Toyota has something new up its sleeves - Valvematic, an evolution
of the VVT-i mechanism which now incorporates continuous valve lift
control together with VVT-is existing valve timing control.
Valvematic also eliminates the need for a throttle valve, instead
controlling the volume of intake air using valve lift
instead.
According to Toyota, an improvement of 5% to 10% can be seen with
fuel efficiency, as well as an improvement of 10% with the power
output on a similiar engine displacement comparison. Toyota also
mentions reduced CO2 emission as well as improved acceleration
responsiveness.
The first Valvematic-equipped engine will be a 2.0 liter model,
most likely a replacement for the 145 horsepower 1AZ-FE engine
which has been pretty much slotted with different tune levels into
all Toyota cars in the C-segment and above. The trademark
Valvematic was registered by Toyota a few months ago, so alot of
people have been expecting this. One of the first few cars to get
the new Valvematic 2.0 liter engine are the 2.0 liter versions of
the recently launched twin sedans Toyota Allion and Toyota Premio.
The 2.0 liter variants are set to debut in Winter 2007.
