You have to raise "filling efficiency", in order to obtain a high output. Being required of a cam is lengthening time which the valve's is opening. It is necessary to increase the amount of cam lifts in order to lengthen time which the valve is opening. The negative acceleration will become large if the amount of lifts is increased simply. The "jumping phenomenon" in which a valve separates from a cam, and the "bounce phenomenon" which is bounded when a valve contacts a valve sheet ring occur because when negative acceleration becomes large, the acceleration of a valve will exceed the acceleration of a cam. These phenomena not only spoil the performance of engine original but cause breakage of engine. The high camshaft must realize the conflicting element with which "extension of time which is opening the valve", and "reduction of negative acceleration". JUN high camshaft took positive acceleration large , and the action time of negative acceleration is keep a long time by shortening positive action time. By doing so, when a valve moves from opening operation to closing operation, a valve can move as smooth operation and can prevent jumping. Since positive acceleration becomes large at the side of close, the valve just before closing is added the strong brakes by the cam. The bounce phenomenon is prevented. The time near the maximum lift can be kept for a long time by opening a valve in a short time. Therefore, the good valve motion of efficiency is possible. The simulation and an experiment of the valve motion system are conducted based on such design theories, and a profile is determined. Here is the true performance for which a high lift camshaft is asked.
Note: Special valve springs required.
