vezérmtengely
A vezérműtengely, or camshaft, is a crucial component in internal combustion engines. Its primary function is to control the opening and closing of the engine's intake and exhaust valves. The camshaft is typically a rotating shaft with a series of lobes or cams arranged around its circumference. As the camshaft rotates, these lobes push on the valve lifters or rocker arms, which in turn operate the valves. The shape and timing of these lobes are precisely designed to ensure that the valves open and close at the correct moments in the engine's combustion cycle, allowing for the efficient intake of fuel-air mixture and the expulsion of exhaust gases.
The rotation of the camshaft is synchronized with the engine's crankshaft, usually through a timing belt, timing
