Almost smua kete skrg ni gune 4 stoke engine. Cume ade la certain2 kete yg gune engine len cam diesel (biase kete 4wd) n rotaty engine (aku tau RX-8 je yg pkai engine ni..huhu) Ni kalo budak meche bace xtau fakta ni mmg buang negara la...lol
Ok...mmndangkn byk kete pasal 4 stoke..kite cite 4 stoke la k. korg mst pnh dgr term2 cam V6, double over head cam, 3.0 liter...haaa...smua ni adelah spec enjin 2 la. Engine consist of 2 main part; engine block and head. Engine block la kat mane piston, fly wheel, connecting rod, crank shaft and sump located. Head plak letaknye intake valve, exhaust valve, cam shaft and spark plug. haaa..budak meche bace pning...jap aku cari gmbar jap....
Haaa...gmbar ni ssuai..siap lebel da. Tgk ar yg bhgn atas 2 la Head engine. Bhgn bwh lak Engine block. Tp gmbar ni xde sump...sump 2 adelah takungan minyak hitam kt bwh engine block. Minyak hitam gune dia sbgai pelincir la spye lebeh efficient dan enjin pon tahan lame. Minyak hitam ni akn di pam oleh oil pump n with high pressure dia akn distribute ke slruh bhgn enjin (yg bawah piston je k..sbb atas piston 2 da kire combustion area da...xleh campur ngn minyak hitam)
Ok..td ade ckp pasal V6 kan...ha...sbnrny V susunan piston2 iaitu dlm V shape. 6 plak maksudny ade 6 piston utk engine 2. Orait..standard engine ade 4 6 or 12 piston la. Aku pnh tgk kene jaguar 12 piston...mmg gile beb~~ (kancil aku je 3 piston...pelik2)... orait... standard orientation lak biasenye ade in-line, V or flat shape. yg ni aku xphm sgt lak ape effect dia kat efficiency...nnt aku tnye mmber aku...
Orait..cite 4 stroke kan..ni stroke2 n condition engine pd stroke 2:
1) Intake stroke : Intake valve open, exhaust valve close, Piston moving downward
2) Compression stroke: Both valve close, Piston moving upward (compress)
3) Combustion stroke: Both valve close, spark plug ignite just a moment b4 piston reach top dead end, Piston moving downward
4) Exhaust stroke: Exhaust valve open, piston moving upward
Haishh...budak meche xtau ni mmg wajib kene rejam smpai ****.
Orait..ape yg mngawal valve2 ni dr open n close ikut stroke n ape lak yg kawal spark plug spaye dia ignite on da rite time. Ape yg kawal spark plug timing is distributor...and yg kawal valve plak kite pggil dia camshaft. budak meche xpnh dgr cam mmg trok...xskolah punye org.haha..jgn mara...ko try ar search tenet sndri tgk camne camshaft 2 look like k. Camshaft ni driven by crankshaft yg ade kt bwh engine 2 (tgk gmbar blik) dan both shaft ni digabungkan oleh timing belt. Orait...biasenye camshaft ni akn di adjust pusing one-half dr crankshaft. So gear camshaft punye gear mst kecik skit la kan...Hurm...kt sini la dtg nye term2 pelik cam double over head cam. maksudnye...camshaft 2 letak nye dekat atas head. double plak maksudnye ade 2 camshaft yg mane utk setiap cylinder ade 2 intake valve and 2 exhaust valve. so masing2 camshaft akan control 1 intake valve and 1 exhaust valve. Xslh aku kete lame2 dia xpkai overhead cam. cam shaft dia letak kt bwh n dia xpkai timing belt pn. Xpnh tgk mende ni...kalo nk tau try la cari sndri...
K...mls da nk tulis...nnt smbung part len2 plak dlm kete...ni basic je...at least kalo korg ade kete bace n pahamkn la...:)
chalosss~~
