Eddy chamber arrangement for diesel engine - involves injection nozzle and incandescent plug with accommodation hole receiving active end area of plug in groove-shaped end part

摘要

The free end (16) of the incandescent plug (13) extends into an upper chamber area (2) running with a part of its periphery in a groove-shaped end area (17) of the accommodation hole (12) open laterally to the eddy chamber (5). The axis (15) of the incandescent plug runs virtually tangentially to the eddy chamber. The end area of the plug narrows and the volume of the injection channel (18) is at most two per cent of the volume of the total eddy chamber. Between a further wall area (8) of the eddy chamber insert (3) and a connecting channel (7) an even floor wall area (9) extends with a cross-sectional width which is at least 23 percent of the dia. of the upper eddy chamber area (2). ADVANTAGE - Improves the redn. of particle emission.
