Valve mechanism of internal combustion engine |
摘要 |
A valve mechanism of an internal combustion engine is of a type which has at least two cams for each intake (or exhaust) valve. One cam is shaped to allow the associated engine to exhibit a marked fuel saving characteristic and the other cam is shaped to also the engine to produce a higher torque at relatively low (or high) engine speed. Upon a cam switching between these cams, at least one of the cams is subjected to a phase change before and/or after the actual cam switching. As a result, the undesired shock at the cam switching is eliminated or at least minimized.
