- saya ada dgr cerita kalau carb(jalan dekat kurang makan minyak... kalau efi jalan jauh jimat... betul ka tu
macam mana pun carburator memang lebih makan minyak. kalau kamu kira sensor yang terdapat di efi memang banyak, tapi adakah betul-betul berguna? yes of course. seperti water temperature sensor, signal akan send ke ecu bahawa engine sejuk. kalau engine sejuk, ecu akan control injector supaya dapat rich mixture, supaya pagi sejuk senang start engine, ataupun control cold start injector. kalau sudah panas, injector akan kurang kan semburan petrol. EFI ini lebih jimat minyak kalau cruising, around 80kmh atau 100kmh. dimana angin perlu daripada petrol, lean mixture, injector akan sembur sedikit sahaja. semuanya control by ecu, sensor akan beri signal ke ecu. |

Otai2 sioloon tlg jelaskn.. ya ketinggian memang jejaskan, walaupun udara sejuk, tapi oksigen semakin nipis. carburator ini mekanikal control air fuel ratio, jadi kalau terlalu tinggi memang susah sudah tu. lain pula kalau efi, sensor dia akan beritahu kurang oksigen, ecu akan control itu air fuel ratio, jadi kuranglah masalah. |
