Internal combustion engine, has switching unit acting through control paths, where number of control paths is smaller than number of value or valve assembly operating with common mode

摘要

The engine has two valves (1) or valve assembly exhibiting an operating mode that is switchable by switching units (4b) which are independent from each other. One of the switching units acts through control paths (5b), where a number of control paths is smaller than a number of the value operating with a common mode. The switching unit attached at a common control path is independently controlled by current or voltage modulation.
