What does variable cylinder technology mean?

Variable cylinder technology, called variable cylinder management, is a variable cylinder management technology. By closing the single cylinder, the 3.5LV6 engine can be switched between three cylinders, four cylinders and six cylinders, and the engine displacement can be changed between 1.75 and 3.5L, which greatly saves fuel.

Variable cylinder technology is usually used in multi-cylinder large displacement engines, such as V6, V8, V 12, etc. Because these vehicles don't need high power output in daily driving, especially in increasingly congested cities, the combination of large displacement and multiple cylinders is a bit wasteful, and small displacement can't meet people's demand for driving pleasure, so in order to solve this contradiction, cylinder replacement technology came into being.

Variable cylinders can control the closing of some cylinders when high power output is not needed, thus reducing fuel consumption. Of course, today's small displacement engine field has also begun to apply variable cylinder technology. At present, the representative variable cylinder technologies are VCM, MDS, DOD and ACT.

Cylinder switching: When the vehicle starts, accelerates or climbs a hill, the engine will put all six cylinders into operation. In the case of medium-speed cruise and low engine load, the system only runs one cylinder bank, that is, three cylinders. During moderate acceleration, high-speed cruise and gentle slope driving, the engine will run with four cylinders. Million car purchase subsidy
