HIGH-LOW SPEED RANGE SWITCHING TYPE VALVE MECHANISM FOR INTERNAL COMBUSTION ENGINE |
摘要 |
Several embodiments of variable valve lift mechanisms employing rocker arms that cooperate with high and low speed cam lobes and which are selectively coupled or uncoupled so as to operate the valve dependent upon either the low speed cam lobe configuration or the high speed cam lobe configuration. The construction is such that there are no bending loads placed on the valve stems and the actuating mechanism is relatively light and can be carried at least in part independently of the rocker arms so as to reduce the reciprocating masses and improve engine performance.
