the moment of doing any changes in the installations configuration.…”

Investigation of Cluster-Nozzle Concepts for Direct Injection Diesel Engines

“…A large diameter chamber is required to allow more free spray travel, achieving a better air-fuel mixing and reducing the wall impingement and therefore the soot formation [22,23]. For deep bowl geometries, it was reported that a bowl with a round re-entrant lip shape has about 20 percent longer spray path length than one without a re-entrant shape [24].…”

Study of spray impingement and a squish combustion system for diesel engines

“…Fortunately, recent research shows that proper impingement can improve the mixture formation [9,10]. Furthermore, it is an efficient method to guide the airflow inside the combustion chamber with the special piston cavity [11][12][13][14], to realize a favourable fuel/air mixture. In order to improve fuel/air mixture quality and reduce emissions, a new SISCS has been developed.…”
