Authors Abstract
Content
Analysis to clarify the influence of diesel nozzle hole specifications on HC emission is performed by using a single cylinder engine. The total nozzle hole area and the number of holes are the investigation parameters. The experimental results show that HC emission under low-load condition becomes higher with not only the increase of the total nozzle hole area but also the decrease of it. The reason for the increase of HC emission with small hole area is that the longer spray tip penetration of the pilot injection accelerates the spray diffusion in the cylinder, and the over-lean fuel-air mixture areas become easily formed.
