Introduction

CAMS
Control the breathing channels (valves) of an IC engine
Connected to camshaft which is operated by crankshaft
Cams push open valves at proper time & guide their closure
But they are inflexible except VTEC & VVT-I
Engineers could not vary timing, lift & duration of valve opening infinitely.

Working of conventional engines

The crankshaft turns camshaft which operates valves by mechanism as in figure
Spring brings back valve to initial position
Timing of engine valves depends on shape of cams.

Conclusion

Even though some disadvantages are present, we can expect electrohydraulic & electromechanical valves to replace the conventional camshaft technology.
