Infiniti VC-T made
Infiniti 2.0 liters VC-Turbo gasoline engine is the world’s first the amount of money production variable compression ratio engines.
VC-T technology uses a variable compression ratio advanced multi-link mechanism, the toggle link mechanism on the original, and an additional set of multi-link mechanism and a control shaft. When a change of the compression ratio, harmonic drives to rotate and drive transmission arm, the transmission arm to drive the control shaft is rotated, when the control shaft is rotated, the lower link will lead to a multi-link structure rotates, and swing lever occurs such that the piston height to reach the top dead center along with the change, so that the compression ratio achieved. Supplied from 8: 1 to 14: 1 compression ratio between arbitrary ratio. When the engine load is low, the use of a high compression ratio, fuel economy is focused; using a low compression ratio, to adapt to high supercharging value, bringing the high-output high load. Taking into account the power and fuel economy.
VC-T2.0T variable compression ratio engine in addition to technology, used a dual injection (direct injection manifold injector +) and cyclic bis (Atkinson cycle + Otto cycle) technology. Maximum power of 200kW (272Ps), peak torque of 390Nm. M274 engine fuel consumption compared to the current use declined by about 27 percentage. VC-T2.0T this engine will be mounted on a whole new generation QX50.
