THE WORLD’S FIRST PRODUCTION-READY VARIABLE COMPRESSION RATIO ENGINE
HONG KONG – INFINITI will present VC-Turbo (Variable Compression Turbo), the world’s first production-ready variable compression ratio engine and one of the most advanced internal combustion engines ever created, on September 29 at the 2016 Paris Motor Show (Mondial de l’Automobile).
More than 20 years in development, INFINITI’s new four-cylinder turbocharged gasoline VC-Turbo engine represents a major breakthrough in internal-combustion powertrain technology.
“VC-Turbo 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 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.”

COMPARISON OF VC-TURBO TECHNOLOGY IN HIGH AND LOW COMPRESSION RATIOS
- When a change in compression ratio is needed, the Harmonic Drive turns and moves the actuator arm
- The actuator arm rotates the control shaft
- As the control shaft rotates, it acts upon the lower-link, which changes the angle of the multi-link
- The multi-link adjusts the height the piston can reach within the cylinder, this changing the compression ratio.
WORLD’S FIRST TECHNOLOGY
INFINITI VC-TURBO ENGINE
VC-Turbo 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-Turbo 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-Turbo 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.
More information on the world-first VC-Turbo engine will be presented by INFINITI at Mondial de l’Automobile on September 29, with the company’s press conference taking place at 12:30 p.m. local time.
