Description

Vorkammerdieselmaschine nach Patent 6084%9, bei welcher der gesamte Brennstoff in die Vorkammer eingespritzt wird Die Erfindung bezieht sich auf eine Weiter- bildung und Verbesserung einer Vorkaminer- diesehnaschine nach #dem Hauptpatent (1o84;9, bei welcher der gesamte Brennstoff in die \-orkanimer eingespritzt wird, welche finit dem Haupthrennraum durch einen lsanal verbunden ist. in dem ein mit eineng Kern- stück versehenes Einsatzstück befestigt ist. in dein verengte Durchtrittsöttnungen vor- gesehen sind, welche in einen zun<iclist er- weiterten und sich dann gegen die Austritts- iittntuig in den Hauptbrennraum wieder ver- engenden - Ringkanal münden, so da13 der \-orkammerinhalt auf seinem Wege in den ldauptbrennrauin einer mehrfachen Drosse- ittng unterworfen wird. Die Erfindung besteht im wesentlichen darin, daß die den Ringkanal und die mittlere Austrittsöffnung bildenden Wandungel des t?insatzstiickes und die des Kernstückes zur AustrhisöMmng hin stetig so verlaufen, (1a13 der Vorkaminerinhalt durch den so gebildeten (liisenartig zum Austritt sich veriiingenden Rinälcanal möglichst wider- standslos ohne scharfe Umlenkungen aus- treten kann. Es sind @-orkarnnierlnascitinen bekannt. bei denen die Vorkammer durch einen der Brennstoffdüse gegenüberliegenden trichter- förmig sich verengenden, offenen Durch- strönil:<irial mit dem Hauptbrennrauni ver- hunden ist.
