VVT-i
VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 5-valve per cylinder 4A-GE engine. The VVT system is a 2-stage hydraulically controlled cam phasing system.
VVT-i, introduced in 1996, varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt, scissor-gear or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust valve closing and intake valve opening result in improved engine efficiency. Variants of the system, including VVTL-i, Dual VVT-i, VVT-iE, and Valvematic, have followed.

VVT (gang)
VVT is a Tamil gang in Toronto believed to be named after the Sri Lankan town of Valvettithurai. It was founded in the early 1990s by Tamil immigrants. The VVT had a strong presence in the west end of Toronto (in particular in Etobicoke and certain areas in Old Toronto and East York) and was regarded as being very business savvy and motivated by the profits of crime. The VVT were considered to be highly organized with members ranging in age from their early teenage years to men in their 30s, with members from to 100-500 strong. In the mid to late 90's and early 2000s the VVT had an ongoing war with another powerful Tamil gang called the AK Kannan based out of Scarborough. There was a brief truce in 1998 after community members brokered a peace deal in a Richmond Hill Hindu temple; however, a murder a year later renewed the fighting. VVT is behind many murders in the 90s.
VVT had multiple leaders who represent their respective territories throughout the GTA, Waterloo, Hamilton, Ottawa and Montreal. Even after the deportation of some prominent members, authorities believe this gang is still in operation through its younger generation. Police believe VVT members are heavily involved in drug trafficking, fraud, weapon trafficking, counterfeiting, and extortion. This gang is now considered defunct; however, it is still present through younger generations.
