INFINITI will present VC-T(Variable Compression-Turbocharged), the world’s first production-ready variable compression ratio engine and one of the most advanced internal combustion engines ever created, on 29 September at the 2016 Paris Motor Show (Mondial de l’Automobile).
More than 20 years in development, INFINITI’s new four-cylinder turbocharged gasoline VC-T engine represents a major breakthrough in internal-combustion powertrain technology.
Roland Krueger, president of Infiniti Motor Company said, “VC-T technology is a step change for INFINITI. It is a revolutionary next-step in optimizing the efficiency of the internal combustion engine. This technological breakthrough delivers the power of a high-performance 2.0-liter turbo gasoline engine with a high level of efficiency at the same time.”
VC-T technology signifies a new chapter in the story of the internal combustion engine – engines are no longer limited by a fixed compression ratio. The ingenuity of VC-T engine technology lies in its ability to transform itself and seamlessly raise or lower the height the pistons reach. As a consequence, the displacement of the engine changes and the compression ratio can vary anywhere between 8:1 (for high performance) and 14:1 (for high efficiency). The sophisticated engine control logic automatically applies the optimum ratio, depending on what the driving situation demands.
VC-T technology delivers multiple customer benefits including significantly reduced fuel consumption and emissions, greatly reduced noise and vibration levels; it is also lighter and more compact than comparable conventional engines.
