NOZZLE SPRAY TIP

摘要

mechanical engineering; compression ignition internal combustion engines. SUBSTANCE: spiral grooves are made on inner surface of nozzle spray tip body. Spindle is provided with two thrust projections getting into spiral grooves of spray tip body. Moreover, head is made in lower part of spindle. Radial nozzle holes made in head body are located above spray tip body edge. Holes are connected through fuel feed channel with above-spindle space. Invention improves quality of fuel distribution over entire volume of combustion chamber at injection. EFFECT: reduced fuel consumption and improved ecological characteristics of engine. 2 dwg
