ngakau o te pūkaha diesel ko te papu wahie i werohia, deliverying wahie ki te mau tonu i te he manawataki wā ranei te pai rere o te engine.At te wa taua e hanga, reira whakahaere hoki te rahinga wahie ki te riro i te required.While mana i roto i te pūkaha penehīni , ko mahi o te papu te werohanga i roto i te kātere me te system.So pātīmata ki reira he tetahi probem i te papu penehīni, he mea e tika ana ki te tirohia kōpeketanga, wahie, a spark.Because reira he kore pūnaha pātīmata i roto i te engine.Comparing diesel ki te pūkaha penehīni, te pūkaha diesel e te painga o te hua tika o te pai wahie injection.Today China Balin Parts Plant, he kaihanga ao mō ngā wāhanga tereina noa & wāhanga werohia diesel, ka whakaatu ki a koe e founga te mahi i werohia papu. Rōraina-werohia (takiri) papua I roto i 1890s te papua tuatahi ki te whakamahi i plungers ki faahepo wahie metered ki te ruma ngingiha ko developed.Later i 1927, i whakaurua hoki te rōraina papu helix-te mana papatipu-hua e papua BOSCH.The, ētahi wā i huaina papua takiri, titiro rite Bosch P7100 (P-papu) i runga i '94 ki '98 Dodge Rame 5.9L Cummins engines.Meanwhile hanga ratou i papu me plunger wae motuhake hono rōrārangi, tetahi ia cylinder.They e whakahohe i te haere, i te mea mihini hono ki te engine.Although kahore e ratou ki te tino ihi o te pūnaha rorohiko whakahaeretia, i tonu nga papua te mahi o rerekē timing.Inline papua werohia titiro rite rōraina paku tukua engines.It 3,000-5,000 PSI o te pēhanga werohanga mo te tuatahi paku papua werohanga rōraina i 18,000 PSI o te pēhanga mo nga mea hou, Bosch P7100 nei i kitea e matou i roto i '94 ki '981/2 Cummins engines. Distributor (Rotary) Werohanga papua He kotahi anake plunger wahie-Mita i roto i te pump.Similar distributor werohanga ki te distributor mahi parau tumu i runga i te pūkaha penehīni, hono te waipēhi te ki ngā tauranga rerekē i runga i te matenga distributor i roto i te rotor.This pōtaka werohia hurihuri papu e te painga e te hunga rite nga matā katoa o wahie te taua he package.Comparing iti whānui e hanga ki te papua rōraina, ona painga tetahi he e kua reira tango iti pokarekarenga parts.Let o papua hurihuri aunoa (Stanadyne DB2 me te Bosch VE ) hoki example.The pēhanga hua 6,700 PSI e Stanadyne DB2 me 17,000 PSI e Bosch VE. Ko tētahi atu tauira ko te papu hurihuri hiko rite Bosch VP44.It taea te whakaputa 23,000 pressure.Even PSI whakatairite ki papua noa-rail CP3 hou, i taea e hoki mea tatou ko reira te pump.Because kakama reira kihai anake i taea te waihanga te pēhanga, engari ano hoki te whakahaere i te wā, me te rahinga o te wahie tukua ki te pūkaha. Common-Rail Werohanga Ki noa-rail wahie werohia, e kore e te papu i te nui e tika ki te whakatau ka te wahie pressurizes reira te tangata e tukua, me te i te mea quantity.For tauira, e tango te papu CP3 wahie i te wahie tank.Then whakamahia e te reira toropā hoahoa -piston ki te whakapiki ake i te pēhanga immensely.After e, te rail noa, fele he accumulator mo nga injectors, te tiki i tango i runga i tenei injectors fuel.The tino pressurized i reira. Unit Injectors te Engineers diesel wawe i kitea tonu nga raruraru e hua i roto i te rārangi honotanga te papu werohanga ki te injector.So wahie i roto i 1905, I whakakahoretia Carl Weidman o ratou na roto i te heru i te papu i werohia me te injector. Ko te injector wae ko te hoahoa wahie i werohia kiato i roto i nei hanga te plunger papu pēhanga tiketike e te ope aunoa tono e te pūkaha. Ko te plunger me injector whakakotahitanga ki tetahi wae nei mahi ko ki te whakaora i te rehu wahie ki te ruma ngingiha. taea e kitea e tatou te tono i te injector wae nuitia ki Volkswagens me engines diesel nui.
