Many automakers are investing heavily in small displacement turbocharged petrol engines naming Mercedes-Benz, Volvo and Honda as but a few. In an effort to take things a step further Nissan is developing variable compression technology (VC-T) through its luxury Infiniti line to maximise performance from the turbo.

The world’s first engine of this kind that is production-ready will be presented at the Paris Motor Show on the 29th September and is the culmination of 20 years’ worth of development by the Japanese manufacturer.

Nissan has found a way to counteract the limitations of fixed compression ratio found in internal combustion engines by developing an engine that is able to vary its compression ratio.
This magic is performed by raising or lowering the height that the pistons reach within the cylinder enabling it to change engine displacement when required. Nissan’s press release describes how this works:

“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.”

Nissan’s latest development will reduce engine noise and vibration, return better mileage and reduce emissions. In addition, VC-T engines are also reported to be tidier and weigh less vs small displacement turbo engine options.
