What is Toyota Valvematic?

Dubbed Valvematic,;it combines the automaker’s existing VVT-i variable valve timing setup;with a mechanism that constantly controls the intake valve lift volume. Valvematic helps optimize performance and fuel efficiency by adjusting airflow volume based on the engine’s operating conditions.

What is Valvematic?

Tokyo ― TOYOTA MOTOR CORPORATION (TMC) announced today that it has developed Valvematic*, a variable valve lift mechanism created through combining VVT-i (Variable Valve Timing-intelligent), which continuously controls intake valve opening/closing timing, with a new mechanism that continuously controls the intake valve …

What is VVTi in Toyota car?

VVT-i stands for Variable Valve Timing-Intelligence, which is Toyota’s name for the variable valve technology it uses in most of its vehicles. Some variable valve systems also work on the exhaust valves, which open to let the air-fuel mixture out of the engine.

Which is better VVTi or valvematic?

VVTi does it by changing valve duration, Valvematic adds valve lift and fuel control. I expect Valvematic feels a little stronger at lower revs, which probably matters for drivers of automatic cars.

Is VVTi like VTEC?

i-VTEC uses not only timing but also the lift aspect of the valves, while VVTi uses only the timing aspect. The technology that uses timing and lift aspect developed by Toyota is called VVTL-i and can be equated with that of i-VTEC of Honda.

Is VVTI better than VTEC?

VTEC (Variable Valve Timing and Lift Electronic Control) is a valvetrain system developed by Honda that allows engines to achieve turbo level specific output without the bad fuel efficiency that turbocharging normally introduces….Comparison chart.
