Beetje oud maar nieuw voor velen;)

To enable the over-expanded cycle (sometimes referred to as Miller cycle, as in Fig. 1) to work properly over different loads, the engine needs Variable Valve Timing (VVT) and Variable Compression Ratio (VCR). VVT is now a common technology used by different manufactures such as BMW (the first with the Valvetronic), Nissan (VVEL) and Toyota (Valvematic). However, VCR is a more complicated technology to be achieved. Saab [2] developed such a system during the last decade of the 20th century, but it never went into production. Also, if we do a find in "Google Patents" there are over 100 patents on that subject, but so far, only one car brand is scheduled to release a commercial VCR engine. It is Nissan’s VC-Turbo engine, which is scheduled to equip the upcoming 2019 Nissan Altima model.
