Low-rpmOperation

For good fuel economy andsmooth operation, both valvesfollow the smaller cam lobes,providing passenger-car-typeperformance at low enginerpm (revolutions per minute).

Horsepower rises steadily acrossthe switch-over point to provide asmooth transition between thelow-rpm and high-rpm modes ofengine operation.

High-rpmOperation

For higher engine power output,both valves follow the larger, centercam lobe, providing performance athigh rpm that is similar to a racingcar engine.
