Feature:
Multi-displacement Svstem (MDS for short) is a unique engine technology; if the engine adopts MDS technology, it can switch the working cylinder of the engine between 8-cylinder and 4-cylinder.At the same time, the MDS system can run with 4 cylinders or 8 cylinders by judging the engine load and working conditions. The engine closes 4 cylinders symmetrically, and the remaining 4 cylinders form a V4 engine, so that the engine can still maintain Better ride comfort; in addition, the data given by engine manufacturers equipped with the MDS system is a 20% increase in fuel economy.

This technology is most suitable for multi-cylinder engines, and effectively reduces fuel consumption during traffic jams without affecting the driver’s pursuit of the acceleration stimulation of large-displacement models. For example, after a conventional 8-cylinder engine adopts this technology, it is equivalent to installing two independent 4-cylinder engines, which can run one engine and let the other rest according to the needs of driving.
