Engine & Performance

Salam,

disini aku nak kongsikan sedikit sebanyak pasal enjin yg mendiami enjin bay aku skarang. Untuk pengetahuan berpandukan geran, enjin kereta aku telah ditukar dr (...... nanti aku edit balik, lupa lak code enjin dia....) kepada enjin jenis ZC. ZC?? apekebendanye tuh? meh refer info aku cilok dr wikipedia...

ZC(similar to D15Z4, D16Z6, D16A1, D16A3, D16A6, D16A8, D16A9 and D16Z5 engines)

A few D-series variants are labelled "ZC" (usually JDM), but they are not truly a different series.

There are both SOHC and DOHC ZC engines.

The non-VTEC SOHC ZC is similar to the D15Z4 and D16A6 engine, but with more aggressive cam timing.

The VTEC SOHC ZC is identical to the D16Z6.

The DOHC ZC is similar to the D16A1, D16A3, D16A8, D16A9 and D16Z5 engines.

• • 2nd Gen ZC (rarest)

Identified by: Internal coil, large distributor, single butterfly TB mounted on slight angle forward, bolts on top of cam cover, black cam cover, large cam pulleys. +7cc PM7 pistons, 43 cc Pent roof combustion chamber. As a ZC appeared in JDM facelift AV bodied Integra Si did not appear in Civic or CR-X, rarest ZC only produced for less than one year. D-series version D16A1 '88-'89 (sometimes +7cc P29 pistons)

Review skit pasal enjin nie...

Fuel Consumption
enjin aku nie 1.6 sohc vtec auto. so, what r u expecting? auto bai... rasanye kalau main ngan saga aku nie gear 3 je (hehehe). tp seriusly aku ckp, apa yg aku perhatikan overall fuel consumpsion leh dpt untuk rm10 ~ 60kmh (bwk ilek2 dgn on aircond + lenjan2 skit hehe). kalau long distance lg layannn.. memang sep . pebarang nak laju tp minyak nak save!!

Respon Enjin
buat masa nie respon enjin utk cara bwk2 biase lg sedap dr wira auto 1.5 sohc mak aku (nie je perbandingan yg leh aku buat) dan lagi sedap kelisa auto adik aku (huhuhuhuhu). gear change mostly at 3000rpm (normal kot).

VTEC ON~!
terus terang aku katakanla aku pun tak tau bape vtec activate kt enjin nie. tp apa yg nyata bila kita floor pedal, enjin akan bunyi kuat skit... bila lebih je rpm 4000 dia akan rasa satu sentakan bersama bunyi jeritan (skit je) kereta jd ringan je perginye (mcm melayang2 pun ada). tgk speed meter, boleh tahan naik.

aku pernah test dkt hiway, suddenly floor pedal vtec ON, selambe je leh cecah 180kmh. mcm tak caye je. dan pomen yg bikin kete nie test malam sebelum aku amik kete nie ckp 200kmh dpt kt hiway kesas. hehehe. so far, aku lum berani nak lenjan tahap tu lg. lgpun tgk enjin lain mcm je, teppet pun berbunyik. aku rasa owner lama aku usik skit la.

minyak time vtec ON? mcm air beb... siyul tul. memang ada efek. beza jauh berbeza hehehehe...

anyway, tu je review aku untuk enjin nie, byk gile benda yg aku tak tau. nak mintak tolong org ajar pun, tanye pun takde respon. nak belajar sendiri kang ada yg sesat. ermmmm..... tp takpelah guna dulu apa yg ada. lgpun modal dh byk habis. nak tkr enjin?? lepas kawen la. tu je.

utk enjin nie paling kuat pun mungkin la aku tkr gearbox manual, masuk VAFCII ke tak pun masuk set skunk2 untuk enjin nie (wan cipan supercas DRAX dah ada resepi hehehe) or just pump in b18cR . setel!

k chow..... byk lak bebel malam2 nie, korang bukan baca pun. suka tgk gambar je, tui tak hehehe.
