| injector atau alat suntikan bahan api ialah alat yg mnyuntik bhn api ke dlm kebuk pembakaran utk dicampur dgn udara n dinyalakn oleh percikan (spark) oleh palam pencucuh. ada 2 cara modifikasi thadap injector iaitu dgn menambah atau menukar injector. jika menambah injector, tempat yg plg sesuai utk dpasang adalh antara t/body n torbo@supercas@air filter. jika menukar injector, setiap injector asal dtanggalkn n injector baru dpasang. ingin sy tegaskn, modifikasi pd bahagian injector adalh berbaloi sekiranya enjin anda telah diubahsuai terutamany enjin bkuasa torbo atau enjin NA yg mampu rev dgn tinggi.
injector asal smestiny x dpt mnampung kperluan bhn api enjin yg telah diubahsuai. kapasiti injector bgantung kpd kuasa enjin, tekanan bhn api fuel pump n juga tekanan dari fuel regulator. lebih besar tekanan bhn api, lebih besar kapasiti injector yg dperlukan. jika tidak, enjin anda mgkin mngalami masalh 'lean' d mana air fuel ratio adalh kurang drp idle (14.7).
utk modifikasi penambahan injector (extra injector), ia hny dgunakan apabila anda mgunakn enjin yg dilaras pd boost yg tinggi. lazimny extra injector dpasang di mulut t/body n kawalanny dkawal mgunakan additional injector controller (AIC) atau dgn ecu yg boleh diprogram spenuhnya (standalone). ubahsuai sbegini smakin kurang popular kerana kapasiti injector yg lebih tinggi mudah ddapati.
jadi, bagaimana utk mngetahui kapasiti injector yg harus anda gunakan? kapasiti injector ini boleh dtentukan mlalui formula Injector Flow.Injector Flow = (Horsepower x BSFC) ÷ (No. of Cycle x Duty Cycle)BSFC bmaksud brake specific fuel consumption yg mnerangkan tahap keberkesanan enjin (engine efficiency). secara purata, BSFC bg enjin NA adalh 0.5 (50%) manakala bg enjin torbo atau supercas adalh 0.65 (65%). Duty Cyle pula mnunjukkan brp kali injector memancitkan bhn api. bg enjin 4 stroke, Duty Cycle adalh 0.8.
sbg cntoh, anda boleh mngira horsepower enjin anda dgn mgunakan psamaan:Power = 2π N T
N adalh rpm optimum enjin T adalh max torque enjincontohny jika enjin anda mpunyai 200hp (OTE), kiraannya adalh:Injector Flow = (200 x 0.4) ÷ (4 x 0.8) Injector Flow = 31.25 paun (1 injector)
utk menukar kpd cc, Injector Flow x 10.5 kapasiti injector (CC) = 31.25 x 10.5 = 328ccjadi, kapasiti minimum injector yg anda perlukan adalh 328cc.

| utk buang speed cut, ad bnyk cara... plg senang, pasang trus RSM(utk buang speed cut).. bila suda buang speed cut, fuel cut pn otomatik akan ilang.. utk kancil l2s, ad yg pkai fuel cut defencer (sambg dgn ecu asal), kos dlm rm150.. |

| bro keba..saya cuba kira injector standart utk enjin l2..
kalau salah tolong bagitau ya..stendet HP dlm 67HP macam tu kan? so..
(67 x 0.65)/(3 x 0.8)
(43.55) / (2.4)
= 18.15
18.15 x 10.5 = 190cc
betul ke? injector standart l2 190cc? |
