大家一起来分享我们常常都会看到车后面的字母vvti.vvt..vtec..ivtec mivec..到底它们的功能和运作是这样的，我在网上收集一点资料。如果大家有什么补充的话可以一起来学习。
Toyota
VVT - Variable Valve Timing
VVT-i - Variable Valve Timing-Intelligent
VVTL-i - Variable Valve Timing & Lifting-Intelligent
Valvematic - Valvematic

Honda
VTEC - variable Valve Timing and lift Electronic Control (now honda's name does not really represent it's tech, because for VTEC, there's actually no "timing")
i-VTEC - Intelligent-variable Valve Timing and lift Electronic Control (actually honda lump a lot of things as i-VTEC, because the VTEC name is just too popular)
VTC - Variable Timing Control
A-VTEC - Advanced VTEC

Nissan
CVTC - Continuous variable Valve Timing Control (not to be mistaken with CVT Transmission though)
Neo VVL - Neo Variable Valve Lift
VVEL - Variable Valve Event and Lift

Mitsubishi
MIVEC - Mitsubishi Innovative Valve timing Electronic Control
MIVTLEC - Mitsubishi Innovative Valve timing and Lift Electronic Control (actually there's no MIVTLEC, Mitsubishi used to call its VVL type tech as MIVEC also back in the 90's. Now, it also called its VVT-i type as MIVEC

Mazda
S-VT - Sequential Valve Timing (actually i'm not too sure if this is VVT type or VVT-i type)

Ford
VCT - Variable Cam Timing

Perodua
DVVT - Dynamic Variable Valve Timing

Proton
VVT - Variable Valve Timing (not to be mistaken with IAFM)
CPS - Cam Profile Swtiching

Hyundai
CVVT - Continuous Variable Valve Timing

还是不明白差别，可以直接讲他们之间的mechanism 是怎样吗？
