kalu ada meter RPM (tachometer), guna tu je laa sbg referal utk speed......... normally pd masa crusing, 3000 rpm = 110km/j (5th gear utk keta manual)........

mmg le. lgpon speedometer aku mmg tadek masalah benonye. function je. yg jd masalah kat aku tu sbb odometer dia rosak la. susah aku nak tau bila aku patut pi servis keta. tu je. sbb tu aku pi tko meter.....semata2 nak bg odometer tu idup.

ha ni y aku nk tanye pasal neh ni.. nk tau standard sebenar. . brp RPM vs km/j utk, 60km/j / 80 / 100 / 120 ???
kalo ada jadual lg bagus. hehe

aku rasa byk benda kene konsider la rpm ni. akan berubah ikut jenis kereta la pastinye. sbb aku rasa tiap model keta...yg guna enjin berlainan akan mempunyai gear ratio yg berbeza. dan....saiz tayar pon mengubah kaitan rpm ngan laju.

ikut yg aku tau la kan. tp mmg ada cara nak kira2 suma tu. agak complicated....

aku cuba wat formula sat td..... mungkin ada silap tp pada aku betul la tuh. kalo ada otai yg pasan tolong betulkan.

Laju keta = Ukur lilit tayar x [ RPM / ( engine ratio x axle ratio ) ] x ( 1jam / 1 km )

1 km = 39370.07874 inch
1 jam = 60 min

katakan lah.....   

radius tayar = 10 inch
RPM = 6000
Engine ratio = 0.75
Axle ratio = 3.5

Laju kereta
= (2 x 3.142 x 10 inch) x [6000/(0.75 x 3.5)] x (60 min / 39370.07874 inch)
= 218.8987 km/jam

Ringkasnye...

Laju kereta = 0.009576816(radius tayar dlm inch)(RPM) / [(gear ratio)(axle ratio)]

sekian terima kasih

pe lagi mod2 yg dikasihi....bagi le anugerah.hehe

nie bergantung pada gear & CC keta ko.... kalu 1.3 / 1.5 punya pd RPM 3k dgn gear 5 sekitar 100-110km/j.......

setahu aku cc kereta tadek kaitan langsung ngan rpm dan laju. cc cuma berkait power. perbezaan laju ngan rpm bergantung kepada nisbah gear enjin, nisbah gear drive shaft ke tayar dan jejari tayar je.


kalo aku salah tolong betulkan supaya aku tak sesat seumur hidup.

sy.. penah hadapi masalah mcm ne... odometer x bergerak@... statik jea... jarum speedometer oky...
sy p lh tanya kat kedai wiring kat seremban.. tokey kedai 2.. mitak kita tukar speedometer seketul... dlm rm 190+rm20 upah.. rs mcm mahal.. x kn x leh repair kot... sbp nya.. keta kancil yg lampu bulat.. ada hadapi masalah odometer x appear (kancil lampu bulat guna odometer elektronik) boleh jea repair dlm RM35.. so sy cr lh kedai wiring yg lain...
akhirnya.. jumpa lah.. satu kedai wiring kat pekan kemayan, pahang.. border dgn negeri sembilan.. dlm 30km dr bandar Bahau. nama kedai 2.. hard auto wiring... kena tukar meter gear aja.. yg mcm gigi gear.. kosnya.. meter gear rm28+upah rm20...
allhamdulilah... dh selesai masalah odometer x bergerak....

kalau duk KL, jauhnye nak sanun bro... haha
apa2pun memang terbaik la pomen hang tu...memang rajin dia membaraikan meter tu..
yg sbenarnya..memang boleh repair, tapi kalau kat bandar2 ni pomen malas nak buat benda2 kecik..
depa lebih suka tukar seketul ja....senang keje katanya....lagipun boleh masuk lebih sket...kot
