mtima injini dizilo ndi mafuta jekeseni mpope, deliverying mafuta kukhala kayimbidwe kotani kapena nthawi yomwe kupanga bwinobwino akuthamanga wa engine.At nthawi yomweyo, komanso kuchepetsa mafuta kuchuluka kupeza mphamvu required.While mu injini mafuta , ntchito jekeseni mpope uli fulumizitsa ndi system.So poyatsira ngati pali probem mu mpope mafuta, m'pofunika kufufuza psinjika, mafuta, ndi spark.Because palibe dongosolo poyatsira mu engine.Comparing dizilo ndi injini mafuta, injini dizilo ali ndi mwayi wa chifukwa cha bwino mafuta injection.Today China Balin mbali Bzalani, ndi wokonza lonse magawo wamba njanji & mbali dizilo jekeseni, kukuwonetsani mmene jekeseni mpope ntchito. Okhala pakati-jekeseni (kugwedezeka) mapampu Mu 1890s ndi mapampu woyamba kugwiritsa ntchito plungers kukakamiza metered mafuta m'chipinda kuyaka anali developed.Later mu 1927, misa limapanga helix womwe okhala pakati mpope anali anayambitsa ndi BOSCH.The mapampu, limatchedwa mapampu kugwedezeka, zikuwoneka ngati Bosch P7100 (P-mpope) pa '94 kuti '98 Dodge Ram 5.9L Cummins engines.Meanwhile iwo anamanga ku osiyana mpope ndi plunger mayunitsi chikugwirizana okhala pakati, chimodzi pa cylinder.They adamulowetsa ndi kamera, ndiwo umakaniko olumikizidwa kwa engine.Although sali kuti kudziŵa za dongosolo makina ankalamulira, mapampu adakali ndi ntchito ya zimasiyana timing.Inline jekeseni mapampu kuyang'ana ngati okhala pakati mini engines.It anapulumutsa 3,000-5,000 psi a kuthamanga jekeseni kwa oyambirira mini mapampu okhala pakati jekeseni pamene 18,000 psi a kuthamanga kwa anthu atsopano, Bosch P7100 imene tikhoza kupeza mu '94 kuti '981/2 Cummins injini. Wogulitsa (makina) jekeseni mapampu pali njira imodzi yokha mafuta metering plunger mu pump.Similar wogulitsa jekeseni kwa wogulitsa ntchito mfundo pa injini mafuta, hayidiroliki ndi chikugwirizana ndi madoko osiyanasiyana pa wogulitsa mutu kupyolera kupota rotor.This makina jekeseni mpope ali ndi mwayi kuti akatemera onse a mafuta ndi chimodzimodzi zomwe kupanga ang'onoang'ono chonse package.Comparing kuti mapampu ndi okhala pakati, ubwino wake wina kuti ali zochepa avundulidwe parts.Let titenge makina makina mapampu (Stanadyne DB2 ndi Bosch VE ) chifukwa example.The kuthamanga 6.700 psi amapangidwa ndi Stanadyne DB2 ndi 17,000 psi ndi Bosch VE. Chitsanzo china ndi amagetsi makina mpope ngati Bosch VP44.It akhoza kupanga 23,000 psi pressure.Even kuyerekeza kuti mapampu latsopano wamba njanji CP3, ifenso akanakhoza kunena ndi pump.Because ophunzira si yekha akanakhoza kulenga kuthamanga, komanso kulamulira nthawi ndi kuchuluka kwa mafuta kwa injini. Common-Sitima Yapamtunda jakisoni wamba njanji mafuta jekeseni, mpope mulibe chabwino kwambiri kusankha pamene mafuta izo pressurizes kamakhala anakamba ndi zomwe quantity.For Mwachitsanzo, CP3 mpope amalandira mafuta kuchokera mafuta tank.Then limagwiritsa ntchito zozungulira -piston kapangidwe kuonjezera kuthamanga immensely.After kuti, chotchinga wamba, kwenikweni ndi accumulator kwa injectors, pemphani ankamupatsa pressurized fuel.The injectors kutenga kuchokera kumeneko. Unit Injectors oyambirira akatswiri dizilo kuti nthawi kupeza mavuto amapangidwa mu mizere kulumikiza jekeseni mpope kwa injector.So mafuta mu 1905, Carl Weidman anamuchotsa iwo ndi kuongola jekeseni mpope ndi injector. Unit injector ndi yaying'ono mafuta jekeseni kamangidwe imene mpope plunger amalenga kuthamanga ndi mphamvu mawotchi ntchito ndi injini. The plunger ndipo injector analinso mu wagawo amene ntchito ndi kupulumutsa kutsitsi mafuta m'chipinda kuyaka. Ife tikhoza kupeza unit injector ntchito ambiri kuti Volkswagens ndi injini lalikulu dizilo.
