sorry suma....

sorry suma sbb aku tak dapat nak luangkan masa "update" blog nh....

aku bkn x mo "update" tak da time...

arini pn aku dpt update sbb aku dah masuk UNIMAP continue aku nya study in Degree of Product Design..... for the first time aku pn no idea nape diorang bg benda yg aku x mintak actually aku x mnta pn degree nh.... for the first time aku anta borang UPU aku minta Mechatronic n mechanical.... time rayuan pn mcm tu aku mintak mechatronic and mechanical last2 bg aku product design smpai skrng aku x phm.... dri pe yg aku dgr mechatronic full tp time rayuan tu stilll amik student gak for 2nd intake urm,,, actually aku regret gak..... urm nak wat mcm na aku bkn ada cable a.k.a org yg aku knal ...... ntah lah nape dunia skrng nh aku pun x phm.... tp syukur dapat gak masuk U wat degree wlaupn bidang yg aku x minta...bg aku aku x ska minta2..... urm nth lah.... 

VTEC SYSTEM

VTEC (Variable Valve Timing and Lift Electronic Control) is a valvetrain system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine. This system uses two camshaft profiles and electronically selects between the profiles. It was invented by Honda R&D engineer Ikuo Kajitani.[1] It can be said that VTEC, the original Honda variable valve control system, originated from REV (Revolution-modulated valve control) introduced on the CBR400 in 1983 known as HYPER VTEC.[2] VTEC was the first system of its kind, though other variable valve timing and lift control systems have been produced by other manufacturers (MIVEC from Mitsubishi, VVTL-i from Toyota, VarioCam Plus from Porsche, VANOS from BMW, VVL from Nissan, etc).

In the regular four-stroke automobile engine, the intake and exhaust valves are actuated by lobes on a camshaft. The shape of the lobes determines the timing, lift and duration of each valve. Timing refers to an angle measurement of when a valve is opened or closed with respect to the piston position (TDC or BDC). Lift refers to the distance the valve lifts off the valve seat. Duration refers to how many degrees of crankshaft revolution the valve is kept open. Due to the behavior of the working fluid (air and fuel mixture) before and after combustion, which have physical limitations on their flow, as well as their interaction with the ignition spark, the optimal valve timing, lift and duration settings under low RPM engine operations are very different from those under high RPM. Optimal low RPM valve timing, lift and duration settings would result in insufficient filling of the cylinder with fuel and air at high RPM, thus greatly limiting engine power output. Conversely, optimal high RPM valve timing, lift and duration settings would result in very rough low RPM operation and difficult idling. The ideal engine would have fully variable valve timing, lift and duration, in which the valves would always open at exactly the right point, lift high enough and stay open just the right amount of time for the engine speed in use.
VTEC was initially designed to increase the power output of an engine to 100 ps/liter or more while maintaining practicality for use in mass production vehicles. Some later variations of the system were designed solely to provide improvements in fuel efficiency, or increased power output as well as improved fuel efficiency.
In practice, a fully variable valve timing engine is difficult to design and implement. The opposite approach to variable timing is to produce a camshaft which is better suited to high RPM operation. This approach means that the vehicle will run very poorly at low RPM (where most automobiles spend much of their time) and much better at high RPM. VTEC is the result of an effort to marry high RPM performance with low RPM stability

arini

aku ada presentation arini nih aku dah stanby slide tu

dah dkat sebulan last2 hg pa nak tau........

present tak sampai 10 minit hish.........

geram gak aku stanby slide dkt 30 slide last2 time present depan

manager aku sruh skip2 tension sial.....

tp takpa ar "bala" aku dah setel tak pyh nak pening pikir lg......

20 aribulan nih maka tamat lah praktikal aku kat SILTERRA so aku hope apa yang aku dapat

cini bleh jadi pengajaran n pengalaman yg berguna

so tgk ar kira sendiri ar brapa slide aku hehehehe

sudah tiba masa

akhirnya... aku ada time nak update blog yg usang nih,

yes minggu nih, minggu akhir aku kat Silterra suma mmber aku dzar,alip,nizam,chai,wani,eila and our enemy lynn the awek ganazz tak sbar nak abis kan mggu nih.

berakhir mggu nih maka abis lah praktikal kami, maka abis lah sem akhir kami and tggu nak jmpa mmber kat UNIMAP and abis kan presentation dpan pensyarah... Perlis tggu aku hahahah

mggu lpas PLV dah mai wat lawatan gnti pensyarah aku, aku ingat nak mai lawat FAB ke tgk aku wat keja tapi mai check aku nya log book and dia cakap ok lah tu ada bnda nak tulis. aku pon lega lah pastu wat presentation ckit tunjuk aku nya project kat cni.

so minggu nih aku malas nak wat apa nak tggu ari jumaat tggu pkul 5 and kuar dari Silterra dgn
kegembiraan hahahaha.

hari ini

hurm.... hari2 masuk meeting bosan gak, tp kadang aku bleh pelajari apa itu pekerjaan sbnr nya.
dlm dunia pekerjaan ada mcm2 jenis orang ada yg bekerja just nak mkn gaji, ada yang sbb minat, ada yg sbb terpaksa.... hurm mcm2. Tp arini dlm meeting tetiba lpas manager aku mrh2 staf dia bleh plak pas dia blah mcm tu ja..... aku rs dia dh ilang sbr kot sbb kdg2 aku tgk staf kat ctu mcm wat keja pasai trpaksa ja...... cukup bulan mkn gaji apa nak jd jdlh, jnji aku abis keja... aku rs mcm tu lah yg depa pikir kot sbb tu ari2 ada problem.. hurm abis mcm na aku nak minat keja kat ctu. Problem ja mmnjang... hurm yg manager tu bgang sbb mesin br lpas wat maintanance pun kuar alarm lg tu yang dia bgang aku rs..... sbb industri nh masa dn wang tuh pnting tmbh ekonomi mcm nh mn tak dia tak mrh.... board of director meeting mmng dia akan kn soal... hish cuba la ada tggung jwp skit.... arini ada lg engineer kn mrh pasai memndai... kat sini kalau satu wafer rosk nilai adlah RM1000 tp klu satu lot ada 25 keping brapa ribu rugi kira la sndiri, klu satu batch rosak satu batch ada 175 wafer mcm na.. hish byk tu cukup bli civic typeR baru..... huish bg duit tu kat aku pn bgus tmbh time2 aku melest nh..... apa2 pn tggl 1 bulan lbih ja lg pastu relax.....o lh aku pn mls dah nk karang kay pa2 pun good luck suma

adussss.... bosan nya

hish napa la bosan sgt..... skrang ni tggl lg sbulan ja, cpatnya masa brlalu. Tp aku rs tak bleh nak "suit" ar kat tmpat praktikal nh. Sbb mcm aku bg tau ari2 kat article lm aku aku tak sesuai ngn industri nh.... bosan giler. asyik mai keja pagi mesyuarat pas tak da org bg keja lepak dpan PC smbil msj, pkul 12 lunch ,tggu keja lagi tak da dok lpak lg ,smpai pukul 5 blik.... ari2 mcm tuh bosan giler bek aku wat praktikal kat bengkel ada gak keja x la ari2 bosan mcm nh..... hurm. sbnrnya aku rs diorang tllu cbuk kot, smpai jrg amik tau. lg pon production slow giler, dr apa yg aku tgk ar.... tak tau btul ke tak..... hurm tp syukur gak ar dpt praktikal. urm mcm2 bnda aku cuba wat nk ilang bosan. hish tak pa sbar je lah sebulan lbih ja lg x lm...... pastu aku nak rilek tng fikiran.....

sebulan lbih lagi..............woi

tak sbr lah aku nak abis praktikal yang mmbosan kan nih kadang2..... dok tak dok pjm2 celek pjm celek sebulan lebih ja lagi..... hope abis cpat lagi best, semakin ari perasaan malas lesu segan campur dgn berat buntut ang suma2 lah berat nak ja abis cpat2..... kadang2 aku hope sgt silterra ih shutdown tak tau napa.... lg pun cni pun cam ada maslh ja cuma depa staf2 kat cni tak mo ckp.... hurm cpat lah abis bosan nyer................
