Variable valve actuating apparatus and process for internal combustion engine
摘要:
A variable valve actuating apparatus for an internal combustion engine includes a first valve actuating mechanism to vary a first valve operating condition, and a second valve actuating mechanism to vary a second valve operating condition. A controller controls the first valve actuating mechanism to satisfy a predetermined engine starting condition before a start of a cranking operation or during the cranking operation, with respect to an engine operating condition including the second valve operating condition controlled by the second valve actuating mechanism.
