Question

DentroTest · Accepted Answer

The valve timing system is the set of mechanical elements (camshaft, valves, springs, tappets, etc.) whose primary function is to synchronize and regulate with total precision the opening and closing of the intake and exhaust valves. In this way, it allows clean air or fresh mixture to enter the cylinder during the intake phase and the burned gases to be expelled to the exhaust manifold after combustion. By contrast, the fuel supply system deals exclusively with storing, filtering and delivering fuel from the tank to the cylinders or injectors, while the transmission system is responsible for transferring the rotation and mechanical power from the crankshaft to the driving wheels.
