Venttiilinohjaus
Venttiilinohjaus refers to the mechanical system responsible for controlling the opening and closing of engine valves. This process is crucial for the efficient operation of internal combustion engines, as it dictates when fuel and air enter the combustion chamber and when exhaust gases are expelled. The primary components involved in venttiilinohjaus typically include the camshaft, tappets or lifters, pushrods, rocker arms, and the valves themselves.
The camshaft, driven by the engine's crankshaft, features lobes that are shaped to push on the valve
The forces generated by the camshaft are transmitted through a series of components to operate the valves.
