VTEC Explained...

TVaddict SG

thanks but does anyone has the answer to my question apart from the name difference?

KLZW SG

vti is just a variant of civic.. vvti is corolla's variable valve timing technology.. which acts on the exhaust valves.. closing and opening then at different times at different revs to maximise efficiency..

as for vtec, it modulates both the valves' timing and lift.. in both the exhaust and intake valves.. in honda's normal vtec this is optimised for fuel efficiency and low end torque.. as for sports models its optimise for maximum performance.. while not sacrificing low end torque.. only in the i-vtec engines.. found in accords, odysseys, s2000.. except civics and jazzs and city

Theatre Of Dreams SG

to make it simpler, vti is among the range of civics available. exi, vti, vti-s, in ascending price order...

vvt-i & vtec are the technological branding of the toyota & honda engines respectively. from the above postings u should know what they stand for already...

You had me laughing there, GTI= Got Turbo Inside??!!

No lah, it should be Grand Tourismo injection...GTi

TVaddict SG

so am i right to say that only honda uses vtec and only toyota uses vvti?

mushigen SG

Nissan = CVTC.

Other cars also have this variable timing thing, just that they don't call it vvti. maybe patented by Toyota lor.

VTi is a model of the civic.

VVTi is a kind of technology used by toyota in their engines.

Vtec is a kind of technology used by honda in their engines.

Theatre Of Dreams SG

valves control the one way entry of air-fuel mixture into the cylinder and one-way exit of the exhaust gases...

U-shape? what do ya mean?
