Chojambulira chamafuta chokhala ndi mbale ya orifice pafupi ndi potulukira. Chophimbacho chimakhala ndi malo oyamba ndi achiwiri omwe amatalikirana ndi mtunda wodziwikiratu kuchokera kwa wina ndi mzake ndi tsinde, mphuno yomwe imadutsa pamtunda wotalikirapo ndipo imaphatikizapo malo oyamba ndi malo achiwiri omwe amatalikirana kuchokera pamtunda woyamba. Gawo loyamba limaphatikizapo gawo loyamba lomwe lili ndi mawonekedwe oyambira omwe amalunjika koyambira kolowera kumtunda wautali. Pamwamba pachiwiri pali gawo lachiwiri lomwe lili ndi mawonekedwe achiwiri omwe amayang'ana mbali yachiwiri ya oblique kupita ku longitudinal axis. Injector yamafuta imakhala ndi nyumba yotalikirapo yotalikirapo. Nyumbayo imakhala ndi cholowera, potulukira ndi kanjira kamene kamayikidwa pakati pa cholowera ndi potulukira. Injector yamafuta imaphatikizansopo cholumikizira chamagetsi chomwe chili pafupi ndi cholowera, cholumikizira chamagetsi chophatikizira cholumikizira chamagetsi ndi cholumikizira chamagetsi chamagetsi, gulu la ma valve kuphatikiza membala wotseka ndi mpando wa valve, membala wotseka womwe umagwira ntchito kuti utseke mafuta otuluka munjira. malo oyamba komanso ogwiritsira ntchito kulola kuti mafuta azilowa mu mbale ya orifice pamalo achiwiri. Njira zingapo zopangira ma orifice okhala ndi ngodya mu pepala lachitsulo zimafotokozedwa momwe tsinde lopindika limatha kupangidwa kuchokera kumtunda wokhala ndi ngodya yakumanja. Mphepete mwa nyanja iliyonse imakhala ndi oblique axis yokhudzana ndi imodzi mwa malo oyambirira komanso yachiwiri ya pepala lachitsulo.
