Don't say 'fake' la.. use 'virtual' instead.

Can. Give your horse a dose of steroids (NOS). But beware that your horse may died of heart attack (blown engine).

people can terasa wei

Maybe the 'gay' he meant is the happy/merry type, not the homo type.

Vtec

Vtec have the same idea with DVVT and VVT-i. It acts like a normal fossil combustion engine in low RPM, however when the user revs until certain limit (usuall 5000rpm). The valve timer would activate (this is what people usually calls Vtec change) and produce a noisy sound.

It sounds a little bit like a 2-stroke motorcycle engine revs high. You feel like the torque suddenly increases and you have more power to accelerate.

What actually happens is that the valve intake open longer than normal. Allowing more air to come into the combustion chamber. The more air in the chamber, the more efficient the fuel burns.



I LOLed.....

hello
where can I get more information about dvvt and vvt?
i tried google everything about these title, especially dvvt but found little information.
thanks

dvvt and vvt is the same..

When talking about these abbrevation, you have to make sure you are taking "marketing keyword" vs "marketing keyword" instead of "marketing keyword" vs "general term".

VVT, variable valve timing as general term, can be said to mean "the engine have this variable valve technology", but not specific technology from specific company. And as a general term, it basically encapsulate all the valve technology you know out there.

VVT, as marketing term, can also means the technology used in the 15+yrs old engine 20valve 4AGE - which is vastly different from VVT-i (another marketing term) from Toyota of current cars.


AFAIK, DVVT is the marketing term for Perodua VVT technology. However, I'm not sure which VVT you compare to - the 15yrs old one or the general term. If you mean the 15yr old one, it is definitely not the same.

VVL neo should be in list... one of most powerfull engine by Nissan... design to beat vtec,,,

Already mentioned few pages back.

p/s: Of course it will beat VTEC, because it is more advance (refer to the link above).

im comparing to vvti..

thanks
but seems to be hard to find information for both technology
searching on journals also not give better result

Just dyno my car...

while japs are still into valve tech... vw already got http://en.wikipedia.org/wiki/Fuel_Stratified_Injection

is it better than all these funny valve thingie?

Huh? The wiki point to the technology that the japs already have in the 90s. While VW started in early 2000.
