At the just-launched Paris Motor Show, Infiniti announced the world's first mass-produced variable compression ratio engine, the VC-Turbo. According to Infiniti official announcement, this engine can adjust the compression ratio of the engine according to the driving state of the vehicle, adjust the compression ratio that is most suitable for the current working conditions, and realize the adjustment from 8:1 to 14:1.
The reason why VC-Turbo can achieve a variable compression ratio is because the crankshaft and the piston in this engine are connected not only to a single connecting rod, but also to multiple connecting rods. Under different driving conditions, the vehicle controls this part of the multi-link by the computer, controls and changes the compression stroke of the piston, so as to achieve the purpose of changing the compression ratio, so that the engine is kept in an optimum compression ratio. under.
VC-Turbo's compression ratio allows stepless adjustment from 8:1 to 14:1.
For the power level of this four-cylinder engine, Infiniti did not give specific parameters. According to official reports, the engine's power tuning goal is to achieve a power of 200 kW (approximately 268 hp) and a torque of 390 Nm. If such a power level can be achieved, this four-cylinder engine will have the same level of power as the current six-cylinder engine, and will be optimized to have better fuel efficiency performance, and there will be more obvious engine noise and vibration. Promote.
It is said that this engine will be used in mass production models in 2018.
Infiniti officially believes that this time achieving variable compression ratio on a mass-produced engine is another revolutionary upgrade that is comparable to fuel injection, catalytic converters, and turbocharging technology. And set a new benchmark in the future engine power, efficiency, and emissions. The actual performance of this engine in the future, we still need to continue to pay attention to the application of mass production models.
