Infiniti will show a VC-T engine (Variable Compression-Turbocharged), which it claims is the world’s first production-ready one. The advanced internal combustion engine debuts on September 29 at the 2016 Paris Motor Show, aka Mondial de l’Automobile.
“VC-T technology is a step change for Infiniti,” said Roland Krueger, president of Infiniti Motor Company. “It is a revolutionary next-step in optimizing the efficiency of the internal combustion engine. This engine 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 significant because engines are no longer limited by a fixed compression ratio. The VC-T engine technology raises or lowers the height the pistons reach; the stroke. 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 engine control logic automatically applies the optimum ratio, depending on the driving circumstances.
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.
