Nissan’s Two-Pronged Attack On Obsolete Diesel

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. 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.

EU carmakers race to replace discredited diesel engines with something more palatable, and today’s flurry of electric car announcements at the Paris auto show are testament. Japan’s Nissan embarks on a pincer attack against diesel. Nissan leads world markets with its all-electric LEAF. Today however, the company showed something more conventional, and yet revolutionary, that might hasten diesel’s demise: An engine with all the power, but none of the NOx.
