Camshaft and valves
WebIntroduction. For an internal combustion (IC) engine to operate, all of its components must perform their functions at very precise intervals in relation to the motion of the piston. To … WebJul 21, 2024 · The shafts must be kept in sync so that the valves open and close at the correct point in the piston’s travel. How Variable Valve Timing Works . In a traditional engine, valve timing (when the valves open and close) is fixed. But with a modern, VVT system, the position of the camshaft(s) can be adjusted, thereby altering valve timing.
